Description

safety element: non-return valve [NV] every non-return valve 100% tested DIN EN ISO 5175-2 ultra-low opening pressures (approx. 5 mbar), ultra-low pressure drop compact and light: 73,5 X 111 mm, 1.8 kg, G / NPT 1.1/2" minimal noise emission dirt filter (100 μm) on gas inlet ideal for applications where low pressures are used WITT non-return valves for reliable protection against dangerous reverse gas flow. Flow-optimised valve system causes very low pressure drop at minimal noise emission. Every non-return valve 100% tested. Benefits a spring loaded non-return valve prevents back feeding of gases which could lead to unwanted gas mixtures low pressure drop – using complex valve assembly with low opening pressures (ca. 5 mbar) stainless steel filter (100 μm) in the gas inlet protects the non-return valve against dirt contamination, extending the service life flow-optimised valve system for: - ultra low pressure drop - minimal noise emission no leaks – using of a spring loaded valve assembly with elastomer sealing in accordance to DIN EN ISO 5175-2 available in brass or stainless steel 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
