Safety valve, preset and lead-sealed, G 3/8", DN 10, 33.00 bar, brass

The safety valve limits the pressure in compressed air systems and opens automatically as soon as 33.00 bar is reached. In that case up to 1384.5 m³/h are discharged freely until the system pressure falls below the set value again. The valve body is made of brass and is screwed in through the G 3/8" thread in nominal size DN 10.

Benefits

• FKM seal, covering a temperature range from -25 to +180 °C.
• The material brass is admitted for compressed air and further non-toxic, non-flammable gases.
• Factory set to 33.00 bar and lead-sealed, so the set pressure is protected against unauthorised adjustment.
• At 33.00 bar the valve releases 1384.5 m³/h, a figure that applies to free discharge into the surrounding air.
• The G 3/8" thread and nominal size DN 10 suit common compressed air manifolds, spanner size 27 mm.

Applications

• Installation in systems with operating temperatures between -25 and +180 °C.
• Test benches and machines where the set pressure of 33.00 bar has to be sealed and documented.
• Protection of compressed air receivers with a permissible working pressure of 33.00 bar.

Standards and conformity

The valve is type-approved and carries the component identification TÜV.SV...-882.10.D/G.0.71 CE0036 33 bar. The marking states the notified body CE0036 and the set pressure. Delivery is exclusively with a fixed setting, fixed values between 0.2 and 50 bar are possible. A setting certificate and an NPT thread are available as options.
