3.- INSPECTION ON RECEPTION AND STORAGE
3.1 All valves will be examined on reception, to ensure that they have not suffered any damages
during transport, and the supplier will immediately be informed of any damages observed.
3.2 Valves leave the factory in open position as a measure of protection and to ensure that no
foreign body can damage the ball, except fail to close actuated valves (Actuator normally in closed
position).
3.3 WARNING!
Valves will be stored under cover and protected from inclement weather conditions and foreign
bodies.
3.4 Valves will not be unpacked until they are to be definitively installed, except for purposes of
inspection. After inspection they will be packed again
4.- INSTALLATION
4.1 The handling and transporting of the valves must be carried out with extreme precaution and
using the necessary and adequate means on the basis of their size and weight, in this way avoiding any
risks to the persons that handle them.
4.2 WARNING!
Never use the wrench to hold the valve during handling, assembly or transport.
Check the condition of the valve, firstly to detect any possible damages caused during their
transport and/or handling.
Likewise inspect the inside of the valve, as well as the interior of the pipe that connects up to the
valve. It is of utmost importance that there are no foreign bodies that could damage the valve seats,
insofar as these parts are fundamental to the correct operation of the valve.
TRUNNION MOUNTED 3 PIECE BODY VALVES ASSEMBLY & MAINTENANCE PROCEDURES REF. DOC.MMM6000E Rev.4 – January 2017
Page 7 of 39
WARNING!
When it is known or assumed that the valve has to be installed at a collection point for waste,
such as welding slag, rust or scale, protective filters or screens must be placed, temporarily or
definitively (depending on the installation), upstream, before connection with the valve.
The valve must be installed in such a way that it is accessible for the necessary periodic
inspection and maintenance required guaranteeing the performance levels for which it has been
designed.
JC Standard STF & STR Series construction have been designed without fluid direction
preference – “They are Bi-directional”
The valve can be installed with the stem in any position, although it is recommended that the
installation will be done in a vertical position, with the stem upwards.
WARNING!
The valves must not support stress from the piping, the installation must be carried out
ensuring correct alignment and parallelism in order to ensure that it is not subject to any
unexpected stress.
Make sure when installing the valve that the flange seal that connects up to the valve is
correctly fitted, following the seal manufacturer’s instructions, also ensuring that it is compatible with the
circulating fluid.
Install the valve to the line using the correct size and type of coupling flanges and the
appropriate gaskets (for RF) or sealed gaskets (for RTJ). The design of the valve allows the fluid can
come from any direction.
The body of the JC Trunnion mounted 3 piece body valve will be supplied with assembly
drills machined in the cover for the assembly of the actuator. Please contact us for the location and
dimensions of these drills.
IMPORTANT!
After installation run a final check on the valve, opening and closing it to make sure that it is
working perfectly.
TRUNNION MOUNTED 3 PIECE BODY VALVES ASSEMBLY & MAINTENANCE PROCEDURES REF. DOC.MMM6000E Rev.4 – January 2017
Page 8 of 39
WARNING!
Make sure that the fluid used in cleaning operations and the way in which the cleaning is
done are compatible with the installed valve.
Having finalised the final cleaning operations prior to bringing the valve on-line, if filters have
been installed they can be removed or, on the other hand if the user considers that rust or scale
formations may be encountered, they must be left permanently in place.
¡IMPORTANT!
When ball valves are destined to end line, you should reduce the hydrostatic proof pressure of
the line to 1.1 Rating pressure.
¡IMPORTANT!
After fixing the valve, travel stops “OPEN” & “CLOSED” have to be adjusted to the actuator
taking into account the bore of the ball and the position of the key of the stem.
5.- ON-OFF SERVICE
JC Trunnion Mounted 3 piece body valves are only recommended for ON-OFF service.
They close by rotating the stem or the handwheel of the gear-box clockwise. The open and closed
exact position is determined by the radial location of the stem key with respect to the fluid passage.
