Safety valve, type-approved, preset and sealed, G 3/4", DN 10, 34.50 bar, brass

If the operating pressure exceeds 34.50 bar, the valve opens without external control and lets up to 1445.8 m³/h escape to the atmosphere. It closes again once the pressure has dropped. The G 3/4" connection in DN 10 and the body of brass determine the installation.

Benefits

• Free-blowing design without collecting line, the 1445.8 m³/h are released directly to the atmosphere.
• Self-acting operation without auxiliary power, the valve recloses once the pressure has fallen below 34.50 bar.
• Fixed setting at 34.50 bar and lead-sealed, so the set pressure is protected against unauthorised adjustment.
• Tested discharge capacity of 1445.8 m³/h, referred to the set pressure of 34.50 bar.
• Connection thread G 3/4" at nominal size DN 10, installation with 32 mm across flats.

Applications

• Compressor stations and compressed air treatment up to an operating pressure of 34.50 bar.
• Supply lines for non-toxic and non-flammable gases.
• Test benches and machines whose system pressure has to be limited to a fixed value.
• Control air circuits that are protected against pressure peaks.

Standards and conformity

The valve is type-tested and carries the component marking TÜV.SV...-882.10.D/G.0.71 CE0036 34.5 bar. Only the factory set and lead-sealed version is supplied, the set value of this article is 34.50 bar. Fixed settings between 0.2 and 50 bar are available from the manufacturer.
