Basic Info

Model No.: SV-G

Product Description Specifications SV-G series Solenoid Valves can be used as actor of automatic system in water supply system,fire control system, etc

solenoid valves  Water Valves  SV-G series internal thread    :   SV-G series solenoid valves can be used as actor of automatic system in water supply system, fire control system, and water spray system in dirty proofing or agricultural. They also can be used for pneumatic hydraulic and food machine.
Solenoid valves use full-closed magnetic coil and DIN international standard electric plug, so it is characterized by its good insulation, waterproof, moisture proof, anti-vibration and corrosion resistance. Operating principle
While energized in coil, the electromagnetic power opens the small orifice. Then the pressure in upside of valve reduced, so the pressure difference between both side of diaphragm happen and lead to diaphragm lift to open the main orifice. While de-energized in the coil, plug stem will drop and close the small orifice because of spring force and its weight. The flow media enters into upside of diaphragm through throttle hole, then pressure in both side of diaphragm balances, then the diaphragm will drop and close the main orifice. Technical data
