Design To BS 1868
Cast with uniform wall thickness smooth flowing contours and generous fillet radii to prevent stress concentrations. Designed for structural stability, mechanical strength and safe weld ability. Precision machined.
These valves are designed for least possible obstruction to free flow by providingcurvature turns in the body. Thereby minimizing stresses & turbulences also. Discsare 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 seatswhile stainless and other higher grade materials have integral seats. All the valveshave back seat arrangement as an additional sealing under full working pressurewhich 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.

These valves are designed to provide minimum turbulence & resistance to flow when in fully open position. Sufficiently long guide ribs in the body along with accurately machined wedge & guide slots ensure accurate control & alignment of wedge while operating. Wedges are generally solid type & are accurately machined, precisely aligned & perfectly lapped with renewable seats in Carbon Steel & integral seats in Stainless Steel. All the valves have back seat arrangement as an additional sealing under full working pressure which facilitated replacement of packing with valves under fully open condition.
Optional Features
* Flexible Wedge.* Split Wedge* Non rising stem* Renewable seat ring & back seat.
