Product Description Specifications Solenoid Valve two ways mormal closed Solenoid Valves with diaphragms can be widely used in refrigeration

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, the valve flows bi-directionally. While de-energized in the coil, plug stem will drop and close the small orifice because of spring force and its weight. When inlet pressure is higher than outlet pressure across valve, the valve closed. When outlet pressure is higher than inlet pressure across valve, a few medium can flow across the valve in opposite direction. Technical data

The Kv value is the water flow in m3/h at a pressure drop across valve of 0.1MPa,ρ=1000 kg/m3 Letters after the model: A means improved type,W means solder ODF,F means waist flange,K means normal opened valves.
