Dear All,
A metal seated, lubricated, 4" plug valve is presently used for the following conditions:
Fuel Gas, Design Temp of 70 Deg C, Pressure of 25 bar, gas associated with dust and the valve operation could be about 10 times a day to take out the dust from a cyclone separator. But it is observed valve is passing at about five operations at the most.
Which could be the best specification for this service? with regards
DKMRAO
Mech Engineer
