Gas non-return valve ULTRA 12

DINsafetybrass

Based on ULTRA 10 – your customised design: multiple combinations of housing and seal materials, with or without filter free combination of material for housing (brass, stainless steel, aluminum) and seal (NBR/CR, FPM/FKM, EPDM/FFKM), with or without filter for special requirements e.g. corrosive environments, acetylene, lightweight construction, temperatures above 70 °C/ 158 °F based on ULTRA 10 including: 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: 35 X 60 mm, 221 g, G ½" minimal noise emission 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. ULTRA 12 is based on ULTRA 10 and is customised according to the requirements of the customer - ideal for special requirements. A modular system which allows flexible material combinations for housing and sealings. Combination possibilities housing available in brass, stainless steel or aluminium sealings of NBR, CR, FKM, EPDM, FFKM for example with or without dirt filter in gas inlet Benefits precisely tailored design for special requirements. For example corrosive environments, acetylene, ultra-lightweight construction, temperatures above 70 °C / 158 °F 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 (approx. 4 mbar)
