Lubricated Taper Plug Valve Screwed
MVS Lubricated Plug Valve screwed ends is manufactured in sizes from ½” to 3”, is used on a wide variety of liquid, gaseous and slurry services. MVS Lubricated Plug Valve Screwed has its integral operating shank at the large end of the taper plug. This reduces friction between the plug and the packing and also acts as a separate and very effective seal against leakage of the line fluid into the packing space.

LUBRICANT CUM SEALANT (LUB STICKS) : Lub-Seal available with us for different kind of application like L.P.G., Ammonia, Hi-Temperature, On request, plug sealant from a wide range offered, can be supplied to suit the nature of service. It is recommended that you consult us before selecting the plug sealant for a new service.
FEATURES / BENEFITS :
Longer service life through tapered seat surfaces of the plug and body that prevents exposure to line fluid when valve is in the open position
Increased reliability due to the straight flow path design that minimizes pressure loss by allowing very little resistance to flow
