  • Cast Iron Globe Valve

    Cast Iron Globe Valve

    Cast Iron globe valve is a forced-sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface to not leak. When the medium enters the valve from below the disc, the resistance that the operating force needs to overcome is the friction force of the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so Cast Iron The diameter of the valve stem of the globe valve should be large, otherwise the valve stem will bend up failure.

  • Wafer Type Butterfly Control Valve

    Wafer Type Butterfly Control Valve

    Wafer type butterfly control valve are used for isolating and regulating flow. The closing mechanism is a disc that allows for quick shut off, much like a ball valve. Wafer type butterfly control valve are light in weight so they require less support. Unlike the ball valve, the disc is always present within the flow, therefore a pressure drop is always induced during flow, regardless of valve position. The disc is typically rotated a quarter turn when the valve is fully opened, but the valve may also be opened incrementally in order to throttle flow.
