Descripci\u00f3n del producto<\/h2>\n

This manual 3-way vacuum valve switches a vacuum line by hand. A quarter turn of the stainless lever rotates the ball to divert one vacuum pump between chambers, or vent a line. 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. Need it automated? See the pneumatic 3-way vacuum ball valve<\/a>. For straight (2-way) vacuum lines, see the NW50 pneumatic vacuum ball valve<\/a> or the larger V\u00e1lvula neum\u00e1tica de vac\u00edo ISO-K DN80\/DN100<\/a>, o ver todos v\u00e1lvulas de vac\u00edo<\/a>.<\/p>\n
