HVAC Solenoid Valve for Refrigeration Systems
The Parker R22E52 is a normally closed refrigeration solenoid valve designed for HVAC control applications. It features a sweat ODF connection sized at 1/4 inch with a 5/32 inch port. The brass body includes a synthetic coated metal finish and carries CE, CSA, and UL certifications for safety compliance.
Upgrade from Lower-Rated or Non-Certified Valves
This valve replaces components that cannot handle a 650 psi safe working pressure or lack recognised safety listings. The jump is worth it when systems demand reliable shut-off at high pressures and regulatory approval is required for the installation. It suits technicians needing dependable flow control in demanding refrigerant circuits.
Fits Standard 1/4 Inch ODF Piping in Brass Systems
Installation requires compatible 1/4 inch ODF copper tubing for sweat connections. The brass construction integrates with similar metal piping to reduce galvanic concerns. The synthetic coating adds surface protection in typical HVAC environments. The valve frees up control logic by providing a certified, normally closed shut-off point without needing additional safety devices.

Questions about this item
What ODF connection size and port diameter does the valve use for sweat fitting?
The valve has a 1/4 inch ODF sweat connection with a 5/32 inch port diameter for refrigerant flow.
What is the correct orientation for the solenoid coil during installation?
Mount the coil vertically with the electrical conduit facing upward to prevent moisture ingress and ensure reliable operation.
How often should the synthetic coated metal seat be inspected for wear?
Inspect the seat annually or during system service; replace if leakage exceeds 0.17 degrees F superheat deviation at 650 psi working pressure.
