✔︎ Robust design according to AWWA C504, API 609, EN 593, IS 13095 standard.

✔︎ The offset disc produces a cam-like action, pulling the disc from the seal. This action reduces seal wear and eliminates seal deformation when the disc is in the open position. The disc does not contact the seat when the valve is in the open condition, therefore seat service life is extended and torques are reduced.

✔︎ One piece cast double flanged body provides dead-end service with downstream piping to be removed while pressure is maintained on the upstream. Available in various flange standards (ASME /AWWA /MSS-SP /DIN /JIS /BS /IS)

✔︎ Heavy-duty ‘T’ cross-sectional seat mechanically retained by seat retainer ring into the body allows seat adjustment and repair without removing the valve or dewatering the pipeline.

✔︎ Easily adjusted and replaced in the field. The 360◦ resilient seat is uninterrupted for positive sealing.

✔︎ High strength stub shaft has minimum 1 ½ diameter penetration into the disc-hubs with closed fit.

✔︎ Self-lubricating, sleeve type bearing in both the trunnions of the body. Bearings support the shaft and provide minimum friction during shaft rotation.

✔︎ Disc is designed for high strength with concave surface for greater flow through valve opening and less pressure drop.

✔︎ Body internal diameters and disc can be supplied with 3mm rubber lining for sea water application and various corrosive applications.

✔︎ An inherently rigid design, the upper and lower shafts are secured to the disc by pins, totally enclosed within the disc.

✔︎ Axial bottom shaft thrust bearing carrying the disc weight when valve is installed with shaft in vertical position and ensuring accurate centering of the disc assembly.

✔︎ Self adjusted graphite rings provide 100% leakage prevention from stem. Packing is easily replaced without removal of the valve from the line.
