Technical Specifications for Plug Valve

Plug Valve Manufacturer

Shree Ganesh Engineering Works, under the brand name MESCO, is a reputed manufacturer and exporter of Flanged Plug Valves. Our valves are designed for on-off and throttling service, ensuring tight shut-off, smooth operation, and long service life even under tough industrial conditions.

Plug Valve A quarter-turn rotary valve used for quick and efficient control of flow in a wide range of industrial applications. It is provided with a cylindrical or tapered plug with a through-port which is rotated to start or stop the flow of liquids, gases and slurries. The Plug Valve is a simple design that offers a tight shut-off and low operating torque. This valve provides reliable service with little maintenance. Plug valves are made of high quality cast iron, cast steel, stainless steel and alloy steel, and are widely used in oil and gas, chemical processing, water treatment, petrochemical, power generation and industrial pipeline systems.
