ARA S433 Fixed Pressure Safety Valve 3 Bar

Protects closed-loop heating and water systems with controlled pressure relief.

The ARA S433 Safety Valve is a fixed 3 Bar safety valve that protects closed heating and water systems through controlled discharge. In addition, its brass body and steel construction deliver superior corrosion resistance. Moreover, its factory calibration eliminates the need for manual adjustment.

The NBR70 gasket maximises sealing performance, while 1 1/4″ (DN32) female threaded connections suit standard industrial installations. Furthermore, the diaphragm withstands a maximum operating temperature of 110°C. When system pressure exceeds the 3 Bar limit, the valve opens automatically and discharges excess pressure in a controlled manner. The unit measures 118 mm in length and 65 mm in height.
