1BALL VALVES

BALL VALVES - INTRODUCTION

2

The ball valve is basically a ported sphere in a housing.

Rotation of the sphere by 90 changes the position from open to closed, and from closed to open.

Characteristics:

Smooth operation Low pressure loss High Cv Compact design Fire safe

Ball is guided by stem on the top and trunnion on the bottom:

Seat is made upstream / down stream Lower torque Higher cost

TRUNNION MOUNTED BALL VALVES

They are also used for smaller sizes than those indicated above, with benefit of lower torque and higher reliability, but at a greater cost

BALL VALVES - CLASSIFICATION ASSEMBLY TYPE

5

SIDE ENTRY BALL VALVES

Most common type of ball valves

Normally forged

Ball is introduced through a side of body during assembly

Fully maintenance can be done only when valve is disassembled from the pipeline

BALL VALVES - CLASSIFICATION ASSEMBLY TYPE

6

The Top-entry valve types have a major application when a frequent maintenance must be carried out and the valve cannot be easily removed from the pipe.

In this valve model, all the internals can be easily dismounted by loosening the bonnet of the valve and removing the ball, the seat-holders and the shaft.

When mounting the valve again, the seat-holders have a system to regulate the compression of these to the ball.

TOP ENTRY BALL VALVES

BALL VALVES - CLASSIFICATION CONSTRUCTION

7

SIDE ENTRY BALL VALVES SPLIT BODY

Bolted type

Two or three pieces

Possibility of full maintenance by disassembling the valve


8

SIDE ENTRY BALL VALVES FULLY WELDED

Fully Welded ball valves are available for those cases when leakage throughout atmosphere must be absolutely avoided such as in gas transmission pipelines.

Valve is built in three pieces fully welded constructions.


9

SIDE ENTRY BALL VALVES SCREWDED AND WELDED

Monoblock type

Only for small sizes (up to 2)


10

SIDE ENTRY BALL VALVES IN LINE

For sizes up to 6, this type of valve can be used giving the same possibility of maintenance as top entry ball valve but being a construction much more economical.

BALL VALVES - CLASSIFICATION BORE

11

FULL BORE

Ball valves are generally designed so that internal flow passage is large enough to pass flow without a significant restriction. The ID of the bore is the same as the ID of the pipe to which it connects.

Full bore (sometimes called full port) valves also allow for the use of a pig in the pipeline. The pig is a self driven mechanism designed to scour the inside of the pipeline and to remove any process build-up or scale.

BALL VALVES - CLASSIFICATION BORE

12

REDUCED BORE

Often, a system does not require a full bore to accommodate a pig and is not expected to operate at the full capacity of the pipe. This offers an opportunity for reducing equipment costs.

A reduced bore ball valve uses a ball/seat combination which has a smaller ID than the pipe. The nominal valve size is referred to by the outlet size x the ball ID for example 3 x 2.

Reduction is usually limited to one nominal size, but may be increased to two for 16 and larger outlets.

BALL VALVES - CLASSIFICATION SEAT TYPE

13

SOFT SEATED BALL VALVES

The seat design features a deep pocket with a protective lip which makes the design a long lasting design. The seat assembly consists in an outer metallic seat carrier with a soft seat insert. The soft insert is located into a groove in the metallic seat carrier.

The complete seat assembly is floating inside valve body and it is energized by a set of springs which load the seat assembly against the ball preventing leakage from behind the seat.Seat assembly is provided with outer o-ring to avoid leakage through the seat carrier and a graphite back up ring which ensure the tightness in case the o-ring is damaged.

BALL VALVES - CLASSIFICATION SEAT TYPE

14

METAL SEATED BALL VALVES

Similar seat construction is done in case of metal seated valve. However the seat in this case consists only in a metallic seat ring (without any insert).

The surface in contact with the ball is hardfaced with Tungsten Carbide, stellite etc., achieving a minimum hardness of 42 HRC to stellite or convectional hardfaced and 78 HRC to Tungsten Carbide or special hardfaced.

