Solenoid and Ball Valve
Products
The RSDF series solenoid valves are designed for precise refrigerant flow control in refrigeration, cold storage, air-conditioning, and heat pump systems. Available in both direct-acting and pilot-operated types, these valves ensure reliable automatic operation and efficient system performance. Featuring a low-power consumption coil and high reliability, the RSDF series provides excellent opening performance with a large allowable pressure differential. Built to handle demanding environments, the valves support various refrigerants and operate across a wide temperature range, making them a dependable solution for modern HVAC and refrigeration applications.
