Check valve
0,004 - 40 bar, 0,001 - 3.000 qm/h WITT-Gasetechnik

WITT gas Non-return Valves protect equipment, pipelines and outlet points. Varying from 0.004 bar - 40 bar (0.06 - 580 psi) and flows between 0.010 m³/h - 3.000 m³/h (0.35 - 105925 SCFH) with any wanted connection. Nearly every application will find a solution when gas return has to be prevented.

Some non-return valves are flashback safe in accordance with EN 730 when natural gas and air are mixed, which can be mounted in nay position and do not require gravity.

• Avoid the formation of explosive mixtures in the gas supply
• Varying from 0.004 bar - 40 bar and flows between 0.010 m3/hr - 3.000 m³/hr with any wanted connection
• For all technical gases – wide range of applications
• Low pressure drops - using complex valve assembly with low opening pressures
• No leaks - using of a spring loaded valve assembly with elastomer sealing
• Installation independent of the orientation
• All connections available
• Available in brass or stainless ste
