Features & benefits

• The concentric disc offers bi-directional service and allows with its symmetric shape high Cv valves.
• 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 pressure 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.
• Molded-in 'O'-ring provides positive flange sealing and eliminates the need for gasket.
• Double falnged body design specified acc. 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 110% tight shut-off.
• Type approved by various major shipping class.
