Double Disc Gate Valve Supplier in USA — SVR Global

SVR Global is a trusted Double Disc Gate Valve Manufacturer and Supplier in USA and Canada, providing robust and reliable valves designed for on–off flow applications in demanding industries. Our double disc gate valves are engineered with two discs and two parallel seats, which expand against the valve body to create a tight seal. This design ensures zero leakage, long service life, and smooth operation even under high-pressure and abrasive conditions.

Function & Working

A double disc gate valve operates by lifting the gate discs through the valve stem, allowing full and unobstructed fluid flow. During closing, a spring or mechanical wedge forces the two discs apart, pressing them firmly against the seats to achieve a tight seal on both sides. This self-seating action minimizes wear, reduces leakage risk, and ensures reliable shutoff. These valves are primarily used for isolation purposes and are not suitable for throttling applications.
