Description
Stainless steel threaded gate valve is the kind of valves that fully opened and fully closed for fluid control. The opening and closing part of the gate valve is its gate plate, the direction of the motion of the gate plate is perpendicular to the direction of the fluid, when valve is opening, the fluid can go through the valve immediately without any block, when valve is closing, the fluid can be cut off immediately and fully.
Compared with other metal material, Stainless steel have overwhelming advantages in pressure resistance, high temperature resistance, low temperature resistance, corrosion resistance, valve life and so on. For its excellent valve function, the stainless steel threaded gate valves are widely used in chemical food petroleum energy pharmaceutical construction industries.
Features:
1.The gate plate motion direction is vertical to the medium flow direction, small torque for open and close, which makes the open and close of the valve is easy and flexible.
2.Medium flow direction is not restricted, no disturb for flow, no pressure reduce, medium can flow to any direction through the gate valve, which can applied to the pipeline medium flow may be changed.
3.Due to its long on-off operation time, it will not happen the Water hammer phenomenon.
4.Compared with brass, the stainless steel can handle greater range of temperatures and pressures, better functions for corrosion resistance, valve life and so on.
5.Superior performance, not only high sealingability, safe and reliable, but also excellent performance, beautiful shape.
