Safety valve, preset and lead-sealed, G 3/4", DN 10, 31.00 bar, stainless steel 1.4571

To protect compressed air and other non-toxic, non-flammable gases, this valve opens at 31.00 bar. Up to 1302.7 m³/h are released freely into the surrounding air. The G 3/4" thread, nominal size DN 10 and the material stainless steel 1.4571 determine the installation.

Benefits

• The G 3/4" thread and nominal size DN 10 suit common compressed air manifolds, spanner size 32 mm.
• Overall height H of 95 mm and height h of 16 mm, so the space required is known before installation.
• The FKM sealing material allows operating temperatures from -25 to +180 °C.
• Factory set to 31.00 bar and lead-sealed, so the set pressure is protected against unauthorised adjustment.
• At 31.00 bar the valve releases 1302.7 m³/h, a figure that applies to free discharge into the surrounding air.

Technical data

Applications

• Protection of pipes and fittings in compressed air networks with a G 3/4" connection.

• Protection of gas lines carrying non-toxic, non-flammable gases up to 31.00 bar.

Standards and conformity

The component identification TÜV.SV...-882.10.D/G.0.71 CE0036 31 bar proves the type approval and states the notified body CE0036 together with the set pressure. Valves of this series are delivered with fixed settings between 0.2 and 50 bar, here at 31.00 bar. An NPT thread and a setting certificate are available as options.
