These valves are designed for least possible obstruction to free flow by providing curvature turns in the body. Thereby minimising stresses & turbulences also. Discs are plug type and held together with steam by disc nut & allows the perfect seating arrangement on the seat. Carbon Steel & Cast alloy valves have renewable seats while stainless and other higher grade materials have integral seats. All the valves have back seat arrangement as an additional sealing under full working pressure which facilitated replacement of packing with the valve under fully open condition.
OPTIONAL FEATURES
1. 'Y' type body construction.
2. PTFE Disc.
3. Renewable Seat rings.
4. Screwed Bonnet.
