Safety valve, type-approved, preset and sealed, G 3/4", DN 10, 15.00 bar, stainless steel 1.4571

If the operating pressure exceeds 15.00 bar, the valve opens without external control and lets up to 649.2 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 stainless steel 1.4571 determine the installation.

Benefits

• Free-blowing design without collecting line, the 649.2 m³/h are released directly to the atmosphere.
• Self-acting operation without auxiliary power, the valve recloses once the pressure has fallen below 15.00 bar.
• Fixed setting at 15.00 bar and lead-sealed, so the set pressure is protected against unauthorised adjustment.
• Tested discharge capacity of 649.2 m³/h, referred to the set pressure of 15.00 bar.
• Connection thread G 3/4" at nominal size DN 10, installation with 32 mm across flats.

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 3/4" connection.
• Installations with requirements on the resistance of the material stainless steel 1.4571.
