Description du produit<\/h2>\n

This pneumatic 3-way vacuum ball valve automates the switching of a vacuum line. A rack-and-pinion air actuator rotates the ball a quarter turn on a signal from your PLC or solenoid, diverting one vacuum pump between chambers, or venting a line \u2014 no one has to stand at the valve. The body is cast 316 stainless steel (ASTM A351 CF8M) with a polished surface and PTFE seats, on NW (KF) vacuum flanges in NW40 (1-1\/2\u2033) and NW50 (2\u2033).<\/p>\n

The ball is available L-port or T-port \u2014 L-port connects one outlet at a time, T-port can connect two outlets together or merge flow. Prefer to switch it by hand? See the manual 3-way vacuum valve<\/a>. For straight (2-way) vacuum lines, see the NW50 pneumatic vacuum ball valve<\/a> or the larger Vanne pneumatique \u00e0 vide ISO-K DN80\/DN100<\/a>, ou parcourir tous les vannes \u00e0 vide<\/a>.<\/p>\n
