Engineered for heavy-duty industrial applications, this 4-inch Class 150 CF8 (304) Stainless Steel Gate Valve is strictly manufactured to API 600 and ASME B16.34 standards. Featuring a robust Outside Screw and Yoke (OS&Y) rising stem and a precision-machined solid wedge, this valve provides exceptional zero-leakage shut-off capabilities for high-pressure pipelines. Designed for durability in demanding environments, it is an ideal isolation solution for petrochemical, water treatment, and corrosive process systems.

🏭 Engineering & Compliance Highlights:

  • Premium Material: High-grade CF8 (ASTM A351) stainless steel casting for superior corrosion resistance.
  • Structural Integrity: OS&Y rising stem and bolted bonnet design ensure maximum safety and ease of maintenance.
  • Global Compliance: Built to API 600, ASME B16.5, and API 598 testing standards for guaranteed performance.
  • Full-Bore Flow: Straight-through design minimizes turbulence and pressure drop for efficient fluid transmission.
