Resilient Seated Gate Valve
The Test Torque is the amount of force required to open or close the valve. For a Resilient Seated Gate Valve, the torque is primarily influenced by the nominal diameter and pressure rating. Below is a typical torque chart, which should be cross-referenced with the manufacturer’s specific data for more accurate results.
Resilient Seated Gate Valve
The Resilient Seated Gate Valve is a soft-sealing isolation valve designed for reliable shut-off service in water supply, wastewater treatment, fire protection, irrigation, and industrial utility systems. The valve features a ductile iron or cast steel body and an elastomer-coated wedge, providing bubble-tight sealing performance with zero visible leakage.
Compared with traditional metal-seated gate valves, resilient seated gate valves offer superior sealing, corrosion resistance, lower operating torque, and maintenance-free operation. The full-bore design ensures minimal pressure loss and unrestricted flow, making it an ideal solution for municipal and industrial pipeline networks.
As a professional valve manufacturer, we offer comprehensive OEM and ODM services for global infrastructure and industrial projects.
