Double acting actuators use air pilot pressure to open and air pilot pressure to close. The pilot air is typically controlled by a 4-way or 5-way type manual or solenoid valve.An optional pilot solenoid valve can be mounted directly to the side of the actuator using the standard Namur interface saving time, space and plumbing. The solenoid valve when supplied with the required pilot air pressure will allow electrical operation of the actuator.The hard anodized body and internals together with piston guides and bearings assure high-cycle life and efficiency.  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
