Features: Spring adjustment range from 0.5 to 40 bar, ensuring complete watertightness and preventing manipulation.

3. Open Discharge Safety Valve (Fig. V69.01):

Materials: Made from brass-bronze with a metal seat.
Pressure and Temperature: Maximum working pressure of 30 bar, temperature limits from -10°C to 220°C.
Features: Direct spring actuation, male threaded connection, suitable for non-toxic or corrosive gases, includes a hexagonal cap and soft seat for sealing.

Installation Guidelines:

Ensure cleanliness of inlet and outlet connections to prevent impurities.
Install valves vertically and consider backpressure during selection.
Avoid using sealing joints that release waste and ensure compliance with local legislation.

Packaging and Optional Services:

Valves are delivered with protective caps to prevent internal damage and dust ingress.
Optional services include factory rating, sealing, EC compliance certification, and monitoring sensors.

V70 Series Safety Valves:

Specifications: Enclosed discharge with male x female threaded connections and an actuating lever. Suitable for various fluids, with a spring adjusting range from 0.5 to 30 bar and temperature limits from -10ºC to 180ºC.
