Информация

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 drops – 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 with DIN EN ISO 5175-2
available in brass or stainless steel (ES)
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
in ambient temperatures above -20 °C / 68 °F and below +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
