Safety non-return valve R53-ES

for gasfor oxygenstainless steel

Non-return valve stainless steel for the prevention of unintended gas mixtures, for flow rates up to 130 m³/h (air), up to 25 bar, G 1/8 - 3/8 safety element: non-return valve [NV] every non-return valve 100% tested ultra-low opening pressures (approx. 30 mbar), ultra-low pressure drop compact and light: 25 X 71-78 mm, 39 g Information WITT non-return valves for reliable protection against dangerous reverse gas flow. Every non-return valve 100% tested. The best non-return valves in the world. 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 (approx. 30 mbar) no leaks – using a spring-loaded valve assembly with elastomer sealing diverse applications – useful for many technical gases reduce installation costs – the spring-loaded valve is not affected by gravity and may be installed in any orientation Operation / Usage: non-return valves are used to protect equipment and pipelines against dangerous reverse gas flow. Use is possible for applications according to EN 746-2 WITT non-return valves may be mounted in any position / orientation 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 ISO 9001 Cleaned for Oxygen Service according to EIGA IGC Doc 13/12/E: Oxygen Pipeline and Piping Systems
