Collins - Electric Control Valve Actuator with Collins Plastic Control Valves
Collins Instrument Company, Inc. of Angleton, Texas offers an electric actuator for use with its 1/2”, 3/4”, 1” or 2” split body, globe style, plastic control valves. Each standard electric actuator valve package will accept standard analog current and voltage signals. Gear-free design of the actuator provides smooth, highly accurate positioning, with positive position-lock when not in motion.
Collins has designed a Polypropylene mounting adapter for use with this actuator. Through use of a “keeper ring” the adapter easily and securely assembles to Collins standard 10% glass-filled polypropylene valve yoke. All metal valve linkage is contained within this adapter thereby maintaining the total corrosion resistant feature of the entire valve package. This unique adapter allows for easy maintenance and/or retrofitting the electric actuator to existing pneumatic assemblies when such a conversion is necessary.
