Witt Non Return Valves (NRV) for gases
Order in the next
for guaranteed delivery tomorrow!
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
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
