    Valve Specifications

    Gate Valve Application
    Gate valve are primary used for stop valves fully opened or fully closed. They are not normaly considered for throttling purpose, but more for slurries, viscous fluids, etc. Gate valves are characterized by a traveling wedge, which is moved with the operation of the stem nut. the wedge travels perpendicular to the direction of the flow.
    Gate valves usually have a minimum pressure drop when fully open, provide tight shut-of when fully closed and remain relatively free of contamination buildup.
