Double Disc Valve

Double disc valves (parallel seat valves) deliver unmatched sealing for high-pressure steam, gas, and thermal oil systems. Featuring two parallel discs forced against seats by a central wedge, these ASME B16.34 valves achieve ANSI Class VI shutoff at 2,500+ PSI and 1,000°F (538°C) – eliminating seat galling and thermal binding in power plants, refineries, and district heating networks.
