Stainless Steel Knife Gate Valve
Gate valve, is a valve that opens by lifting a round or rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is the sealing surfaces between the gate and seats are planar, so gate valves are often used when a straight-line flow of fluid and minimum restriction is asked.
Gate valves are characterized as having either a rising or a non-rising stem. Rising stems provide a visual indication of valve position because the stem is attached to the gate such that the gate and stem rise and lower together as the valve is operated.
Non-rising stem valves may have a pointer threaded onto the upper end of the stem to indicate valve position. Non-rising stems are used underground or where vertical space is limited.
Knife gate valve
The knife gate valve is a uni-directional wafer valve for general industrial application. The structure of the uni-directional knife gate valves is a wafer style cast monoblock body, with raised face and reinforced ribs for larger nominal diameters for extra body strength. The plate radius of the knife gate valves slide gate has a bevelled cutting edge. As a result, solids can be cut through, achieving a tight seal in the closed position. On request, the thickness of the knife gate valves plate can be increased for higher operating pressures and/or higher quality material can be used.
1.The liftable disc sealing surface can shave sticky things on the sealing surface automatically.
2. The stainless disc can prevent the seal leakage caused by erosion
.
3. the knife gate valve features short structure which saves raw materials for manufacturing and installation space as well as sustains the pipe efficiently.
4.Drive actuators offered for the knife gate valve include hand-wheel with rising or non-rising stem, or alternatively double-or single-acting pneumatic cylinders (spring return), Bevel Gear, chain gear and electric actuators.
5. the medium of knife gate valve is water, kerosene and other liquids whose viscosity is weaker than water.
