Parker 77340 Coil

The Parker 77340 Solenoid Coil is an industrial-grade 480V N/C coil engineered for high-demand HVACR and hydronic applications. Designed as a direct replacement part, this G23MM coil features a normally closed configuration, ensuring fail-safe operation in general-purpose valve systems. With 9 watts of power consumption and a 12 VA holding rating, it provides stable electromagnetic force to maintain valve positioning under continuous duty. The 30 VA inrush capacity enables crisp actuation, even in systems with fluctuating pressure differentials. The encapsulated G23-480 solenoid coil housing is built to withstand the thermal stress and vibrational demands typical of industrial mechanical rooms. This genuine Parker-Jackes Evans component ensures seamless compatibility with GP series valves, maintaining the precise flow control and pressure ratings required for heavy-commercial electrical circuits. Its compact design facilitates straightforward installation within standard solenoid housings, minimizing downtime during field service.

Key Benefits:

• High-Voltage Precision: Optimized for 480V 60Hz systems commonly found in industrial and heavy-commercial HVAC environments.
• Fail-Safe Logic: Normally closed (N/C) design ensures the valve returns to its closed state upon loss of power for enhanced system safety.
• Energy Efficient Performance: Low 9-watt operating power reduces heat buildup and energy consumption during long-term operation.
• Rugged Build Quality: Durable coil winding and encapsulation protect against moisture and environmental contaminants.
• Universal GP Compatibility: Designed specifically for Parker G23 series general-purpose valves to ensure a precise mechanical fit.

Common Questions:

Is this coil compatible with 240V systems?
No, the Parker 77340 is specifically wound for 480VAC operation. Installing this on a lower voltage system will result in insufficient electromagnetic force to lift the plunger, while higher voltage will cause immediate coil burnout.

Can I use this on a Normally Open (N/O) valve?
This 480V solenoid coil is designed for normally closed valve configurations. Using it on an N/O valve body may result in improper mechanical operation or seating issues due to the internal spring tension and plunger stroke differences.

Does this include the valve body?
This part number refers to the replacement solenoid coil only. It is intended for field service where the mechanical valve body remains intact but the electrical actuator requires replacement.
