Description du produit<\/h2>\n

This 2-piece pneumatic ball valve pairs our V-2AM direct-mount valve with a rack-and-pinion air actuator \u2014 double-acting (DA) or spring-return (SR). The valve body, cap and ball are cast 316 stainless steel (ASTM A351 CF8M), full port on every size, rated 1000 WOG, with PTFE seats. A quarter-turn of the actuator opens or closes the line in under a second.<\/p>\n

The ISO 5211 mounting pad is cast into the valve, so the actuator bolts straight on \u2014 no bracket, no coupling to fabricate. Female PT threads are in stock, sizes 3\/8\u2033 to 4\u2033 (DN10 \u2013 DN100); NPT and PF can be made to order. Need more end options like socket weld or butt weld? See the 3-piece air actuated ball valve<\/a>. Prefer a hand lever? See the manual two-piece ball valve<\/a>, ou parcourir tous les pneumatic ball valves<\/a>.<\/p>\n
