Extractor Pneumatic Check Valve

1. Multiple end connections, VCR/compression fitting/female/male connection methods are optional.
2. All-welded design, no internal threads.
3. FKM sealing ring ensures the possibility of sealed switching.
4. Forward flow can be generated when the upstream pressure is less than 0.14 bar (2 PSIG).
5. It can be closed when the back pressure is less than 0.4 bar (2 PSIG).
6. Standard average internal surface roughness is Ra20 uin. (0.5um), electropolishing to a roughness of Ra10 uin. (0.25um) is optional.

Note

The extractor pneumatic check valve is designed only for controlling the flow direction and should never be used as a safety release device.
When the extractor pneumatic check valve has not been opened for a period of time, its initial opening pressure may be higher than the set opening pressure.
