BALL & CHECK VALVES
Flow Control Regulators
Non-return Valves
Stainless steel flow control regulators control the speed of a pneumatic cylinder (models LE-7820 7822) or the speed of a chemical of food fluid carried (model 7822: for fluids compatible with FKM and PTFE seals) in aggressive environments or submitted to high mechanical or chemical constraints. Designed without retention zones, these models are perfectly suitable for food applications or requiring frequent washing of installations.
Legris stainless steel non-return valves allow fluids to pass in one direction whilst blocking flow in the other direction. Robust and extremely compact, they are suitable for use as a safety item in all fluids circuits.
They are ideal for use in severe conditions and in aggressive environments. Operation: A stainless steel valve blocks the fluid passage, when the pressure differential is lower than 0.25 bar.
Working Temperature: -20°C to +180°C Working Pressure: 0.5 to 40 bar
Working Temperature: -15°C to +120°C Working Pressure: 1 to 16 bar
