FAQ
Q: What does WCB mean in carbon steel globe valves?
A: WCB is the ASTM A216 standard casting grade for carbon steel. It offers excellent weldability, good mechanical strength, and suitability for high-temperature services up to 425°C, making it the most cost-effective and widely used material for general industrial valves handling water, oil, gas, and steam.
Q: Why choose a manual handwheel for a BS 1873 globe valve?
A: Manual handwheel operation provides direct, reliable control without the need for external power sources. It is cost-effective, easy to maintain, and ideal for applications where automated control is not required or where simplicity and reliability are prioritized.
Q: What is the temperature range for a WCB carbon steel globe valve?
A: A WCB (ASTM A216) carbon steel globe valve can typically handle temperatures from -29°C up to +425°C. For continuous high-temperature service above 425°C, materials such as WC6, WC9, or stainless steel are recommended to maintain structural integrity and creep resistance.
