These valves are designed to provide minimum turbulance &
resistance to flow when
in fully open position. Sufficiently long guide ribs in the
body along with accurately
machined wedge & guide slots ensure accuate control &
allignment of wedge while
operating. Wedges are generally solid type & are
accurately machined, precisely
alligned & prefectly 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 whcih
facilitated replacement of packing with
valves under fully open condition.
