Z643WF pneumatic flat gate valveDetailed product description：

Z643WF pneumatic flat gate valve has reliable performance, easy operation switching and maintenance. It is suitable for natural gas, petroleum, chemical, environmental protection, urban pipelines, gas pipelines and other transportation pipelines, venting systems and steam storage devices, and is used as an opening and closing equipment. Long distance pipelines suitable for natural gas extraction and purification.

Structural features:
The sealing structure of the valve seat should be elastic with pre tightening force, and the upstream and downstream sealing seats should be sealed simultaneously. The valve seat and seal are always sealed face-to-face.
2. The valve seat has a self-cleaning function and is not directly flushed by the airflow during the valve opening or closing process. The valve seat should be made of lubricated and wear-resistant materials.
3. The malfunction of the valve actuator will not affect other parts of the valve, and maintenance and replacement work can be carried out without disassembling the valve.