Body central line. When the key slot is perpendicular to the fluid passage, the valve is closed.
Gear-boxes are marked with indication arrows.
6.- DOUBLE BLOCK & BLEED
JC Trunnion mounted 3 piece body valves are appropriate for sealing different fluids in both
ends.
The installation of a vent valve provides a safe and convenient method to check the efficiency of
the tightness of the seats of the valve, as required by the double block and bleed function.
TRUNNION MOUNTED 3 PIECE BODY VALVES ASSEMBLY & MAINTENANCE PROCEDURES REF. DOC.MMM6000E Rev.4 – January 2017
Page 9 of 39
7.- PREVENTIVE MAINTENANCE
7.1 Preventive maintenance operations essentially consist of periodic inspections to ensure that the
valve is working correctly.
7.2 Valves must be opened and closed at least once every 6 months and, should such be required
on the basis of the fluid or the application of the valve and its importance, opening and closing check
plans will have to be established for shorter periods.
7.3 The user will be responsible for establishing opening and closing plans that are adequate for the
work conditions and the fluids used!
7.4 WARNING!
Never leave the valves open or closed for a long period of time.
7.5 A very high torque increase could be due to the inclusion of foreign bodies in the seats. It is
important not to force the valve! Proceed with an inspection of the seats in order to avoid damaging the
ball.
8.- MAINTENANCE OPERATIONS
PRECAUTIONS BEFORE DISASSEMBLY!!
Make sure that the line has been closed and depressurised.
Open and close the valve several times in order to release the pressure and drain the valve
cavity.
WARNING !!
Wear protective clothing adequate for the circulating fluid. (Comply with the safety
guidelines laid down by the Company!)
The replacement of parts must be done using original JC spare parts!
TRUNNION MOUNTED 3 PIECE BODY VALVES ASSEMBLY & MAINTENANCE PROCEDURES REF. DOC.MMM6000E Rev.4 – January 2017
Page 10 of 39
The manufacturer will not be responsible for the malfunctioning of the valve if original JC
parts are not used!
Once the pressure is relieved, the valve in half-open position has to be drained at 0 psig through
the drain plug (50).
It is recommended that when it is necessary to replace the gaskets and packing, body
connector gaskets and graphite gaskets of the rest of the valve should also be replaced.

1.3 Reference Documents
- JC Valves Product Data Sheet - Notify body report and Certificate - JC Valves Maintenance and installation instructions (This document). - Special operating Instructions :
Valves manufactured by JC Valves can be equipped with a variety of: Operating mechanisms, such as handwheel, gear, electric actuator, hydraulic actuator or pneumatic actuator. Motorized valves are supplied with the actuators installed and torque and position limits correctly adjusted. For opening the valve, handwheel must be rotated counter-clockwise. Open and close position will be done by the stop regulation devices.
TRUNNION MOUNTED 3 PIECE BODY VALVES ASSEMBLY & MAINTENANCE PROCEDURES REF. DOC.MMM6000E Rev.4 – January 2017
Page 32 of 39
Unless otherwise specified, gearing in most cases is sized to close with a maximum 35Kg rim pull on the gearing handwheel at a differential shut-off pressure equal to the class of the valve. If the actual differential pressure is known, or a different rim pull is required, this information should be specified as the gearing size may change. The information required to custom size gearing is as follows: a) Operating conditions b) Differential shut-off pressure c) Maximum allowable hand wheel rim pull d) Desired hand wheel orientation. The high speed of operations in modern industry and the necessity of making process plant operations automatic have increased the need for motor operated valves. Such applications include those where the valve: 1. Is too large or has too high a differential shut-off pressure for manual operation. 2. Is not accessible for manual operation, 3. Is part of a system requiring simultaneous operation of many valves, 4. Must be triggered form a remote location, as is often essential for emergency shut-off in hazardous areas. Actuator manufacturer’s instructions must be followed in case the valve is equipped with an actuator (electric, pneumatic or hydraulic). Torque, limit switches and additional parameters are adjusted in factory before shipment. Contact JC Valves before changing any parameters. Any actuator mounted on a JC Valve has a position indicator for indicating if the valve is open or closed. This position indicator depends on the actuator type; it can be a digital or a mechanical indicator. Generally motor operating units, as illustrated are top-mounted. Side mounted units can be supplied where deemed necessary by valves manufacturer and actuators supplier. All valves are furnished with special purpose yokes designed for the motor operating unit to be used, following ISO 5211. Electric driven motor actuators consist of a special motor, a reduction gear, and necessary control components, all contained in a weather resisting enclosure, suitable for outdoor installation. Moreover units can be supplied with all necessary contacts for local or remote indication. For hazardous locations, electric control units can also be furnished, on request, with flameproof or explosion proof enclosures, depending on specifications followed by the customer.

