COMMERCIAL CONTROLS Pneumatics

Pneumatic Valve Actuators • Accurately positions steam or water valve modulating plugs in response to a pneumatic signal from a controller • Rolling and molded synthetic rubber diaphragm design provides a constant effective area throughout actuator stroke • L38-317 Exposed Yolk Actuator has a universal valve mounting design with an integral stroke position indicator providing

visual reference for valve position, replaces older style V-3001 model • L38-318 Compact Actuator is ideally suited for 1/2" and 3/4" valve applications with restricted mounting space and a single set screw design provides easy assembly and field mounting to valve bonnet WARNING: Cancer and Reproductive Harm - www.P65Warnings.ca.gov
