WITT non-return valves (check valves) for reliable protection against dangerous reverse gas flow. Every non-return valve (check valve) 100% tested.
Benefits:
a spring-loaded non-return valve (check 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
no leaks – using 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 (check valves) are used to protect equipment and pipelines against dangerous reverse gas flow. Use is possible for applications according to EN 746-2
ideal for use with corrosive gases in the chemical industry, process technology or in laboritories
WITT non-return valves (check valves) may be mounted in any position / orientation the maximum ambient / working temperature is 70 °C / 158 °F
