◆ Valve body material:

Stainless steel, cast steel, carbon steel, forged steel

◆ Manufacturing standards:

"GB; ANSI;" JIS

◆ Product Overview:

Concealed stem gate valves are used in devices that can be used for regulation and throttling.

◆ Working principle:

By rotating the valve stem, the threads between the valve stem and the gate plate undergo relative motion, thereby driving the gate plate to move up and down within the valve body. When the gate rises, the valve opens and the medium can flow in the pipeline. When the gate descends and tightly adheres to the valve seat, the valve closes, preventing the medium from passing through. During the closing process, a certain sealing specific pressure will be formed between the gate and the valve seat to ensure the sealing performance of the valve.