This makes the design long durable and reliable and able to achieve classes V & VI leakage class metal seated

BALL VALVES - CLASSIFICATION TECHNICAL FEATURES

15

Floating Seats The seat assembly, either soft seat or metal seat, which seals against the ball is provided with coil springs on its back side. The coil springs press the seat assembly against the ball making sure the contact between the seat area and the ball even in absence of line pressure. When line pressure increases, the seat differential area (C=A-B) creates a piston effect forcing the seat against the ball. This additional load increases the effectiveness of the seat/ball interface. The higher the line pressure is the greater the piston effect.

Automatic Cavity Pressure ReliefThe pressure-actuated seat construction, used in trunnion ball valves ensures positive relief of excess of valve central cavity pressure. If valve central cavity pressure exceeds a pre-set pressure in the seat, the seat assembly will automatically back-off to relieve the excess of pressure.

BALL VALVES - TECHNICAL FEATURES

16

Double Piston Effect (optional)

With normal floating seats a ball valve is-bi directional, creating a single seal on the seat exposed to line pressure. The opposing seat vents pressure downstream. If the upstream seat fails, it may be appropriate to use the downstream seat as a back up seal to the primary seat. Modified seats can offer this feature. The outer diameter of the seat is designed with a double piston profile, exposing more surface area to cavity pressure that a normal floating seat. In the case of an upstream leak, this enhances the contact pressure between downstream seat and ball. The differential area A= B-C creates a piston effect forcing the seat against the ball.

In such cases, it is recommended that an automatic pressure relief valve be installed to protect the body cavity from excesspressure.

As an option, it is possible to adopt the double piston effect on one side only. Although this eliminates the need for a pressure relief valve, it does make the valve uni-directional.


17

Trunnion Design for Low Torque OperationThe large diameter trunnions provide smooth, easy operation and extended bearing life. The trunnion bearings are stainless steel with heavy-duty PTFE coated.

Double Block-Bleed (optional)Because the floating seats seal, both upstream and downstream, simultaneously, double block and bleed procedures can be performed. With the valve under pressure, the body cavity may be vented or drained to the atmosphere through the bleed valve.

Antistatic Device Internal parts that are insulated from the

body may build up a static electric charge.

When service conditions require electrical continuity to prevent static discharge, this is ensured by the adoption of coil springs to ensure electrical continuity between body, ball and stem

18

Grease Fittings / Flushing injection Three grease fittings are supplied, providing

the ability to inject lubricant into both seat pockets and stem area.

Flushing to clean sealing area



Stem Extension for Buried Service A stem extension is a need when valves are being

installed in underground pipeline making the valve operator non accesible.

RV valves offer a wide variety of stem extensions for manual operated valves as well as for actuated valves, including gas over oil operated valves.

The stem extension includes the complete system of grease injection, actuator gas supply, etc as a part of it.

Anti blow out stemTo assure safety and integrity

Actuator Mounting ProvisionsActuator mounting brackets, shown below, are available as option for users who prefer to install their own actuators. We recommend that buyers specify factory-installed actuators to assure reliable, long life performance and to gain the benefits of RV single source responsibility, single source warranty policy.

One-Way Operating Lever armOperating wrenches are keyed so they may be installed only in one position in line with the bore of the valve, when the valve is in the open position. They serve as an open closed indicator in addition to the stop plate indicator on the bonnet cap. Wrenches are available as an option on full bore through regular port models. Worm gear actuators are required on all larger sizes for manual operation.

Manual Operated ValvesFor manual valves up to 4, operating lever can be provided. Lever operated valves are also provided with a stop plate valve to avoid travel of more than. The lever together with the stop plate provides valve position indication. For valves larger than 4, worm gear actuator is provided.


21

Fire Safe DesignRV valves are of FIRE SAFE design, which substantiallyprevent the leakage when valve is subject to high temperatures.

