Parker 78033 Coil

The Parker 78033 Coil, model H-23R, is a high-performance solenoid replacement coil designed for critical refrigeration and air conditioning applications. Operating at 220/240V 50/60Hz with a 9.5W power consumption, this industrial solenoid coil provides the reliable magnetic force required to actuate refrigerant valves in demanding environments. Built with Class F insulation or higher, the Parker H-23R 220V coil is engineered to withstand high ambient temperatures and rapid cycling without thermal degradation, ensuring long-term stability in HVACR systems. This coil is frequently utilized in Jackes Evans solenoid valves and various reversing valve configurations. Its encapsulated design offers superior protection against moisture and vibration, making it a standard choice for technicians seeking a rugged 240V solenoid coil for field repairs or system upgrades. Accurate voltage matching is essential to prevent coil burnout and maintain optimal MOPD performance across the valve seat.

• Optimized Power Draw: The 9.5W energy efficiency minimizes heat generation while providing consistent pull-in and holding force.
• Dual Frequency Compatibility: Engineered for 50/60Hz operation, facilitating seamless integration into various international HVACR 220V power supplies.
• Environmental Resilience: Features a robust, epoxy-encapsulated housing to prevent electrical shorts caused by condensate or industrial contaminants.
• Direct OEM Fit: Drop-in 78033 solenoid replacement for Jackes Evans and Parker assemblies, reducing downtime during emergency service calls.

Is the Parker 78033 compatible with 208V systems?
While often utilized in similar environments, this coil is specifically rated for 220/240V. To prevent premature failure or weak magnetic actuation, always verify the supply voltage matches the H-23R technical specifications.

Can this coil be used on liquid line solenoid valves?
Yes, the Parker H-23R is commonly found on liquid line and suction line solenoid valves, provided the valve stem dimensions match the internal diameter of the coil housing.

What causes a Parker 78033 coil to burn out?
Common causes include incorrect voltage, moisture ingress at terminal connections, or a stuck valve plunger (mechanical stall) which leads to excessive amperage draw through the windings.
