Why Specify CLA-VAL Automatic Control Valves 25

Valve Fully Open

When pressure in the cover

chamber is relieved to a lower

pressure or to the atmosphere, the

inlet pressure opens the valve.

Valve Closure

When inlet pressure is applied to

the cover chamber, the valve

closes drip-tight.

Valve Closure

A Cla -Val “modulating” pilot

control is fitted to automatically

compensate for line pressure

changes.

Main Function

CLA-VAL Model 100-01

There are three HYTROL types:

The Hytrol Valve is a hydraulically operated, diaphragm actuated, single chambered globe or angle

pattern valve.

It consists of three major components, namely: the body, cover and diaphragm assembly. The diaphragm assembly is the only

moving part, and forms a sealed chamber in the upper portion of the valve, separating operating pressure from line pressure.

The synthetic rubber sealing disc, with rectangular cross section,

is supported on three and a half sides by a disc guide and a disc

retainer, and forms a drip tight seal.

The Model 100-01 is the basic valve used in nearly all

CLA-VAL Automatic Control Valves.

Main Valve TYTAN


7

The TYTAN Valve is a hydraulically operated,

diaphragm actuated, globe pattern valve. It consists of three

major components namely the body, diaphragm assembly and

cover.

The diaphragm assembly is the only moving part, guided top and

bottom by a precision machined stem. The disc retainer and

rubber disc form a drip-tight seal with the renewable seat when

pressure is applied above the diaphragm (cover chamber).

CLA-VAL 40-01/640-01 : Typical Application

The CLA-VAL 40-01/640-01 is typically installed where

water supply to a system (inlet to a reservoir, industrial

users, etc) must be limited to a maximum flow rate.

The Orifice Plate assembly may be fixed directly to the

main valve outlet flange, however better control is

obtained if it is installed in stabilized flow conditions

downstream of the valve. The ideal position would be

between one and five pipe diameters downstream of the

valve.

maintain desired upstream pressure to prevent "robbing"

of pressure in upper zone.

The CLA-VAL 50-01/650-01 (Relief Service) is installed

to protect the system or installations against high pressure

surges, eg. when pumps are suddenly shut down. The

valve is installed near the pump on a line discharging to

atmosphere.

CLA-VAL 60-31/660-31 : Operation

Pump off

Starting sequence

Stopping sequence

When the pump is off a hydraulic check feature keeps the

valve in the closed position.

The pump starts against a closed valve. When the working

pump rate is reached the solenoid control gradually opens

the valve to prevent pump surge. This opening rate shall

be fully adjustable on site. The pump opening will be

limited by the pressure sustaining feature; this feature will

ensure the valve opens under controlled hydraulic

conditions. When the sustaining set point is reached, the

sustaining pilot will open fully, thus allowing the valve to

fully open.

The pump requires a closed valve. The shut-off signal will

de-energize the solenoid control to close the valve slowly.

Meanwhile the pump is still working. When the valve is

fully closed the switch assembly shuts the pump off.

The CLA-VAL 124-01/624-01 is commonly mounted above the

high water level in a tank. The float mechanism (CF1-C1) may

be located remotely from the main valve. A stilling well (200mm

minimum diameter) must be provided around the float, as the

liquid surface is subject to turbulence (not supplied with the

valve)

The Float Valve maintains a relatively constant level in storage tanks and reservoirs by admitting flow

into the tank in direct proportion to the flow out of the tank. As the liquid level changes, the float control proportionally opens or

closes the main valve, keeping the liquid level nearly constant.

Retrofit to standard Hytrol valves

The 100-01KO Hytrol main valve provides optimum internal pressure control through a unique anti-cavitation trim (patent-

pending) design. Constructed of 316 Stainless Steel, the seat and disc guide trim components feature dual interlocked

sleeves containing radial slots that deflect internal flow to impinge upon itself in the center of the flow path, harmlessly

dissipating the potential cavitation damage. This unique design also lessens the possibility of fouling if large particles in the

water are present due to the large flow path of the radial slots.

The 100-01KO Hytrol is the basic valve used in Cla-Val Automatic Control Valves for high differential applications requiring remote

control, pressure regulation, solenoid operation, rate of flow control, or liquid level control. The anti-cavitation trim components

can be retrofitted to existing valves if the application indicates an appropriate need. Please consult factory for details.

CLA-VAL 100-42

700 Series Roll Seal


22

The Roll Seal Valve is a hydraulically operated valve

used to control liquid flow by means of a flexible control element (the liner).

The basic valve consists of only two parts a one piece, investment cast body

and an elastomeric liner. The valve body is constructed with internal ribs and

slots forming a grillwork which surrounds the liner to provide support. A

normally closed type valve is formed by the installed liner which covers the

grillwork and seats against the raised seating surface in the valve body.

Upstream pressure actuates the valve to produce valve opening by rolling the

liner off the seating surface and the slotted grillwork. The valve is actuated by

upstream pressure as the loading pressure (pressure supplied to the control

chamber) is varied by an external pilot control system. A typical pilot control

system used to operate the Model 100-42 valve consists of a restriction and a

suitable pilot connected to the valve.

