Safety valve, preset and lead-sealed, G 1/2", DN 10, 3.50 bar, stainless steel 1.4571

The safety valve limits the pressure in compressed air systems and opens automatically as soon as 3.50 bar is reached. In that case up to 154.1 m³/h are discharged freely until the system pressure falls below the set value again. The valve body is made of stainless steel 1.4571 and is screwed in through the G 1/2" thread in nominal size DN 10.

Benefits

• Usable from -25 to +180 °C thanks to the FKM seal.
• Body made of stainless steel 1.4571, approved for compressed air and other non-toxic, non-flammable gases.
• The set value of 3.50 bar stays traceable and unchanged thanks to the lead seal.
• Discharge capacity of 154.1 m³/h, referred to the set pressure of 3.50 bar.
• Screwed in through G 1/2" in DN 10 and tightened at the 27 mm wrench flat.

Technical data

Applications

• Installation in systems with operating temperatures between -25 and +180 °C.
• Test benches and machines where the set pressure of 3.50 bar has to be sealed and documented.
• Protection of compressed air receivers with a permissible working pressure of 3.50 bar.

Standards and conformity

The component identification TÜV.SV...-882.10.D/G.0.61 CE0036 3,5 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 3.50 bar. An NPT thread and a setting certificate are available as options.
