need to retightening
gland nut.
Valves bottom spindle
made from Naval Brass
for extra toughness and
wear resistance. Valve
top spindle machined
from SS-304 giving
resistance against over
torque beyond 50 Nm.
Soft seating in bottom
spindle ensures no
increase in torque
during the service life
of the valve.
Bottom spindle, thrust
washer and 'O' rings are
lubricated to minimize
seizing and galling
under high-pressure
operation.
KVO - 10 tested for
impact for use in
cylinders, having weight
of the package mass not
exceeding 83.33 kgs,
without valve protection
cap.
Valves can be provided
with PRD as per
