Double Disk Gate Valves

The ability to move large water and wastewater flows must be matched by the ability to stop flow. Accordingly, Patterson’s Ludlow-Rensselaer double disc gate valves complement our heavy-duty pumps. The proven, double-wedging, locking gate design meets or exceeds A.W.W.A. C500 in high-pressure water and wastewater applications. They are also widely used by industry in chemical process, iron and steel and pipeline service.

Types include round- or square-bottom valves (for throttling service on discharge side) and slimline valves (for isolation on the suction side) featuring short flange-to-flange dimensions and clean-out ports as standard. Diameters range from 14 in. to 84 in., with pressure ratings from 50 psi to 375 psi.
