Frequently Asked Questions
When should I use a globe valve instead of a gate valve?
Use a globe valve for throttling, frequent operation, and precise flow control. Use a gate valve for full open/close isolation with minimum pressure drop.
Are WCB globe valves suitable for steam?
Yes. WCB globe valves with SS 410 trim and graphite packing are standard for steam stop and regulating service up to 425°C (Class 150 WCB).
What sizes do you supply?
1/2" to 12" (DN15–DN300) standard; larger sizes on enquiry.
