Alloy Steel Valves

WDL Valve alloy steel valves are used for elevated-temperature, high-pressure and demanding industrial service in power generation, refining, petrochemical, steam and process piping. Available designs include ball, gate, globe, check, butterfly and special-purpose valves in cast and forged alloy steel grades.

Selection guidance: Common chromium-molybdenum materials are selected according to the required pressure-temperature rating, creep resistance, welding procedure and applicable piping specification. Body, bonnet, trim, bolting, hard-facing and packing must be reviewed as a complete assembly; specifying only the body grade is not sufficient for severe temperature or cyclic service.

Standards and RFQ data: Valves can be supplied to applicable API, ASME, ASTM, ISO and project specifications. Send valve type, size, class, material grade, medium, design and operating temperature, pressure, connection, trim, leakage, NDE, heat-treatment and documentation requirements.
