Thin, Compact Solenboid Valves

HEA/HEB Series solenoid valves are thin (10 mm) and compact, and deliver a 0.07-Cv flow rate.

Response times are 6 msec when "on" and 7 msec when "off." They come in a standard 0.55-W version and a low-power 0.15-W version. They mount as a single unit, single unit with base piping, or on various types of manifolds. The HEA Series comes in two, three, and four-way with two, three, and five-port configurations, and are available with double solenoids. The HEB Series comes in two and three-way with two and three-port configurations. They can be normally open or normally closed. Port sizes include M3, 10-32 UNF, and 1 /8-in. NPT. All valves have a pressure rating from 29 to 102 psig.
