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.
