Valvole a sfera a 3 pezzi

Stainless 3-piece ball valves with threaded, socket weld or extended butt weld ends. Manual and pneumatic options with a serviceable body for industrial piping.

A three-piece body comes apart without cutting the pipe. Undo the bolts, lift out the centre section, replace the seats, put it back together. On a welded line that matters, because the alternative is a torch.

This category covers our three-piece stainless ball valves across end connections and operation. End options run from PT / NPT / PF threaded (in stock) through socket weld a extended butt weld sized to JIS pipe. Operation is either a manual lever or a rack-and-pinion pneumatic actuator, double acting (DA) or spring return (SR).

Sizes, pressure ratings and end options vary by model. Check the product page for the one you need.
