Safety valve, preset and lead-sealed, G 3/4", DN 10, 8.50 bar, stainless steel 1.4401

The safety valve limits the pressure in compressed air systems and opens automatically as soon as 8.50 bar is reached. In that case up to 383.85 m³/h are discharged freely until the system pressure falls below the set value again. The valve body is made of stainless steel 1.4401 and is screwed in through the G 3/4" thread in nominal size DN 10.

Benefits

• Factory set to 8.50 bar and lead-sealed, so the set pressure is protected against unauthorised adjustment.
• At 8.50 bar the valve releases 383.85 m³/h, a figure that applies to free discharge into the surrounding air.
• The G 3/4" thread and nominal size DN 10 suit common compressed air manifolds, spanner size 32 mm.
• Overall height H of 75 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.

Applications

• Protection of gas lines carrying non-toxic, non-flammable gases up to 8.50 bar.
• Installation in systems with operating temperatures between -25 and +180 °C.
• Test benches and machines where the set pressure of 8.50 bar has to be sealed and documented.

Standards and conformity

The component identification TÜV.SV...-882.10.D/G.0.71 CE0036 8,5 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 8.50 bar. An NPT thread and a setting certificate are available as options.
