Water Control Valve Application Examples
A: Pressure Reducing Valve, Reduces pressure to a distribution system when gravity fed from a source with a relatively high elevation.
B: Pressure Reducing Valve,Reduces pressure in an irrigation system.
C: Pressure Reducing Valve,Maintains a preset upstream pressure and a preset downstream pressure reduction.
D: Pressure Reducing Valve, Reduces pressure to a low pressure zone when the pump discharge is too high.
E: Back Pressure Valve,Prevents over pumping of both deep well and booster pumps if the system demand exceeds the pumping capacity.
F: Pressure Reducing Valve,Guarantees maintenance of sufficient upstream pressure when supplying water to a low pressure zone.
G: Back Pressure Valve,Prevents a pump from lowering its suction pressure below a desired safe operating minimum.
H: Constant Differential Pressure,Maintains a constant differential pressure across a pump to maintain a constant flow rate.
|: Back Pressure Valve, Protects the system against accidental over pressures (caused by a failure of the control valve C100. stop valve closing too quickly).
J: Altitude valve, Double action altitude valve allowing filling of the tank and emptying back to the supply.
K: Float Valve, Controls the level of the tank by means of float regulation and allows distribution to the village.
L: Water- Hammer Arrestor, Protects the pump station against surges due to start up, shut down and power failure.
MN: Electric Pump Protection, Eliminates pressure fluctuations when pump starts and shuts down.
O:Flow Limiter, Controls flow rate to the factory.
P: Back Pressure Valve, ON/OF Electrically Controlled, Allows flow between two distribution systems (example : feeding a water storage tank for peak distribution time).
Q: Air Release Valve, Allows the release of air in excess in clear water piping systems.
R: Water-Hammer Arrestor , Absorbs water hammering.
S: Air Release Valve, Allows the release of air in excess in waste water systems.
