Stainless Steel Ball Valves
Stainless steel ball valves give quick quarter-turn shut-off with excellent resistance to corrosion. They're used wherever rust, contamination or aggressive fluids rule out carbon steel and iron.
We supply one-, two- and three-piece SS304 and SS316 ball valves, threaded, socket weld and flanged, including sanitary and ISO-mounting-pad designs for automation.

Frequently asked questions
SS304 or SS316?
SS304 suits water, air and mild chemicals. SS316 contains molybdenum, which resists chloride pitting, so choose it for seawater, coastal sites and most chemicals.
What does 1000 WOG mean?
WOG stands for water, oil, gas. A 1000 WOG valve is rated to 1000 psi (about 69 bar) at ambient temperature. The rating falls as temperature rises.
Why choose a 3-piece valve?
The centre section can be swung out for seat replacement without removing the end pieces from the pipe, which is useful on welded lines.
