BODY INTRODUCTION
The Cla-Val Deluge 800 Series Valve is a pressure operated in-line
axial valve. It is actuated by a tube diaphragm. It is comprised of 3
major components; Tube 1, Barrier 2 and Body 3.
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.
Forty p.s.i. inlet pressure is the minimum recommended operating
pressure.
Maximum pressure rating for deluge service is 250 p.s.i. (See ANSI
std. B-16.5).
The tube diaphragm is a one piece homogeneous nitrile rubber part,
which is extremely durable. The ends of the tube are thick solid rub-
ber designed to fit between mating flanges. This design eliminates
the possibility of cutting the tube diaphragm due to over tightening or
piping misalignment during installation.
CLOSED
Water pressure (equal to inlet pressure) from valve
inlet is applied to the control chamber. Valve closes
bubble tight.
OPEN
When pressure in the control chamber is
relieved the valve opens.
FLOW
Note: Each valve is equipped with items indicated on drawings listed on page 3.
The adjustable pressure switch has single pole double throw contacts.
See data sheets for pressure switch and solenoid operated valve.
