Installation & Maintenance Guidelines
- Depressurize the system and isolate fluid before installing or servicing the valve to prevent fluid ejection or inadvertent flow.
- Ensure the mating threads, sealing surfaces and vent port areas are clean and free of debris or damage.
- Install the valve according to the manufacturer’s torque and alignment specifications to ensure proper sealing and vent-functionality.
- During routine maintenance, inspect for signs of leakage, ball-wear, vent-port blockage or corrosion; replace the valve if performance is compromised.
Frequently Asked Questions
It allows fluid flow control while providing a venting path for trapped air or gas, thereby reducing pressure surges and ensuring smooth system operation.
Consult your equipment’s parts diagram or service manual. If the valve listing shows “Valve, Ball, Vented – .500 – 107142”, then this is the correct replacement component.
Although the valve’s port size and thread may physically fit other systems, it is engineered to Graco’s specific pressure, sealing and venting standards. Using it outside its designated system may impact performance or warranty compliance.
Replace the valve during major system servicing if you detect venting failure, leakage, ball-wear, or if the vent feature is blocked — ensuring safe, uninterrupted operation.
Choosing the correct vented ball-valve component — the Graco 107142 Valve, Ball, Vented .500 — ensures controlled fluid flow, safe venting of trapped air and dependable long-term performance for your Graco spray, transfer or coating system.
