6″ Class 150 WCB Cast Steel Globe Valve, Flanged RF, API 623

Engineered for heavy-duty flow regulation, this 6-Inch (DN150) Class 150 Globe Valve is manufactured from premium ASTM A216 WCB Cast Carbon Steel. Designed with a robust bolted bonnet (BB) and an outside screw and yoke (OS&Y) mechanism, it ensures structural integrity and easy operation in demanding industrial pipelines. Strictly conforming to API 623 and BS 1873 standards, its precision-machined plug and seat deliver exceptional throttling characteristics and reliable shut-off for oil & gas, power generation, and refining applications.

🏭 Engineering Highlights:

  • Design Standard: Fully compliant with API 623, BS 1873, and ASME B16.34.
  • Body Material: ASTM A216 WCB (Heavy-wall cast carbon steel for high durability).
  • Flow Control: Conical or flat plug design for precise throttling and reduced turbulence.
  • Connection: Raised Face (RF) Flanged ends to ASME B16.5.

🌐 Global Standards & Custom Manufacturing

Beyond standard API 623 / BS 1873 specifications, our cast steel valve division is fully equipped to manufacture according to DIN, JIS, and GOST standards. We offer comprehensive OEM services, including custom face-to-face dimensions, specialized trim materials (e.g., Monel, Hastelloy), and NACE MR0175 compliance for sour gas environments.

⚡ Automation & Actuation Ready

While this 6-inch model is supplied with a heavy-duty impact handwheel for manual operation, our cast globe valves can be engineered with an ISO 5210 top flange or bevel gear operator. We provide fully assembled and tested automated packages:

  • Pneumatic Actuators: Linear diaphragm actuators for rapid, fail-safe throttling control.
  • Electric Actuators: Multi-turn smart electric actuators (AUMA, Rotork equivalent) for precise remote flow regulation.
  • Accessories: Smart positioners, limit switches, and filter regulators tailored to your exact EPC specs.
