314 Safety relief valves for heating and hot water systems
Safety relief valves are typically used for controlling pressure on boilers in heating systems, on stored hot water cylinders in domestic hot water systems and in water systems generally. When the calibrated pressure is reached, the valve opens, and, by means of the discharge to atmosphere, prevents the pressure of the system from reaching levels which would be dangerous for the boiler and the components in the system itself.
Our 314 series safety relief valve is set to 3 bar and comes with ½“ male iron threads and a blank pressure gauge port. The pressure gauge port can be used to easily attach our WI-557 pressure gauge if required.
The video below is for the 311 and 312 series which is the same as the 314 but without the pressure gauge port:
