Parker offers a range of valves for residential and commercial air conditioning and industrial refrigeration applications. Our industrial refrigeration valves are manufactured to the highest quality standards, recognized worldwide for their performance, durability, and reliability.  

Thermostatic Expansion Valve Primarily used in the food and food preservation sector. They regulate the flow of refrigerant by maintaining a nearly constant superheat at the evaporator outlet.

Solenoid Valves Their main purpose is to automatically control the flow of fluids, liquids, or gases. Sporlan solenoid valves can be used in a wide variety of applications.

Electric Regulating Valves These are electric valves actuated by stepper motors for use in direct expansion refrigeration and air conditioning systems. Applications include Evap.

Relief Valves Designed to protect industrial and commercial refrigeration systems from overpressure situations. This series is designed to open at a specific pressure and can be used in single or dual relief configurations.  

Electronic Discharge Bypass Valves Designed for direct expansion refrigeration, air conditioning, and chiller systems, these valves control the discharge gas flow for hot gas bypass and receiver pressurization applications.

3-Way Electric Modulation Valves The 3-way modulating valve (MTW), actuated by a stepper motor, modulates refrigerant flow between two outlets to precisely control air or refrigerant temperature.

Vapor Relief Valves Designed to protect refrigeration systems from overpressure situations and features a high flow capacity. The H series is flanged for easy replacement and can be used in a single or dual relief combination.

3-Way Valves Automatically control the flow of fluids, liquids, or gases. They are used to divert refrigerant flow in heat recovery, reheat, or defrost applications.

Solenoid Coil Solenoid coils convert electrical energy into linear motion to open or close a valve. They are used in solenoid and pressure regulating valves.

Electric Regulating Valve These are electric valves actuated by stepper motors for use in direct expansion refrigeration and air conditioning systems. Applications include Evap.

Isolation Ball Valve Designed for use in air conditioning and refrigeration units. They ensure positive shut-off refrigerant flow in either direction of flow, even during system evacuation.

Electric Valve Parker-Sporlan electric valves are electric expansion valves actuated by a stepper motor designed for use in direct expansion refrigeration and air conditioning applications.

Manual Shut-off/Expansion Valves RS shut-off/expansion valves were designed and manufactured to maintain reliability in both their seating and back seating functions.

Drain Ball Valve These are valves that have a spring return handle and are available in stainless steel or carbon steel.

Gauge Valve Tiny, robust, steel-bodied manual valves are designed to seat tightly and allow for the isolation of small system components. They are primarily used as gauge (V2) and drain (V3) valves.

Refrigerant Modulating Valve The MVS industrial electronic control valve uses electronic controls to regulate liquid and vapor refrigerant flows.

Check Valves CK4A type check valves prevent fluid backflow in refrigerant suction, hot gas, or liquid lines.

Gas Suction Stop Valve The S9A and S9W valves are designed to open or close quickly and completely under conditions that render conventional solenoid valves unreliable or unsuitable. The S9 does not require a minimum pressure drop to open, making it ideal for certain applications.
