The parallel single gate valve is a kind of single gate valve. It is named because the two sealing surfaces of the gate are parallel and the sealing surface of the valve seat is perpendicular to the center line of the pipeline.

It can not rely on its body to achieve a forced seal but must be fixed or floating soft seat. It is suitable for medium and large caliber, and the medium is oil and natural gas.
 
Performance advantages:
1. Low fluid resistance.
2. The external force required for opening and closing is small.
3. The flow direction of medium is not limited.
4. When the valve is fully opened, the erosion of the sealing surface by the working medium is smaller than that of the stop valve.
5. The shape is simple and the casting process is good.
