Aftermarket GRACO® 287545 FieldLazer Dump Valve Repair Kit, 1/4-turn valve with pin through handle (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 862635

Comparable OEM Part Number: 287545

Description: Total Finishing's part # 20-3136 is a direct-fit replacement for the pressure relief valve used in GRACO® FieldLazer and TurfLazer sprayers, the critical safety component that regulates system pressure and protects pump integrity during operation.

Spray equipment technicians and pump safety specialists rely on this valve to maintain safe operating pressures and prevent catastrophic failure in landscape and turf application equipment. When relief function degrades, system pressure can spike dangerously, compromising pump seals and forcing shutdown until service is completed.

Common reasons for replacement:

• Relief valve fails to crack at rated pressure, causing system overpressure and pump seal failure
• Valve sticks in closed position, preventing pressure regulation and triggering pressure-relief activation
• Internal wear or contamination reduces valve responsiveness, leading to creep or drift in setpoint
• Leakage past the valve seat causes pressure loss and inconsistent spray pattern during application

Manufactured to OEM-equivalent dimensions for proper fit and performance.
