Sizes 1\/4\u2033 to 4\u2033, with threaded (PT, NPT or PF), socket weld (SW) or butt weld (BW) ends to suit your piping.<\/p>\n<p>Made in CF8M (cast 316) stainless steel \u2014 in stock, with CF8 (cast 304) made to order \u2014 it gives full port, quarter-turn shut-off with a lockable manual lever. This is the <b>V-3A<\/b> \u2014 the manual valve. It has no actuator mounting pad. If you want the option of adding an actuator later, say so when you enquire and we will supply the <b>V-3AM<\/b> instead: the same valve with an ISO 5211 mounting pad machined on top. It still ships with a hand lever \u2014 the pad simply sits there until you need it.
