A flow shut off or throttling valve is provided in a sprinkler nozzle housing to enable a nozzle to be changed without having to turn off a flow pressure source. The valve intersects a flow path through the nozzle housing and has an opening such that when the opening is aligned with the ...
spray sprinkler equipped with a flow shut off valve. However, the shut off valve is relatively high in the flow conduit. Therefore, if the flow conduit is cut or broken at a point at or below the shut off valve, water will flow from the conduit, and the shut off valve will not ...
The sprinkler valve has two pipes connected to it: the inlet and the outlet. The inlet pipe brings water from the household supply to the valve. The inlet ends in the middle of the valve with a stopper called a diaphragm, which is held in place with a rod and a spring which are ...
A valve for pressurized, liquid sprinkler systems which is adapted for flowesting of the valve without activating the sprinkler system. The valve is constructed with a valve body having a fluid inlet and a fluid outlet connected by a flow passage. The fluid inlet is provided with a supply of...
With most systems, several valves are involved, each controlling a different circuit, or series, or sprinkler heads. Sprinkler valves may be controlled manually at the valve or remotely by a timer, connected by electrical wires to the valve. Most timers are designed to control several valves ...
areas to create force for any non-zero pressure through the valve. This feature, in conjunction with momentary fluid flow in the solenoid circuit, is responsible for complete regulation of the flow characteristics of the valve. The requirement for large shut-off springs and flow control adjustment...
