The Single solenoid control valve is considered to be an ON/OFF valve. A normally (open – close) solenoid controls the paths of water through the pilot tube, either by tripping the water inside the valve’s bonnet chamber or releasing it out. Normally this solenoid depends on a controller signal to open or close generally according to a certain level of a tank
The model 1100/S Pressure Reducing Valve is a hydrauli-cally operated, diaphragm actuated, control valve that reduces higher upstream pressure to lower constant downstream pressure regardless of ﬂuctuating demand or varying upstream pressure, Thanks to a Sole-noid Control, the Valve will also open or close in response to a signal
Sierra water air valve series 6400-PP Are Hydromechanical devices designed to automatically release or admit air during pipeline filling, draining, or operation of a water pipeline or system. The safe operation and efficiency of a pipeline are dependent on the continual removal of air from the pipeline.
The model 2400 is a pressure management valve that reduces high line pressures to lower distribution system levels, as it can switch between two pilots by means of a latching solenoid. The solenoid control feature can be activated by an electrical signal from a battery-operated controller.
