Gate Valve
Gate Valves are linear motion isolation valves designed for full open or full close service, providing minimum pressure drop when fully open. They are widely used in water, steam, oil, gas, chemical, power, and process industries where reliable isolation and long service life are required.
MNC Gate Valves are manufactured in Class 150 / 300 / 600 with Flanged and Butt Welded end connections, suitable for a wide range of operating conditions.
Description
