Valve overview:
A pneumatic film regulating valve is a sealed regulating valve, which has two functions cutting and regulating. The valve core adopts an upward guide structure, which has the characteristics of small size, simple structure, wide adjustable range, and high flow characteristic accuracy.
Executive standard:
Design standard: GB/T4213-2008
Sealing performance: GB/T4213-2008
Installation and maintenance matters
When installing the valve, it should be noted that the flow direction of the wide door mark should be consistent with the flow direction of the medium
The valve should be installed vertically, make sure the valve is open when welding
Make sure the pipes are blown clean before installation
After the pipeline installation is completed, open all the doors and purge repeatedly to ensure that the pipeline is clean and free of residual impurities
It is recommended to use dry nitrogen or compressed air for pressure tests. It is strictly forbidden to use a low-temperature medium after a hydrostatic test
When ordering, please note whether the valve action is air-opening or air-closing.
