Metal Seat Control Valve

Metal Seat Control Valve

A Metal Seat Control Valve is a type of valve designed for controlling fluid flow by adjusting the size of the flow passage based on signals from a controller. It is equipped with metal seats, which are chosen based on the specific requirements of the application. For instance, copper alloys are used for low-pressure valves, while nickel-based alloys are preferred for corrosive media.

These valves are capable of withstanding harsh conditions such as acids, heat, abrasives, hydraulic shock, erosion, corrosion, and high pressure, making them suitable for demanding environments. Although metal seat control valves generally cost more than soft-seated valves, they offer enhanced durability and performance under extreme conditions. However, they may also have higher leakage rates compared to their soft-seated counterparts. Evaluating the total cost of ownership and the specific service conditions can help determine the best valve type for a given application.
