Lubricated Plug Valve and Pressure Balanced Lubricated Plug Valves
The lubricated plug valve flanged is the ideal shut-off device for almost any medium, even under the most severe operating conditions. Since the only moving part is the plug, the basic operation of the valve is very simple.
The only moving part is the plug. This precise adjustment and the constant lubricating film between body and stem prevents intrusion of particles inside and protect the valve for leaking and damage.
It incorporates Metal to Metal sealing, which means that no soft seal will be damaged by the flowing medium. the valve is provided with a lubrication system which allows feeding a special lubricant into the valve while the valve is in operation.
Besides sealing, the purpose of the lubricant is to protect the internals of the valve against corrosion and wear as well as reducing the valve torque.
The Lubricated Taper Plug Valve Flanged is a reliable, standard type taper plug valve designed for general isolation purposes in a variety of liquid, gaseous and slurry services. It is available in cast iron and steel to suit application.

LUBRICANT CUM SEALANT (LUB STICKS) : Lub-Seal available with us for L.P.G., Ammonia, Hi-Temperature. On request, plug sealant can be supplied to suit the nature of 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
