Обратный клапан ULTRA 12
На основе ULTRA 10 - Ваш индивидуальный дизайн: несколько комбинаций материалов корпуса и уплотнителя, с фильтром или без него
- свободная комбинация материала для корпуса (латунь, нержавеющая сталь, алюминий) и уплотнителя (NBR/CR, FPM/FKM, EPDM/FFKM), с фильтром или без него
- для особых требований, например, для агрессивных сред, ацетилена, легкой конструкции, температур выше 70 °C
на основе ULTRA 10 включительно:
- предохранительный элемент: обратный клапан [NV]
- каждый клапан 100% проверен
- DIN EN ISO 5175-2
- минимальная потеря давления – благодаря специальной системе клапанов с низким давлением открытия (ca. 4 милибар)
- 35 X 60 мм, 221 гр., G ½"
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 drop – using complex valve assembly with low opening pressures (approx. 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, stainless steel or aluminium
- 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
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
Approvals
Company certified according to ISO 9001
Cleaned for Oxygen Service according to EIGA IGC Doc 13/12/E: Oxygen Pipeline and Piping Systems
