Frequently Ask Questions

What Is a Metal Seated Gate Valve?

A Metal Seated Gate Valve is a gate valve that uses a metal gate/wedge and metal seating surfaces to isolate the flow. Unlike resilient-seated valves, its sealing surfaces are designed to withstand higher temperatures and demanding mechanical conditions.

Is It Suitable for High-Temperature Service?

Yes. Metal-seated gate valves are particularly suitable where temperature exceeds the practical limits of many elastomeric or polymer seats.

What Is the Difference Between Metal Seated Gate Valve and Forged Steel Gate Valve?

A Forged Steel Gate Valve describes the manufacturing/body construction, whereas Metal Seated Gate Valve describes the seating arrangement. Therefore, a valve can technically be both: Forged Steel + Metal Seated Gate Valve.

What Is the Main Advantage of a Metal Seat?

The major advantage is high temperature and wear resistance. Metal seating is commonly selected for steam, high-temperature fluids and demanding industrial services.

Who Is a Metal Seated Gate Valve Manufacturer in India?

Alis Valves is an industrial valve manufacturer and supplier in India offering gate valves and valve automation solutions for demanding industrial applications. Based in Ahmedabad, Gujarat, Alis Valves serves industries including oil & gas, refineries, petrochemical, power generation, chemical and process industries, with valves available in different materials, sizes and pressure ratings.

What Is the Difference Between Rising and Non-Rising Stem?

Rising Stem: The stem moves upward as the valve opens, providing visible position indication. Non-Rising Stem: The stem rotates without significant external upward movement, making it useful where installation space is limited.
