BS 1873 Flanged RF Carbon Steel WCB Globe Valve

Engineered for precise flow regulation and reliable shut-off, the BS 1873 Flanged RF Carbon Steel WCB Globe Valve delivers exceptional performance in general industrial applications.

Manufactured from high-quality ASTM A216 WCB carbon steel, this valve offers excellent mechanical strength and durability for water, oil, gas, and steam services. Designed strictly to BS 1873 standards, it features a robust bolted bonnet construction and a plug-shaped disc that moves linearly along the valve seat centerline. Equipped with standard Raised Face (RF) flanged connections (ASME B16.5), this globe valve ensures smooth flow control, reliable sealing, and seamless integration into critical piping systems.

Key Features & Benefits

● BS 1873 Standard Compliance: Designed and manufactured strictly to BS 1873 specifications, ensuring dimensional compatibility, structural safety, and reliable performance in global industrial infrastructure.

● WCB Carbon Steel Construction: Crafted from premium ASTM A216 WCB cast steel, providing superior strength, durability, and resistance to high-pressure environments for general industrial media.

● Precise Throttling & Shut-off: The plug-shaped disc moves linearly along the valve seat, with the port change directly proportional to the disc stroke, making it ideal for both precise flow regulation and reliable isolation.

● RF Flanged End Connections: Compliant with ASME B16.5 standards, ensuring easy installation, secure sealing with non-metallic gaskets, and leak-proof performance in standard piping systems.

● OS&Y Rising Stem Mechanism: Features an Outside Screw and Yoke design with a non-rotating rising stem, providing a clear visual indication of valve position and protecting stem threads from media exposure.

● Versatile Operation Options: Available with manual handwheel, bevel gear, electric, or pneumatic actuators to meet diverse automation and manual operation requirements.

FAQ

Q: What is the difference between a BS 1873 globe valve and an API 600 gate valve?
A: BS 1873 globe valves are designed for precise flow regulation and throttling, with a linear disc movement that allows proportional flow control. API 600 gate valves are designed for full open or full shut isolation only, with a wedge gate that does not allow throttling. Globe valves have higher pressure drop but better flow control; gate valves have minimal pressure drop but no throttling capability.

Q: Why choose WCB carbon steel for globe valves?
A: WCB (ASTM A216) is a standard carbon steel casting that offers excellent weldability, good mechanical strength, and suitability for high-temperature services up to 425°C. It is the most cost-effective and widely used material for general industrial valves handling water, oil, gas, and steam.

Q: What does RF (Raised Face) mean for flanged globe valves?
A: RF stands for Raised Face, where the gasket seating surface is raised above the bolting circle. RF flanges are typically used with non-metallic gaskets (like PTFE or EPDM) and are the most common flange type for low to medium-pressure applications, providing reliable sealing with standard bolting.
