Parker 76738 Repair Kit

The Parker 76738 GP1057 Repair Kit is a critical maintenance component designed for servicing high-performance solenoid valves within commercial refrigeration and HVAC systems. This Parker solenoid valve rebuild kit provides the necessary internals to restore pressure regulation and prevent leakage at the seat, ensuring the assembly maintains its original MOPD ratings. Specifically engineered for compatibility with Parker Hannifin vapor or liquid line regulators, the kit addresses common failure points such as worn diaphragms or compromised gaskets that lead to system inefficiency or pressure drop issues. Utilizing an OEM refrigeration repair kit is essential for maintaining the integrity of the mechanical cooling cycle and preventing refrigerant migration. When executing a solenoid valve diaphragm replacement, technicians should verify the seat disc and plunger assembly for any debris or scoring before reassembling the valve body. This kit simplifies the HVAC valve maintenance process, reducing downtime and ensuring the system operates within precise pressure and temperature specifications.

• Ensures hermetic sealing to prevent refrigerant bypass and maintain system head pressure.
• Includes high-grade elastomers and internal components resistant to synthetic oils and high-pressure refrigerants.
• Restores solenoid actuation efficiency, reducing the risk of valve sticking or failure to close under load.
• Designed for precise fitment in GP1057 series valves to eliminate the need for complete valve replacement.

What are the signs that a solenoid valve requires a repair kit?
Technicians typically identify failure through audible clicking without valve opening, external leaks around the bonnet, or refrigerant migration during the off-cycle, indicating the internal seal or diaphragm has failed.

Is this kit compatible with all Parker solenoid valves?
No, the 76738 GP1057 kit is specific to certain valve body sizes and series. Always cross-reference the model number on the valve nameplate to ensure internal tolerances and seat configurations match.

Does this kit include the replacement coil?
This rebuild kit focuses on the internal mechanical components and seals. If the issue is electrical, such as an open or shorted solenoid coil, that component must be sourced separately.
