STRUCTURAL FEATURES

Construction of Lubricated Plug Valves

Primary Seal by Metal-to-Metal Seatings:

The primary sealing is achieved by the seating surfaces metal body and seat surfaces.

Secondary Seal by Sealant Action:

As a secondary seal, the valve is provided with a lubrication system which allows feeding a special sealant into the valve while the valve is in operation. Besides sealing,the lubricant is to protect the internals of the valve against corrosion and wear as well as reducing the valve torque. Sealant injection system ensures that all seal faces are supplied with thin coat of lubricant and by so doing becomes an efficient secondary seal.
