The Cla-Val Model 800GS Deluge Valve is a pressure operated, in-
line axial valve. A tube diaphragm actuates the valve, which is com-
prised of three major components: 1) Tube 2) Barrier and 3) Body.
There is only one moving part in the valve - the tube diaphragm.
There are no shafts, packing, stem guides or springs.
The tube diaphragm is a one piece, homogeneous nitrile rubber part
which is extremely durable. The ends of the tube are thick solid rubber,
designed to fit between mating flanges. This design eliminates the
possibility of cutting the tube diaphragm due to overtightening or pip-
ing misalignment during installation.
The tube forms a drip tight seal around the barrier when the pressure
is equalized between the valve inlet and the control chamber. When
pressure is removed from the control chamber, the valve is open. The
minimum recommended operating pressure is 40 P.S.I. of inlet pressure.
Principle of Operation
Full Open Operation
When pressure in control chamber
is relieved, the valve is open.
Tight Closing Operation
Water pressure from valve inlet is
applied to the control chamber. Valve
closes bubble tight.
