Function
The Grooved Gate Valve functions as an isolation valve, used primarily to start or stop flow in grooved piping systems. When the handwheel or actuator turns the stem, the encapsulated wedge moves vertically to open or close the passage, creating a tight seal when closed. Thanks to its grooved ends, the valve is quickly installed between grooved couplings without flanges or welding, reducing labor and downtime.
our valve supports bi-directional flow, and its rubber-seated wedge ensures leak-tight shutoff under fluctuating pressure conditions, making it ideal for systems requiring high reliability, such as sprinkler mains or mechanical equipment loops.
Vcore grooved gate valves are typically constructed from ductile iron or cast iron with a corrosion-resistant fusion bonded epoxy coating. The valve body includes an encapsulated resilient wedge, ensuring tight, bubble-free shutoff under both low and high pressures. Operated manually via handwheel or actuator, this non-rising stem valve is suitable for both vertical and horizontal installations.
