    • Product Details
      Pressure Relief Valves also sometimes known as safety release valves, expansion relief valves or prv’s are in place to prevent a dangerous build-up of system pressure. They are commonly used in most domestic properties and can be found on boilers and unvented cylinders. The valves are designed to open up to release the pressure when the level becomes too high, and close again when the pressure has dropped to within a safe range. All manufacturers of boilers, unvented cylinders, and other types of pressurised water heaters will advise that all safety control devices including pressure relief valves should be annually maintained and serviced and replaced immediately if they are damaged or do not operate as they are intended to. There are many different types of valves that all work in different ways but are still able to maintain the pressure in a system effectively. As the pressure builds, the spring is able to control the valve by not allowing the pressure of the hot water to pass through, however as the force applied becomes greater than the force the spring can withhold, the spring moves to release the valve. Once this valve is opened, the water is able to pass through, as the pressure drops, the spring is able to apply enough downward force to reseal the valve. Pressure Relief Valves are set to a specific pressure to ensure maximum safety for you and your system, whilst you can find pressure relief valves with adjustable pressure settings it is recommended that on a pressurised system the valve is to be set to the manufacturers recommended pressure and should not differ from this unless the manufacturer recommends doing so.
