A pressure relief valve that helps to protect equipment in pressurised water systems onboard by relieving pressure if it is greater than the system requires.
Pressure relief valves act as a safe guard to pressurised water systems. Relief valves help to protect the more expensive equipment that can be found in pressurised water systems onboard by relieving pressure if it is greater than the system requires.
A pressure relief valve is design to open at a particular pressure as a protection for equipment that may not be built for an increase in pressure, for example, a boats water calorifier.
It is important to determine the water system pressure before installing a new pressure relief valve.
