These valves are designed for least possible
obstruction to free flow by providing
curvature turns in the body. Thereby minimizing
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.
