Product features

Electric flange gate valve (Z941H) is composed of stainless steel flange gate valve and electric actuator, which is stable and reliable when used in the pipeline, so flange gate valve is often used in high-pressure pipeline. The electric flange gate valve is a kind of remote automatic control gate valve. The valve stem drives the valve stem to move up and down through the power supply to control the opening and closing of the gate valve. It is applicable to the system pipeline under various working conditions with nominal pressure of PN1.6~16.0MPa and working temperature of ≤ - 29 ℃~550 ℃. It is mainly used for cutting off or connecting. It is generally not recommended to regulate the medium flow.
 
Advantages of electric flange gate valve:
 
1. The fluid resistance is small, the medium channel inside the valve body is straight through, and the medium does not change its flow direction when flowing through the gate valve.
2. The erosion and erosion of sealing surface medium is small.
3. Simple shape, good manufacturing process and wide application range.
4. The opening and closing is more successful, and the movement direction of the ram is perpendicular to the flow direction of the medium.
5. The flow direction of the medium is generally unrestricted, and the medium can flow through both sides of the gate valve in any direction.
