Introduction to Stainless Steel Flange Stop Valve
Stainless steel flange globe valve is a valve that uses the torque of the valve stem to apply downward pressure to the sealing surface, and relies on the pressure of the valve stem to tightly fit the sealing surface of the valve disc and the sealing surface of the valve seat, thereby preventing the flow of medium or regulating the flow rate. This type of valve is suitable for pipelines with various corrosive media, and has good corrosion resistance and sufficient strength. It is widely used in industries such as petrochemicals, chemicals, electricity, metallurgy, pharmaceuticals, and food.

The main features of stainless steel flange globe valves include:

Good sealing performance: There is no relative sliding between the valve disc and the sealing surface of the valve body, with minimal wear and scratches, ensuring good sealing performance.
Simple structure: Manufacturing and maintenance are relatively convenient, and the valve disc moves in a straight line along the centerline of the fluid. The structure is 25% simpler than gate valves.
Wide applicability: Suitable for cutting off or connecting pipeline media in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries with nominal pressure PN1.6~16MPa and working temperature -29~550 ℃.
The working principle of stainless steel flange globe valve is based on the movement form of the valve stem, which has two types: lifting rod type and lifting rotating rod type. The lifting motion of the valve stem causes the valve disc to move along the centerline of the valve seat, thereby controlling the flow of the medium. When the valve stem rises, the valve disc separates from the valve seat and the medium flows; When the valve stem descends, the valve disc tightly adheres to the valve seat, and the medium is cut off
