BS5150/DIN3352/API600D carbon steel metal seated gate valve

BS5150/DIN3352/API600D /GOST carbon steel  metal seated gate valve 

Metal-seated gate valves achieve sealing through direct metal-to-metal contact between the gate and the valve seat. Compared to soft-seated gate valves, they offer superior resistance to high temperatures, abrasion, and erosion. The opening and closing mechanism relies on the valve stem driving the gate in a vertical motion to either cut off or allow the flow of fluid.

Working Principle

When the valve is closed:

Driven by the valve stem, the gate moves downward to establish metal-to-metal contact with the valve seat, thereby achieving a sealed state.

When the valve is open:

The gate rises, fully opening the flow channel and allowing fluid to pass through with virtually no resistance (full-bore design).

This type of valve is particularly well-suited for applications in steam systems, petrochemical plants, slurry transport, power generation facilities, and the metallurgical industry. It maintains stable performance even under harsh operating conditions, offers a long service life, and requires minimal maintenance.
