Reneka boiler safety valve 1/2"M

The Reneka Boiler Safety Valve 1/2"M is used to release pressure within the Boiler to maintain the proper ratio of heat and volume of water in the tank. It's a safety mechanism and limits the coffee pressure.

One of the major factors which control the quality of your espresso is the pressure with which the water is delivered to the coffee. The Boiler Safety Valve is responsible for keeping the pressure from exceeding a predetermined level. Most espresso machines control pressure by using this simple Boiler Safety Valve. Also, this part may be referred to as a Pressure Relief Valve or Over-Pressure Valve.

The Pressurestat and scale build-up are normally the cause for the damage to the Boiler Safety Valve. The spring will become weak with years of pressure pushing against it and eventually it will start to leak. If you hear a slow hissing and/or see water dripping from the pressure relief valve, it is time to change the Boiler Safety Valve.
