What is a threaded / socket weld ball valve?

It is a quarter-turn rotary valve that uses a perforated, pivoting ball to control fluid flow in pipelines. It is opened or closed by rotating the handle 90 degrees.

What is the difference between threaded and socket weld ends?

Threaded (NPT) ends allow quick installation and removal without welding, ideal for systems requiring frequent maintenance. Socket weld ends provide a permanent, leak-proof joint that is stronger and better suited for high-pressure applications.

What sizes and pressure ratings are available?

SHIELD offers threaded / SW ball valves from 1/4" to 4" (DN8-DN100) with pressure ratings of 1000WOG, 2000WOG, 3000WOG and Class 800.

What body materials are available?

WCB, stainless steel (CF8/CF8M), forged steel and brass are available, with balls in stainless steel 304/316 or chrome-plated brass, and seats in PTFE, reinforced PTFE, RPTFE or metal.

What is the working temperature range?

Depending on the seat material, the valves operate from -196°C to 450°C. PTFE seats are typically used from -20°C to 180°C, while metal seats extend to 450°C.

Is a fire-safe design available?

Yes. Fire-safe designs meeting API 607 and ISO 10497 are available on request with secondary metal sealing to ensure valve integrity in case of fire.

How do you guarantee product quality?

Every valve is hydrostatically and pneumatically tested to API 598, ISO 5208 and EN 12266-1 before shipment, and is supplied with material certificates, test reports and compliance documentation.
