Design
Features :
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.
