Stainless steel (SS) gate valves are robust flow-isolation devices built to standard industrial specifications. Common materials include SS304 (CF8) or SS316 (CF8M), pressure ratings from Class 150 to 600, sizes ranging from 1/2' to 24'+, and compliance with API 603, ASME B16.34, and API 598 inspection standards. Materials and Construction • Body/Bonnet Material: ASTM A351 CF8 (SS304) or CF8M (SS316); low carbon CF3/CF3M options available. • Design Type: Bolted bonnet, outside screw and yoke (OS& Y), rising stem or non-rising handwheel. • Wedge/Disc: Solid, flexible, or split wedge designed for bi-directional flow isolation. • Gasket & Packing: PTFE, flexible graphite, or spiral-wound SS304/SS316 with graphite. Ratings and Dimensions • Pressure Classes: ASME Class 150, 300, 600 (PN16 to PN64 equivalents). • Size Availability: 1/2 inch to 24 inches (DN15 to DN600) for flanged/welded; smaller threaded (BSPT/NPT) from 1/2' to 2'. • End Connections: Flanged (RF/RTJ as per ASME B16.5), Threaded (BSPP/NPT), Socket Weld, or Butt-Weld. • Design & Test Standards: API 600/603 (manufacturing), ASME B16.10 (face-to-face), API 598 (hydrostatic/pneumatic testing).
