`Operating data
1.1 `PRESURE REDUCING FEATURE
Pressure reducing control (5) is a "normally open" control that senses main valve (1) outlet pressure changes. An increase in
outlet pressure tends to close control (5) and a decrease in outlet pressure tends to open control (5). This causes main valve
cover pressure to vary and the main valve (1) to modulate (open and close) maintaining a relatively constant outlet pressure.
Pressure reducing control (5) adjustment: Turn the adjusting screw clockwise to increase the setting.
1.2 `OPENING SPEED CONTROL
Flow control (4) regulates the opening speed of main valve (1).
Flow control (4) adjustment: Turn the adjusting screw clockwise to make the main valve open more slowly.
1.3 `(E*) EUROPEAN STANDARDS
ITEM (2) - Isolation ball valve:
The isolation ball valves are used to isolate the pilot system from main line pressure. These isolation ball valves must be
open during normal operation.
ITEM (3) - Y-Strainer with incorporated orifice:
The strainer is installed in the pilot supply line to protect the pilot system from foreign particles. The strainer screen must be
cleaned periodically.
1.4 `OPTIONAL FEATURES
Suffix (A) - Internal strainer self-cleaning:
In some applications the self-cleaning strainer CLA-VAL, type X46A screwed at the inlet of main valve (1) reduces
maintenance generated by the cleaning of the standard strainer screen (3).
With this option (A) the strainer X46A replaces the strainer (3) and the orifice of the X44A strainer (3) is replaced by the
orifice assembly X58-CSA.
The cleaning of the strainer X46A is requesting its removal from the main valve body (1).
Suffix (C) - Closing speed:
Flow control (C) regulates the closing speed of main valve (1).
Flow control (C) adjustment: Turn the adjusting screw clockwise to make the valve close more slowly.
Suffix (Y) - High capacity filter:
When too many foreign particles are contained into the control pressure, it is recommended to replace the standard filter
X44 by the high capacity filter X43/80-EP, whose screen (Ø 80 mm x 110 mm) offers a much bigger filtration surface.
However an additional union fitting, with incorporated calibrated orifice, model X52-VR must be mounted between the filter
outlet and the T-piece connecting the main valve control chamber.
1.5 `CHECK LIST FOR PROPER OPERATION
□System valves open upstream and downstream.
□Air removed from the main valve cover and pilot system at all high points.
□Isolation valves (2A), (2B) and (2C) open.
□Periodical cleaning of the filter screen (3) or of the self-cleaning strainer, [optional feature (A)].

Main Valve HYTROL
`CLA-VAL Europe www.cla-val.ch [email protected] 1-HYN001DE B 01/08
`Simple, Reliable and Accurate
`CLA-VAL SERIES 100 Main Function
The CLA-VAL 100-01 HYTROL Valve is a
hydraulically operated, diaphragm actuated, globe
or angle pattern valve.
It consists of three major components: 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 100-01 is the basic valve used in
nearly in all CLA-VAL Automatic Control Valves.
`CLA-VAL 100-01 Principle of Operation
Full Open Operation:
When pressure in the cover
chamber is relieved to a lower
pressure or to atmosphere, the
pressure inlet opens the valve.
Tight Closing Operation:
When pressure from the inlet
pressure is applied to the cover
chamber, the valve closes drip-tight.
Modulating Control:
The valve is pressure operating
balanced. The CLA-VAL
"Modulating" Controls will allow the
valve to automatically compensate
for pressure changes.

`DESCRIPTION
The CLA-VAL Model 100-01 HYTROL Valve is a main
valve for CLA-VAL Automatic Control Valves. It is a
hydraulically operated, diaphragm-actuated, globe or
angle pattern valve.
This valve consists of three major components; body,
diaphragm assembly, and cover. The diaphragm
assembly is the only moving part. The diaphragm
assembly uses a diaphragm of nylon fabric bonded with
synthetic rubber. A synthetic rubber disc, contained on
three and one half sides by a disc retainer and disc guide,
forms a seal with the valve seat when pressure is applied
above the diaphragm. The diaphragm assembly forms a
sealed chamber in the upper portion of the valve,
separating operating pressure from line pressure. Illustration type GE
`INSTALLATION
1. Before valve is installed, pipe lines should be flushed of all chips, scale and foreign matter.
2. It is recommended that either gate or block valves be installed on both ends of the 100-01 HYTROL Valve to facilitate
isolating the valve for preventive maintenance and repairs.
3. Place the valve in the line with flow through the valve in the direction indicated on the inlet nameplate. (See “Flow
Direction” Section)
4. Allow sufficient room around valve to make adjustments and for disassembly.
5. CLA-VAL 100-01 HYTROL Valves operate with maximum efficiency when mounted in horizontal piping with the cover
UP, however, other positions are acceptable. Due to size and weight of the cover and internal components of 8 inch and
larger valves, installation with the cover UP is advisable. This makes internal parts readily accessible for periodic
inspection.
6. Caution must be taken in the installation of this valve to insure that galvanic and/or electrolytic action does not take
place. The proper use of dielectric fittings and gaskets are required in all systems using dissimilar metals.
7. If a pilot control system is installed on the 100-01 HYTROL Valve, use care to prevent damage. If it is necessary to
remove fittings or components, be sure they are kept clean and replaced exactly as they were.
8. After the valve is installed and the system is first pressurized, vent air from the cover chamber and pilot system tubing by
loosening fittings at all high points.
`FLOW DIRECTION
The flow through the 100-01 HYTROL Valve can be in one of two directions. When flow is “up-and-over the seat,” it is in
“normal” flow and the valve will fail in the open position. When flow is “over the seat-and down,” it is in “reverse” flow and the
valve will fail in the closed position. There are no permanent flow arrow markings.
The valve must be installed according to nameplate data.
BRIDGEWALL INDICATOR
(cast into side of valve body)
`RECOMMENDED TOOLS
1. Three pressure gauges with ranges suitable to the installation to be put at HYTROL inlet, outlet and cover connections.
2. CLA-VAL Model X101 Valve Position Indicator. This provides visual indication of valve position without disassembly of
valve.
3. Other items are: suitable hand tools such as screwdrivers, wrenches, etc. soft jawed (brass or aluminum) vise 400 grit
wet or dry sandpaper and water for cleaning.
