Information
WITT non-return valves for reliable protection against dangerous reverse gas flow. Every non-return valve 100% tested.
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
- 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 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 laboratories
- WITT non-return valves may be mounted in any position / orientation the maximum ambient / working temperature is 70 °C / 158 °F
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. The dirt filter may be replaced by competent staff
