Features
- The concentric disc offers bi-directional service and allows high Cv values with its symmetric shape
- Primary seal is formed by the disc hub and stem top, the seat contact exceeds the pressure rating of the valve
- Secondary stem seal is suitable for high pressure and is self-adjusting
- Disc hub edge are rounded and hand polished to provide full concentric sealing without seat obstruction to flow, combined with maximum seat life
- Replacement seat isolates the stem and body parts from the stream and also serves as the flange gasket
- Moulded-in O-ring provides positive flange sealing and eliminates the need for gasket
- Double flanged body design specified according to JIS F7480
- Heavy duty top bushing absorbs side thrust and torque loads
- Stainless steel disc screws allow quick and easy disassembly
- Factory testing of every valve at full rating ensures 100% tight shut-off
