Feb 01, 2019 · The plug disk gate valve differs from other gate valves in that it can be used in a throttling service (Figure 4.53). This configuration offers minimum resistance to flow when fully open, a feature common to most gate valves. They are used where minimal pressure drop (unrestricted flow) is required.

They are parallel seat valves meeting or exceeding all requirements AWWA C500. Learn More; Solid Wedge Gate Valve. Kennedy Solid Wedge Gate Valves are available in both NRS and OS&Y bonnet Gate Valves - EnggCyclopediaGate Valves. Gate valves get their name because of a flat or tapered disc that can slide vertically in and out of the path of the flow, at right angles to the direction of flow, thus blocking the flow. The vertical disc which is normally referred to as the 'gate' slides along a track which is also referred to as seat of the gate.
The disc of a gate valve is entered into a process system and different configurations are specified depending on process requirements. Gate valves can be divided into groups based on the type of disc:double-disc, knife, wedge, and full bore conduit. Double Disc Gate Valve Introduction to Gate Valve - The Process PipingApr 21, 2020 · The gate valve, as illustrated in on the right, generally consists of a gate-like disc, actuated by a screwed stem and hand-wheel which moves up and down at right angles to the flow. In the closed position, the disc seats against two faces to shut off flow. KENNEDY VALVE AWWA Dbl. Disc Parallel Seat IBBM Dec 15, 2009 · Kennedy Valve/Double-Disc GV 9-1 KENNEDY VALVE AWWA Dbl.

- How It WorksFeaturesBenefitsPeople also askHow does a double disk parallel gate valve work?How does a double disk parallel gate valve work?A double-disk parallel gate valve has two parallel disks that are forced, on closure, against parallel seats by a spreader. They are used for liquids and gases at normal temperatures. On the other hand, the seating force in a single-disk parallel gate valve is provided by the fluid pressure acting on either a floating disk or a floating seat.Gate Valve - an overview ScienceDirect Topics
