Pneumatic Valve Series Z643H Pneumatic Flat Gate Valve
Product Overview:
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.
