3-way normally open valves are offered in two styles to fit your application requirements. Pneumadyne's "0" Series valve, part number H0-31-4, features a swivel input port to accommodate critical alignment. The "11" Series, part numbers begin with H11, have a swivel output port as well as push-in connections to ease tubing installation. Durable nylon toggles are retained by a specially designed roll pin which extends service life and will not fall out.
