What is the difference between screwed and socket weld ends?

Screwed ends (NPT, BSP) use threaded connections suitable for low-pressure applications where disassembly may be required. Socket weld ends provide a smooth bore with the pipe inserted into the valve socket and fillet welded, providing permanent high-pressure connections with no bore restriction.

What pressure class do I need for my application?

Pressure class depends on your system pressure and temperature. Class 800 is common for oil and gas instrumentation. Class 1500/2000 is typical for high-pressure process applications. Our engineering team can recommend the appropriate class based on your specific operating conditions.

Are these valves fire-safe?

Yes, our socket weld and screwed ball valves feature fire-safe design per API 607. They utilize a graphite packing and fire-safe seat material that maintains stem sealing during and after fire exposure, preventing external leakage even when the primary soft seat is damaged.

What is a blowout-proof stem?

A blowout-proof stem features a stem shoulder that engages with the body, preventing the stem from being ejected by system pressure if the gland nut is removed. This is a critical safety feature required by API 608 and ensures operator safety during maintenance.
