Product Description

Product Description

Design principle:Hunan Wofly's DCOS11 series semi-automatic conversion system is suitable for continuous gas supply, and the exhaust at one end is automatically switched to the other end. The priority air source can be selected by turning the switch handle. Each diaphragm valve inlet can be connected with a gas cylinder. If a gas manifold is used at the inlet end, two or more gas cylinders may be connected to each inlet end.



Clean process
The product is cleaned and packaged in accordance with AST G93 Class C cleaning requirements.
BA-grade: Product Surface roughness reached Ra 0.25 um and can be applied to gases below 6N purity.
Cleaning for oxygen (O2): It can provide cleaning and packaging specifications for products used in an oxygen environment, which meets the cleaning requirements of ASTMG93 C. When ordering, please add -O2 after the ordering number.
