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.

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).

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.

The CLA-VAL 50-01/650-01 (Sustaining Service) is
typically installed in a line between an upper zone and a
lower area of heavy demand or tank, the valve acts to
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 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.

700 Series Roll Seal
Simple, Reliable and AccurateSimple, Reliable and Accurate

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.
