Features:
1.The flow resistance is small. Body's internal media channel is through the medium into a linear flow, flow resistance is small.
2.Open and close more effort. Is compared with the valve, because whether it is open or closed, the gate were medium flow and is vertical to the direction.
3.Height, open and close for a long time. Gate opening and closing stroke larger drop through the screw.
4.Water hammer phenomenon is not easy to produce. The reason for this is shut down for a long time.
Application:
1.The fields of Petro-chem;
2.Pharma centical and power etc.
3.It is used by open and close on the pipes of steam,water and oil etc,under the pressure of 1.0 MPa.