In case of fire accident inside the valve, seals, and seatinserts (for soft seated valves) are melted and then a metalto metal seat is made between the metallic seat and the ballensuring a degree internal sealing tightness.

All o-ring are also disappeared and only graphite back-uprings remain in seats and valve stem, making the valve tightfor leakages to the atmosphere.

RV valve designs conform requirements of API 6FA, API607and BS6755.

BALL VALVES - CLASSIFICATION GAS OVER OIL ACTUATED

22

This valve is used in gas pipelines and the actuator is powered directly from the line gas pressure.

Valves actuator may be provided with line break detection system which closes the valve in case that the gradient of pressure drop in the line is greater than a preset value.

BALL VALVES - CLASSIFICATION EMERGENCY ASSISTED

23

This valve is intended for protection of turbine/pump in hydroelectric power stations. Valve is assembled in horizontal position and provided with a hydraulic piston to open the valve.

In case of reverse flow which may damage the turbine/pump, this is detected by a pressure transducer which sends a signal to the valve releasing the pressure in the hydraulic piston and allowing the valve counterweight to close the valve in few seconds avoiding line counterflow to reach the turbine/pump.

BALL VALVES - CLASSIFICATION FULLY WELDED

24

Fully Welded ball valves are available for those cases when leakage throughout atmosphere must be absolutely avoided such as in gas transmission pipelines.

Valve is built in three pieces fully welded constructions.

BALL VALVES - CLASSIFICATION API 6A

25

For upstream applications, three pieces side entry ball valve is used in accordance with the requirements of API 6A. Valve classes from class 2000 to class 20000 In sizes from 2-1/16 to 7-1/16 are available.

Material selection is done in full compliance with API 6A requirements.

Valve designs are available to meet Pressure Product Requirement levels PSL-1, PSL-2, PSL-3 / PSL-3G and PSL-4.

BALL VALVES - CLASSIFICATION INTEGRAL DOUBLE BLOCK & BLEED

26

BLOCK & BLEED VALVES

Manifold that combines one or more isolation valves (normally ball) with one or more bleed/vent valves (normally needle) into one assembly/body.

Valves used for double block & bleed isolation, where space is limited and there is weight restrictions also (By instance Offshore industry)

These valves are used mainly for two purposes: Instrument double block & bleed (2" and

below)- Instrumentation isolating, chemical injection, sampling, vent ad drains

In line double block & bleed (above 2").

Valves mainly used in Offshore

BALL VALVES - MATERIALS

RV valves are manufactured using a wide selection ofmaterials such as:

Carbon steel Killed carbon steel for low temperature applications High resistance alloy steels for API 6A applications Stainless Steel Duplex & Superduplex steel Nickel alloys

Materials also meet the requirements of NACE MR-0175/ISO 15156 when sour gas services are specified.

Our technical staff is ready and available to provide customized material selection for those special customer applications RV always provides the customer with suitable information of material selection which is agreed prior valves are manufactured.

For majority of industry applications the following table gives the main guidelines of material selection.

29


Remarks The above table is orientative and intended only for information. In case of Metal to Metal valves seat and ball are both hardfaced with different materials such as stellite, Tungsten Carbide, Chromium Carbide, etc, being the base materials selected upon the valve application and the design pressure/ temperatures.

30


Sealing Material

Commonly O-rings or Lip Seals as used as sealing element of ball valves. The most commonly used materials are O-RINGS: BUNA-N (Nitrilic rubber) VITON including its alternatives of high temperature VITON (up to 210/C) and VITON for

explosive decompression. Others depending on application.

Lip Seals

Lip seals are used normally for more severe applications such as cryogenic services, high temperature or also in nuclear valve application (when the seal must be radiation resistant).

The lip seal is made of different materials such as PTFE, KEL-F, etc, and it is self energized by an internal spring of stainles or inconel alloy.

Lip seals must be mounted in the positive direction of pressure in such a way that fluid improves the sealing load of spring.
