Safety valve, type-approved, preset and sealed, G 1/2", DN 10, 5.50 bar, brass

If the operating pressure exceeds 5.50 bar, the valve opens without external control and lets up to 261.15 m³/h escape to the atmosphere. It closes again once the pressure has dropped. The G 1/2" connection in DN 10 and the body of brass determine the installation.

Benefits

• Tested discharge capacity of 261.15 m³/h, referred to the set pressure of 5.50 bar.
• Connection thread G 1/2" at nominal size DN 10, installation with 27 mm across flats.
• FKM seal, which covers a temperature range from -25 to +180 °C.
• Overall height 75 mm and screw-in section height 14 mm, so the space required can be determined before installation.
• Body material brass, approved for compressed air and other non-toxic, non-flammable gases.

Applications

• Test benches and machines whose system pressure has to be limited to a fixed value.
• Control air circuits that are protected against pressure peaks.
• Manifolds and receivers with a G 1/2" connection.
• Installations with requirements on the resistance of the material brass.
