Principle of Operation
Full Open Operation
When pressure in the cover chamber
is relieved to a zone of lower pres-
sure, the line pressure at the valve
inlet opens the valve, allowing full
flow.
Modulating Action
The valve holds any intermediate
position when operating pressures
are equal above and below the
diaphragm. A Cla-Val “Modulating”
Pilot Control will allow the valve to
automatically compensate for line
pressure changes.
Tight Closing Operation
When pressure from the valve inlet
is applied to the cover chamber, the
valve closes drip-tight.
• Drip-Tight, Positive Seating
• Service Without Removal From Line
• Threaded, Flanged or Grooved Ends
• Globe or Angle Pattern
• 100% Factory Tested
The Cla-Val Model 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.
The diaphragm assembly is guided top and bottom by a
precision machined stem. It utilizes a non-wicking
diaphragm of nylon fabric bonded with synthetic rubber. A
resilient synthetic rubber disc retained on three and one half
sides by a disc retainer forms a drip-tight seal with the renewable
seat when pressure is applied above the diaphragm.
The Model 100-01 is the basic valve used in nearly all
Cla-Val Automatic Control Valves. It is the valve of choice
for system applications requiring remote control, pressure
regulation, solenoid operation, rate of flow control, liquid
level control or check valve operation. The rugged simplici-
ty of design and packless construction assure a long life of
dependable, trouble-free operation. It is available in various
materials and in a full range of sizes, with either threaded,
flanged or grooved ends. Its applications are unlimited.
