Solenoid Valve with Diaphragms
Description
The SV series solenoid valve is a two way, closed solenoid valve, or a normal open solenoid valve with diaphragms. They are widely used in refrigeration, pneumatic and hydraulic systems, boilers and firefighting. Solenoid valves use a fully closed magnetic coil and DIN international standard electric plugs, ensuring an excellent insulation, waterproof performance, moisture resistant performance, vibration resistance and corrosion resistance.
Operating Principle
While energizing in the coil, electromagnetic power powers a small opening. The pressure on the upside of the valve is reduced, thus, a pressure difference between both sides of the diaphragm occurs and leads to the diaphragm lifting in the main opening. When the coil loses energy, the plug stem will drop and close the opening, due to the spring force and its weight. The flow media enters the upside of the diaphragm through a throttle hole, thus balancing the pressure on both sides of the diaphragm. Once the pressure balances, the diaphragm will drop and close the main opening.
Advantages
1. Various types of solenoid valves are available: diaphragm, piston, two way bi-flow valves and more
2. They are widely used in refrigeration, pneumatic and hydraulic systems, boilers and firefighting.
3. Excellent insulation, water and moisture resistant, vibration resistant, corrosion resistant
4. These valves use a fully enclosed magnetic coil and DIN international standard electric plug
5. Certificates: ISO, CQC, CE, DNV and others
