The Solenoid Valves & Pressure Switches category includes the control and safety devices that manage refrigerant flow and protect compressors in HVAC/R systems. Solenoid valves provide on/off control of liquid and gas flow, while pressure switches monitor suction and discharge conditions to prevent damage and maintain stable operation.
Here you’ll find liquid line and hot-gas solenoid valves, normally closed and normally open valves, pilot-operated and direct-acting designs, low- and high-pressure switches, dual pressure controls, oil safety controls and fan cycling switches. These components are used on split systems, heat pumps, walk-in coolers, ice machines, reach-ins, rack systems and low-temp refrigeration.
When selecting solenoid valves and pressure switches, verify refrigerant type, MOPD/working pressure, voltage and coil type, pipe size and connection style, flow direction, pressure range and electrical rating. Matching these components to system design is essential for reliable pump-down, defrost, head pressure control and compressor safety.
Pro tip: Always install a filter drier upstream of solenoid valves and keep pressure switch sensing lines short and properly supported. Debris and vibration are common causes of nuisance failures and callbacks.
