Electric Flat Gate Valve
Introduction:
The electric flat gate valve is suitable for natural gas, petroleum, chemical, environmental protection, urban pipelines, gas pipelines and other transmission pipelines, venting systems and gas storage devices, as opening and closing equipment. It is suitable for long-distance pipelines for natural gas extraction and purification.
Features:
1. The sealing structure of the valve seat should be elastic and pre-tightened, and the upstream and downstream sealing seats should be sealed at the same time. There is always a face-to-face seal between the seat and the seal.
2. The valve seat has a self-cleaning function and is not directly washed by the air flow during the opening or closing of the valve. Seats shall be made of lubricated, nonabrasive material.
3. The failure of the valve actuator will not affect other parts of the valve, and maintenance and replacement can be carried out without dismantling the valve.
