🔌 Function

⚠️ Common Signs of Failure

• The valve sticks, binds or fails to seat correctly
• Pressure or flow in the associated circuit moves outside specification
• Internal leakage causes unstable or reduced system performance
• Contamination, corrosion or wear is visible on the valve surfaces
• The engine develops starting, power, temperature or pressure-control symptoms

🛠️ Service Notes

• Work clean — a valve is a precision component, and dirt or swarf carried in on the sealing faces is the commonest reason a new one fails early
• Fit new sealing rings, gaskets or washers wherever the original used them rather than reusing the old ones, and lubricate them lightly so they seat without rolling or nipping
• Check the seat, bore or housing the valve fits into for corrosion, scoring or distortion; a valve only seals as well as the face it beds on
• Tighten fixings and threaded connections to the figures and in the order given in the workshop manual for your engine — a valve body is easily distorted by overtightening
• After fitting, bleed or refill the system as required, then run the engine and check the valve for leaks and for correct operation before the boat is used
