Expansion Valve

Electronic Expansion Valve – RPF-AC SERIES

The RPF-AC Series Electronic Expansion Valve is designed for refrigeration and cold storage systems to accurately regulate refrigerant flow. It automatically adjusts flow to maintain stable system operation, improving cooling efficiency and energy performance. With its compact design, fast response, and reliable shut-off capability, the valve can effectively replace traditional solenoid valves, helping reduce installation space and system cost.
