Parameter:
Stainless steel manual internal thread gate valve, also called the cut-off gate, is the most widely used kind of valve, belongs to the forced sealing type valve, its closing principle is, relying on the pressure of valve bar, so that the sealing surface of the valve flap and the sealing surface of the valve seat closely fit together, stopping the flow of media. It is divided into several types according to different ways. The internal thread gate valve has a simple structure, good sealing life, fluid resistance, poor adjustment performance, etc.

1.Small flow resistance .the way inside valve is direct through,the media can easily through the inside way, flow resistance are small.
2.Operate portably and flexibly,compare with globe valve ,the way of Disc move is Vertical with media whether open or close.
3.It is take a long time to open or close because long stem.
4.Water hammer phenomenon will nor happen because it cost long time to open and close.
5.The medium can flow in any direction on both sides, and is easy to install. Gate valves are symmetrical on both sides of the channel.
