Parker 77320 Coil

The Parker 77320 is a heavy-duty G23MM replacement coil engineered for high-cycle performance in Parker General Purpose (GP) Valves. Designed for field technicians who demand precision, this 208/240V AC solenoid coil operates as a normally closed (N/C) coil, providing reliable fluid and pneumatic control across automation and industrial HVACR systems. With a power rating of 9 Watts, a 30 VA inrush, and a 12 VA holding capacity, this coil ensures efficient magnetic actuation without excessive power consumption. The model G23-240 construction is built to withstand the thermal stresses of industrial environments, making it a critical component for preventive maintenance and OEM system repairs.

Key Benefits for the Contractor

• OEM Compatibility: Exact G23MM frame size ensures drop-in replacement for Parker solenoid valves, eliminating field modification.
• Voltage Versatility: Dual-rated for 208V/240V AC applications, providing flexibility for diverse commercial power supplies.
• N/C Configuration: Standard normally closed operation provides fail-safe shutoff for general-purpose fluid control.
• Efficient Power Draw: 9W wattage reduces operational heat and increases component longevity in high-demand industrial loops.

Common Technical Questions

Is the 77320 coil interchangeable with other Parker frame sizes?
No, this is a G23MM coil. Always verify the frame size on the valve body before installation to ensure the magnetic flux properly actuates the plunger.

Can this coil be used in high-moisture environments?
While the construction is durable, this coil is typically designed for standard industrial applications. If the site requires NEMA 4 or washdown ratings, please verify the housing type of your specific valve assembly.

What is the difference between the 30 VA inrush and 12 VA holding?
The 30 VA inrush is the momentary power surge required to pull the plunger into the open position, while the 12 VA holding is the continuous power needed to maintain that position, optimizing thermal efficiency.
