Safety valve, type-approved, preset and sealed, G 3/4", DN 10, 14.00 bar, stainless steel 1.4571

If the operating pressure exceeds 14.00 bar, the valve opens without external control and lets up to 608.3 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

• Tested discharge capacity of 608.3 m³/h, referred to the set pressure of 14.00 bar.
• Connection thread G 3/4" at nominal size DN 10, installation with 32 mm across flats.
• FKM seal, which covers a temperature range from -25 to +180 °C.
• Overall height 95 mm and screw-in section height 16 mm, so the space required can be determined before installation.
• Body material stainless steel 1.4571, approved for compressed air and other non-toxic, non-flammable gases.

Applications

• Compressor stations and compressed air treatment up to an operating pressure of 14.00 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.
