Electric gate valve is controlled by electric actuator to realize valve opening and closing. The upper part is electric actuator while the lower part is valve body. Its action speed is adjustable, structure is simple and maintenance is easy. Due to buffering nature of gas, it doesn’t easily jam or damage. It boasts sensitive response, safety and reliability.
Advantages：
1. Small flow resistance. Internal medium channel is straight through, so medium flows straightly and realizes small flow resistance.
2. Easy opening and closing. Compared with stop valve, during opening or closing, movement direction of gate is perpendicular to flow direction of medium.
3. Large height, long opening and closing time. The gate owns large opening and closing travel; fall is realized by screw rod. 
4. Water hammer seldom occurs due to long closing time.
5. Medium flows to either direction at both sides. It is easy to install. Both channels are right.
6. Structure length (distance between two connecting end faces of shell) is small.
7. Simple shape, short structure length, good manufacturing technology and wide range of application.
8. Compact structure, good valve rigidity, smooth channel and small fluid resistance. Sealing face made of stainless steel and hard alloy owns long service life. PTFT padding boasts reliable sealing and convenient and flexible operation.
