Parker Hannifin A/C Solenoid Valve

Parker Hannifin A/C Solenoid Valves: Precision Refrigerant Flow Control

When it comes to controlling refrigerant flow inside an air conditioning system, few components are as critical — or as demanding — as the solenoid valve. Parker Hannifin, a global engineering leader founded in 1918, brings its deep motion and control expertise directly to the A/C solenoid valve category, delivering components built to handle the precise, high-pressure demands of modern HVAC and automotive air conditioning systems.

Engineering Depth Behind Every Valve

Parker Hannifin's solenoid valve heritage runs through two well-regarded product families: the Sporlan Division and the Refrigerating Specialties Division, both dedicated to refrigeration and air conditioning flow control. These valves are designed to control the flow of refrigerant — whether in the liquid line, suction line, or hot gas defrost circuit — with tight tolerances and long service life. Parker's Sporlan solenoid valves, for instance, are tested and rated in accordance with A.R.I. Standard No. 760, ensuring they meet recognized industry benchmarks for capacity and performance.

A key differentiator in Parker's A/C solenoid valves is their broad refrigerant compatibility. Their refrigeration valve lineup is compatible with virtually all commercially available CFC, HCFC, and HFC refrigerants and blends, including newer low-GWP refrigerants such as R410A, R448A, R449A, and R513A. Pressure ratings reach up to 700 psi, ensuring the valves are ready for the elevated operating pressures these modern refrigerants demand.

Standout Features

• Normally closed and normally open configurations available to suit a wide variety of system designs
• High-pressure ratings engineered specifically to comply with R410A and next-generation refrigerant requirements
• Extended end sweat connections that allow brazing installation without full valve disassembly — reducing installation time and risk
• Interchangeable AC & DC coils across all valve body versions for added serviceability flexibility
• Class “F” temperature-rated coils, molded with thermoset polyester for moisture and fungus resistance in demanding under-hood and HVAC environments
• Manual stem functionality for system commissioning and emergency override
• Wide ambient operating range of -40°F to 120°F, suited for both automotive and stationary HVAC applications

Sporlan Division: A Legacy of Innovation

Parker's Sporlan Division brings over 65 years of engineering and craftsmanship in flow control devices to the refrigeration and air conditioning market. Sporlan solenoid valves are offered in both direct-acting designs (for smaller port sizes) and pilot-operated designs (for larger capacity applications), giving technicians and engineers the right tool for every system size — from small fractional-tonnage residential A/C units to large commercial installations. Innovations like synthetic seating (introduced as far back as 1947), floating disc construction, and color-coded lead wires reflect Parker's commitment to continuous product improvement.

Whether you are replacing a failed valve on a vehicle's climate control system or specifying a component for a commercial HVAC retrofit, Parker Hannifin A/C solenoid valves offer the engineering credibility and application versatility that demanding installations require.
