A high-quality normally open solenoid valve is open in its de-energized state. There are various designs, but a basic design has the armature positioned high up in the coil. So when the valve energizes, the armature is pulled down towards the center of the coil. A plunger or piston attached to the armature moves down, closing the valve. When the valve is again de-energized, a spring pushes the armature back up, opening the valve. A normally closed solenoid valve is typically used for emergency safety to stop the flow of media. However, if a pressure-build up is the emergency concern, then a normally open solenoid valve should be used.
SANHENG Normally Open Refrigeration Solenoid Valve manufacturers in China. This solenoid valve is a two-position two-normally open solenoid valve. The valve opens when the power is off and closes when the power is on. It is widely used in automatic control of refrigeration, pneumatic and hydraulic systems. This series of solenoid valves are the solenoid valves with lead diaphragm structure. The solenoid valves adopt all-plastic encapsulated solenoid coils, which have excellent insulation, waterproof, seismic and corrosion resistance.
SANHENG Large Body Normally Close Refrigeration Solenoid Valve manufacturers in China. In the refrigeration system, the solenoid valve is the key component to control the fluid on and off. This kind of solenoid valve is widely used in refrigeration units, central air conditioning, refrigeration equipment and bus air conditioning and other refrigeration systems. In these applications, the stable performance of the solenoid valve is essential to ensure the proper operation of the system. The new refrigeration solenoid valve adopts high-quality materials and advanced production technology, has strong durability and reliability, and can maintain good performance during long-term use.
