What is a stainless steel globe valve?

A stainless steel globe valve is a valve in a piping system that completely cuts off or opens fluid flow by the up-and-down movement of a valve disc. It cannot be used to regulate flow; it only controls opening and closing. Its core components, such as the valve body and valve disc, are made of stainless steel (e.g., 304 or 316L), making it highly corrosion-resistant and suitable for applications in chemical and pharmaceutical industries where high cleanliness of the media is required.

Key Features:

Material: Stainless steel (304/316L), corrosion-resistant

Function: Fully open or fully closed, does not regulate flow

Sealing: Forced seal; pressure must be applied to the valve disc when closing

Standards: Complies with GB/T 12235, API 602, and other standards

Working Principle:

The valve disc sealing surface is pressed against the valve seat by the pressure of the valve stem to prevent flow. Turning the handwheel or electric actuator moves the valve disc along the valve seat axis, thus opening and closing the valve.

Applicable Scenarios:

Media: Water, oil, steam, corrosive media (such as nitric acid, acetic acid)

Industries: Chemical, refining, pharmaceutical, industrial, water supply and drainage, fire protection, water conservancy

Temperature: Room temperature to high temperature (some models are suitable for low temperature applications)
