ProMation Engineering (Brooksville, FL) offers P1 series quarter-turn electric, non-spring return actuators, which feature a compact industrial grade design for use with all ball and butterfly valves or dampers requiring torque outputs from 135 to 445 in. lbs., a self-locking hardened steel drive train for smooth operation, and patented clutch-free manual override.
Available in on/off, bump/jog, and proportional control models, the actuator’s standard features include an integrated position indicator, two auxiliary switches (rated at 3A 250V Max), an internal low-power anti-condensation heater, and cast aluminum polymer coated housing with two ½” conduit connections that is rated NEMA 4X for safe exposure to high pressure hosing and corrosion resistance.
Proportional control units accept a wide range of control signals while generating multiple feedback signals and are easily adjustable in the field. The actuators are available for 12 VAC/DC, 24 VAC/DC, 120 VAC, or 230 VAC supply voltages, are ISO 5211 compliant, offer multiple mounting patterns (FO3/F05/F07), and are certified to CSA 22.2 standards including ANSI/UL 50 and ANSI/UL 429.