Cla-Val Model 100-42

Upstream pressure is introduced to the

control chamber (the chamber formed

behind the liner) of the Cla-Val Model 100-

42 Roll Seal valve through the control piping

and restrictor. When the pilot is closed, full

inlet pressure is supplied to the control

chamber, thus balancing the force

developed by inlet pressure acting on the

upstream face on the liner. Under these

conditions, the liner remains in the fully

closed position. Since the operating

pressure in the control chamber is greater

than the outlet pressure, an additional

closing force is developed across the liner,

pressing the liner against the surrounding

slotted grillwork area and seating surface.

As loading pressure is lowered slightly

below inlet pressure, the central portion of

the liner is forced to invert and come to rest

against the tip of the control chamber cavity.

Reducing the loading pressure further (but

still higher than outlet pressure) causes the

liner to drape over the cone shaped portion

of the control chamber cavity. This action

causes the outer section of the liner to roll off

the seating surface and a portion of the

grillwork to partially open the valve.

The valve is fully opened when loading

pressure is sufficiently reduced to allow the

liner to roll back completely and expose the

full slot area. Restoring loading pressure

reverses the liner rolling action to return the

liner to the fully closed position.

INTRODUCTION

THE CLA-VAL DIFFERENCE

Control valves form an essential part of the effective and efficient operation of any pipeline system. Selection of these devices is highly dependant on the personal

experience of the engineer, the detail in manufacturer’s product literature and published imperical data. It is often assumed, due to the lack of published field data that

at least, all control valves are the same in performance. Control valves for this reason, are often specified based on the desired function or, for a perceived advantage

which may in essence have no bearing on the valve’s effectiveness.

As an integral component to any pipeline system, control valves should be selected as with all other pipeline components on the cost of ownership which implies

weighing up the initial cost of the valve against; maintenance, requirements, ease of installation, effectiveness of operation, availability of spares and, technical

support and after sales backup.

Cla-Val, when assessed against these requirements and for the reasons outlined below, is the most obvious choice for all your control valves needs.

Low flow conditions cannot be accommodated for in conventional control valves without the addition of paraphernalia such as Vee Ports and the like that may present

additional operational problems. Alternatively, expensive changes to the pipeline are recommended such as installation of reducing pieces and smaller diameter

valves or, installation of low flow bypasses.

Model 600 Cla-Val Hytrols provide a cost effective and efficient reduced port design to cope with low flow conditions.

High pressure drops or excessive flow conditions will inevitably cause cavitation which result in high noise, excessive vibration and damage to the valve. Designs

utilizing Vee Ports do not prevent but aggravate this destructive phenomenon. The use of multiple orifice plates is often not practical in applications where there is

limited space; in addition, the solution is removed from the valve and can lead to error in application.

The specific design of the model 600 CLa-Val with its enlarged flow area around the seat allows for vapour bubbles to slow down before disposing against the walls of

the valve housing, reducing potential cavitation damage. A ratio of 4 to 1 reductions in pressure can be maintained without damage.

In addition, Cla-Val provides a proven, radial design cartridge that can be fitted to its standard hytrol design for severe applications.

The stem of a control valve is often subjected to high differential pressures. Stems of Wye (Y) Pattern (sometimes called semi-straight) designs are centrally guided.

The inclined operation of the stem in addition to its central guidance often leads to excessive wear of the o-ring seals and bearings and subsequent leaks. Vee Ports,

which may cause a number of operational problems, are often specified to provide more controlled guidance to the stem.

The Cla-Val non-magnetic stem as standard is fully guided through its complete stroke by two replaceable bearings.

Pilot control systems form the heart of any control valve design. Most manufactures provide a limited selection of pilot controls or, make use of three way controls

which result in inaccuracy in control due to the shifting of the control point.

The two-way modulating control systems manufactured by Cla-Val are designed to minimize set point fluctuations. Stem movement of these controls are limited to

one-mm, hence the spring is compressed by one-mm maximum, and the modulus of the spring does not change over this distance of compression, resulting in the

set point remaining constant. Cla-Val in addition provides the widest selection of control systems.

It is prudent, regardless of design, to maintain control valves regularly. Large diameter, Wye (Y) pattern valves are difficult to maintain due to the bonnet installed at an

angle.

Cla-Val utilizes a globe pattern design and has only moving part which makes for ease of maintenance

Cla-Val has been available in South Africa since 1977 and has been locally manufactured, under licence to CLa-Val Co., by Dynamic Fluid Control (Pty) Ltd since

1981.

The Local market, because of this relationship has access to more than sixty five years of global experience in real world and demanding control valve operation in

applications such as waterworks distribution systems, fire protection systems, farm irrigation, navy ship systems, ground fueling and industrial fluid handling

systems. In addition, the market is updated and kept on the edge of technological advancement in electronic and hydraulic control systems through CLa-Val’s Co’s

aggressive and continued research and development program.
