the Opening and Closing Parts of Stainless Steel Flange Stop Valve Are Plug-Shaped Valve Clack, the Sealing Surface Is Flat Or Conical, and the Valve Clack Moves Linearly along the Center Line of the Valve Seat. the Movement Form of the Valve Stem, (General Name: Concealed Rod), Also Has the Lifting Rotary Bar Type, (General Name: Rising Stem) Stop Valve Refers to the Valve Whose Closing Piece (Valve Disc) Moves along the Center Line of the Valve Seat.
Cut-off Valve, Also Known as Partial Door Curtain, Is the Most Widely Used Valve. the Reason Why It Is Popular Is That the Friction between the Closed Cover Is Small, Which Is Relatively Durable, the Opening Height Is Not Large, and It Is Easy to Manufacture, convenient Maintenance, Not Only Suitable for Medium and Low Pressure, but Also Suitable for High Pressure.
the Closing Principle of Stop Valve Is to Rely on the Pressure of the Valve Bar to Make the Sealing Surface of the Valve Flap Closely Fit with the Sealing Surface of the Valve Seat and Prevent the Medium from Flowing. Stop Valve Allows Only One-Way Flow of Medium, and the Installation Is Directional. the End-to-End Dimension of the Stop Valve Is Greater than That of the Gate Valve, and the Fluid Resistance Is High at the Same Time. during Long-term Operation, the Sealing Reliability Is Not Strong.

Structural Features
Stainless Steel Flange Stop Valve Structure Diagram
1. Advanced Structure, Reliable Sealing, Excellent Performance and Beautiful Appearance. the Steel Degree of the Valve Stem Is Improved, the Noise and Vibration Are Significantly Reduced, and the Service Life and Various Performances of the Valve Are Improved.
2. the Stop Valve Can Be Installed at Any Position of the Pipeline, and the Medium Flows from Bottom to Top.
3. Dn250 Or above Adopts Advanced Multi-Seal, Double Bracket, Guiding Movement (Which Can Greatly Improve the Resistance to Water Hammer Impact), and Medium Entering from the Top, Which Better Solves the Large Opening and Closing Torque of Large Diameter Stop Valve, the Seal Cannot Be Tightly Closed, and the Packing Chamber Runs, Which Effectively Improves the Performance and Application Range of the Valve. (the "off" Torque Is 10% of the Ordinary Valve, and the "Open" Torque Is 3% of the Ordinary Valve).
4. Stainless Steel Stop Valves Is Applicable to Pipelines with Various Corrosive Media, with Good Corrosion Resistance and Sufficient Strength.
5. Alloy Steel Stop Valve Is Suitable for High Temperature Resistant Steam and Oil Pipelines, and Has the Characteristics of High Temperature Resistance.
