GB Standard Stainless Steel Gate Valve – YONCO PN16 to PN160
The YONCO GB Standard Stainless Steel Gate Valve is a highly durable isolation valve designed specifically for mildly corrosive and oxidative environments. Manufactured in strict accordance with the GB/T 12234 specification, this valve utilizes premium austenitic stainless steel components to deliver outstanding resistance against nitric and acetic acids. Covering a wide size range from DN15 to DN800 and handling pressures up to 16.0 MPa, its straight-through, bi-directional flow design ensures maximum efficiency and minimal pressure drop. It is the ultimate choice for critical chemical, petrochemical, and pharmaceutical pipelines operating at temperatures up to 200°C.
Core Features & Advantages
- Superior Corrosion Resistance: Constructed from high-grade austenitic stainless steel (CrNiTi for Type P, CrNiMoTi for Type R), offering exceptional longevity and stability in oxidizing acid media.
- Optimized Flow Dynamics: The straight-through body design allows media to flow in any direction without restricting the pipeline, significantly reducing fluid resistance and preventing pressure loss.
- Low Operating Torque: The perpendicular movement of the gate relative to the flow direction minimizes friction, ensuring a smooth, labor-saving opening and closing operation.
- Versatile Sealing Combinations: Seat sealing surfaces are customizable with PTFE, stainless steel paired with hard alloy, or stellite hard-facing, providing a leak-proof barrier tailored to specific abrasive or corrosive conditions.
- Compact & Efficient Structure: Engineered with a shortened face-to-face dimension to save critical installation space while maintaining robust sealing performance and minimizing erosion when fully open.
