Ultra-performance protection against gas return: compact, quiet, ideal for low pressure applications. Opening pressure approx. 4 mbar, working pressure up to 16 bar, G / NPT 1′, 1/2′, 3/4′ safety element: non-return valve [NV] every non-return valve 100% tested DIN EN ISO 5175-2 ultra-low opening pressures (approx. 4 mbar), ultra-low pressure drop compact and light: 52 X 67,5 mm, 510 g, G / NPT 1′, 1/2′, 3/4′ minimal noise emission dirt filter (100 μm) on gas inlet ideal for applications where low pressures are used e.g. thermal processing, biogas etc. 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. 4 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 the same size as model NV200 for easy replacement