Tandem gate valves for Hydrogen service. Metal seated HIPPS ball valves. Double metal seated ball valves. From cryogenic temperature to high temperature range Ball valves. Flow regulation Globe manual valves. Special dimension valves. Customized %’s of material content out of standards. Etc.
JC Valves is the most reliable supplier for the most severe requirements and conditions.
The material of constructions of a JC Valves are specified in the JC Valves Datasheets and in the main literature. It is especially important that the designer of the SIF checks for the material compatibility considering on-site chemical contaminants and fluid conditions. If the JC Valves are used outside the application limits or with incompatible materials or environment, the reliability data and predicted SIL capability becomes invalid.
3.4 Design Verification
A detailed Failure Modes, Effects and Diagnostics Analysis (FMEDA) report is available from JC Valves for this product. This report details all failure rates and failure modes as well as expected lifetime of the product. The achieved Safety Integrity Level (SIL) of an entire Safety Instrumented Function (SIF) design must be verified by the designer via calculation of PFDAVG considering the architecture, proof test interval, proof test effectiveness, any automatic diagnostics, average repair time and the specific failures rates of all equipment included in the SIF. Each subsystem must be checked to assure compliance with minimum Hardware Fault Tolerance (HFT) requirements. The failure rate data listed in the FMEDA report is only valid for the useful lifetime of the JC Valve. The failure rates will increase after this useful lifetime period has expired.
3.5 SIL Capability
JC Valves are suitable for use in a safety instrumented system up to SIL 3 A proof test has to be performed once a year in order to accomplish with the safety requirements.
3.6 General Requirements
The JC Valve will be moved to its defined safe state (closed) in relation to the specific hazard scenario. All SIS components must be operational before process start-up. The User shall verify that the JC Valve is suitable for use in safety applications by confirming the JC Valve nameplate and model number is properly marked. Personnel performing maintenance and testing on the JC Valve shall first be assessed as being competent to do so. Result from periodic proof tests shall be recorded and periodically reviewed. The JC Valve shall not be operated beyond the useful lifetime.

4.0 Installation and commissioning
4.1.- SAFETY INSTALLATION AND STORAGE - The handling of valves, both whilst they are still inside the packaging and when they have been removed from it, is to be undertaken in accordance with the Assembly & Maintenance Manual. - Check the packaging is fully secure in the event that it is to be moved. - Always use endorsed chains and mooring straps of sufficient strength for moving the valve or the crates. Make sure they are in good condition. The weight of the crates is specified on them, and the weight of the valves is indicated on the corresponding drawings. - Hold the boxes by the marked mooring points. - Never pass a valve or a crate through the air over a person. - Storing valves must be carried out according the Assembly & Maintenance Manual. - When opening the crates, be careful with packing nails. Never leave the point of a nail sticking out, remove the nail completely from the crate if necessary. Do not handle crates with bare hands are there could be splinters. - When the valve is installed at a height above the ground, follow local safety regulations on working at heights. - When the valve is welded on to the line, use suitable protection and safety equipment.
