Knife Gate Valve Trough Conduit KG valve 03 is most commonly used in piping systems. Its function is to open and close the flow (on-off), but not for a large set of small flow (throttling). Excess Gate Valve, the lack of obstruction / resistance when the valve is fully opened, so the flow can be maximized. These valves valve controls the flow through the valve body is tubular, with a slab or a vertical wedge (see figure below) which can be shifted up and down when the valve handle is rotated. Valve is designed for the fully open position, or fully closed. If the valve is in a state of half-open, it will cause erosion of the valve body, and turbulence may lead to vibration in the wedge valve to produce a rattling sound.
