CLA-VAL 100-01 Main Valve HYTROL Simple, Reliable and Accurate Main Function The CLA-VAL Model 100-01 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.

Valve Closure
When pressure in the cover chamber is relieved to a lower pressure or to the atmosphere, the inlet pressure opens the valve.
When inlet pressure is applied to the cover chamber, the valve closes drip-tight.
A Cla -Val “modulating” pilot control is fitted to automatically compensate for line pressure changes.

CLA-VAL 60-32 / 660-32 Pump Control & Back Pressure Valve Simple, Reliable and Accurate The CLA-VAL SERIES 60/660 Pump Control Valve is a pilot operated valve designed for installation on the discharge of pumps to prevent pipeline surges caused by the starting and stopping of pumps. Features and Benefits ü Automatic Operation ü Easy Adjustment and Maintenance ü Unparalleled Technical Support
CLA-VAL 60-31/660-31 : Operation Pump off When the pump is off a hydraulic check feature keeps the valve in the closed position. Starting sequence 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.
CLA-VAL SERIES 50/650 : Main Function (sustaining) Pressure relief valve or surge anticipator valve
Stopping sequence 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.

CLA-VAL 100-42 700 Series Roll Seal Simple, Reliable and Accurate The Cla-Val Model 100-42 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.

CONTROL CHAMBER
Model 100-42 Valve in Closed Position Upstream pressure is introduced to the control chamber (the chamber formed behind the liner) of the Cla-Val Model 10042 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.
Model 100-42 Valve in Partially Open Position 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.

Model 100-42 Valve in Fully Open Position 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.

WHY SPECIFY CLA-VAL AUTOMATIC CONTROL VALVES? TM
INTRODUCTION 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. THE CLA-VAL DIFFERENCE Low Flow Conditions 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. Resistance to Cavitation Damage 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. High Differential Pressure 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. Sensitive and Critical Flow and Pressure set Points 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. Ease of Maintenance 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 Local Manufacture 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.
