API 623 Cast Steel Globe, Stop Check, and Needle Valves

Features & Benefits

• Unique non-rotating stem design is easily adaptable for actuation–with precision Acme threads and burnished finish. Valve suitable for horizontal installation.
• All graphite packed globe valves are dual qualified to API 624 and ISO-15848-1. Stuffing box burnished to fine surface finish.
• Trim: Available in all trim material combinations specified in API 623, as well as custom material combinations.
• All sizes and pressure classes have conical seats to ensure tight shut-off.
• Seat face CoCr alloy hardfaced, ground, and lapped to a mirror finish. Conical seat machined to fine surface finish.
• Body guided disc ensures smooth, robust operation and accurately mates the seating surface of the disc with the surface of the body seat, which is ground and lapped to a mirror finish. When specified by the purchaser, the disc guides are hardfaced to enhance smooth guiding and extend their wear life.
• Body and bonnet castings are precision machined. One-piece bonnet for better alignment, fewer parts.
• Body and bonnet joint accurately machined to the required serrated surface finish. Fully enclosed gasket.
• Gland has two-piece construction for easy alignment.
• Torque arm reduces wear on packing rings, enables better sealing and reduces torque.
• Rotating stem nut is austenitic ductile iron Gr. D-2C serviceable in line. When handwheel is used, thrust bearing arrangements vary depending on valve size and class.
• Impactor handwheels: Globe, stop check, and needle valves require higher closing torques than gate valves with the same seat diameter and pressure class. The most economical mechanism for tight shut-off is the impactor handwheel. Two lugs cast under the wheel strike simultaneous blows and give 3–10 times the closing force of standard handwheels. Impactor handwheels are supplied at manufacturer’s option unless specified by the purchaser.
• End connection flanges in accordance with ASME B16.5
  ASME Classes: 150–300: 1⁄16″  raised face.
  ASME Classes: 600–1500: ¼″  raised face.
  Finish: 125–250 AARH for all valves.
