ULTRA 10-ES. MWP 16 Bar G½", ½" NPT

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
