Safety relief valve for sealed boiler installation with rated power up to 50 kW. Safety relief temperature max. 100°C and safety relief pressure up to 0.25 MPa. The valve must not be used for steam.
Design
High lifting and soft sealing safety relief valve. Valve body made of CR-brass,
EN 12165 CW602N. Membrane of EPDM rubber.
Type approval certificates
Fitting/Installation
The safety relief valve can be installed horizontally or vertically, i.e. with the valve knob facing outwards or upwards. In horizontal installation, the outlet must be positioned so that a water pocket can not be formed. The thread has to be sealed in the usual manner.
It is easier to fit the compression fitting if lubricant is applied to the thread and bevel. Tighten first by hand and then with a spanner. Soft pipes are to be fitted with a support sleeve.
Operation/Maintenance
The safety relief valve requires no maintenance. The opening function should, however, be checked 2-3 times a year.
Turn the knob counter-clockwise by hand, until water flows out. Let the water flush through for a moment. Then turn the knob until a click is heard, about ¼ turn, and the valve returns to closed position.
