Product Name: Freon solenoid valve high pressure solenoid valve Introduction SV series two ways normal closed solenoid valve with diaphragms can be widely used in refrigeration, pneumatic and hydraulic system, also in boiler and fire-fighting, etc. 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 diaphrgm through throttle hole, then pressure in both side of diaphragm balances, then the diaphragm will drop and close the main orifice. Usage 1. The valve must install in horizontal pipe line under vertical position. The flow direction must meet the arrow direction in valve body. 2. The oil input voltage must meet rated input voltage showed on the label. Departure coil from valve when energized in coil is not permitted in order to avoid damage the coil. 3. According to valve with manual function, it must turn manual bar to open the valve before doing system air tightness in order to avoid to damage diaphram. 4. When brazing the valve with connect tube in system, follow points are very important: a. Before brazing, coil must be departure and use wet fabric cover the valve body to avoid to damage valve part because of high temperature when brazing. b. It must avoid the brazing flame face to valve body. c. It is better to adopt low temperature type silver brazing bar. 5. According to valve with manual function. The manual bar must be turned to open the valve before doing system air tightness, in order to avoid to damage the diaphram. 6. Coil must be set to the body when the current on. Technical data cheap
