LC-333ST-LF2-Three piece Forged Carbon Steel Ball Valves

Three piece Forged Carbon Steel Ball Valves,

, ½" ~1½": Full Port, 2": Standard Port, Class 1500, 3000 WOG, Socket Weld x Threaded ends, with TFM4215 seats, Fire-safe per API 607 Graphite stem packing & body joint gasket, LF2 Body & socket weld end cap, TFM1600 thrust washer, 316 SS ball & 17-4 PH stem, HSN (HNBR) stem O-Ring & body O-Ring, with ISO 5211 tapped mounting pad, with Anti-static device, with rugged lockable lever handle.

The LC-333ST-LF2 three-piece forged carbon steel ball valve combines Class 1500 / 3000 PSI WOG pressure rating with LF2 low-temperature body material, fire-safe construction per API 607, and the maintainability of three-piece body design. The LF2 material per ASTM A350 provides controlled low-temperature ductility down to -50°F, making this valve well-suited for outdoor oil and gas installations in cold climates and any service where ambient temperatures may drop below the Charpy impact threshold of standard WCB carbon steel.

Socket-weld inlet and NPT threaded outlet end configuration supports installations where one end connects to permanent welded piping and the other end requires field-serviceable threaded access — a common configuration for instrument-isolation, sample-system, and small-bore process service in oil and gas production and gas processing facilities. TFM4215 seats with TFM1600 thrust washer provide PTFE-based chemical compatibility and bubble-tight shutoff, while graphite stem packing and body joint gasket maintain seal integrity under fire-exposure conditions. ISO 5211 mounting pad, anti-static device, and rugged lockable lever handle complete the standard configuration.
