Plug Valves

Lo-Torq Plug Valves:

The MSI LT Plug Valve is a lubricated, tapered seal, quarter-turn plug valve for rapid full open or close operation. The valve cavity is tapered to ensure uniform seating of the sealing inserts, providing a reliable seal at the full range of pressures. The MSI LT Plug Valve and replacement parts are engineered to provide low operating torque and resistance to the toughest abrasive and corrosive conditions.

Top-Entry Plug Valves:

The MSI TE Plug Valve is a lubricated, straight pocket, quarter-turn plug valve for rapid full open or close operation.
