Gas non-return valve NV2000

for oxygenbrassstainless steel

safety element: non-return valve [NV] every non-return valve 100% tested ultra-low opening pressures (approx. 5 mbar), ultra-low pressure drop dirt filter (100 μm) in the gas inlet to be mounted in vertical position / orientation in accordance with EN 746-2 320-340 X 393-450 mm, 50 kg WITT non-return valves for reliable protection against dangerous reverse gas flow. Every non-return valve 100% tested. Benefits: a spring-loaded non-return valve prevents a reverse flow of gases which could lead to unwanted gas mixtures low pressure drops – using complex valve assembly with low opening pressures, NV2000 approx. 5 mbar no leaks – using of a spring-loaded valve assembly with elastomer sealing stainless steel filter (100 μm) in the gas inlet protects the non-return valve against dirt contamination, extending the service life diverse applications – useful for many technical gases Operation / Usage: non-return valves are used to protect equipment and pipelines against dangerous reverse gas flow. Use is possible for applications in accordance with EN 746-2 the NV2000 may be mounted vertical in bottom-up flow direction Maintenance: annual testing of the non-return valve and body leak tightness is recommended WITT is happy to supply special test equipment non-return valves are only to be serviced by the manufacturer Approvals Company certified to ISO 9001 and PED 2014/68/EU Module H CE-marked in accordance with PED 2014/68/EU Designed for Oxygen Service in accordance with EIGA 13/20 and CGA G-4.4: Oxygen Pipeline and Piping Systems
