The gate valve is the most widely used ON/OFF valve for large diameter, full port applications. When the valve is fully open, it allows straight-through passage through and opening that is essentially the same size as the inside diameter of the connecting pipe. The valve operates when the hand wheel and stem screw (or electric actuator) move a cylindrical plug, the gate, up and down at right angles to the fluid flow. Traditionally, gate valves have been used only for ON/OFF service, but because the unique Asahi/America sliding plug design provides a larger seating area than conventional gate valves, it can be used for throttling. This significantly larger seating area, which runs 360 degrees around the cylindrical plug, has also virtually eliminated the valve chatter normally associated with gate valves. Asahi/America gate valves feature a solid polypropylene plug with a non-rising stem design. Ideal Applications Include: ON/OFF, chemical processing, aquariums, mining, water treatment, landfills.
