ProMation Engineering’s P2-13 Series Quarter-Turn Electric, Non-Spring Return Actuators feature a rugged, industrial-grade design for use with all ball and butterfly valves or dampers requiring higher torque outputs from 800 in. lbs. to 40,500 in. lbs. The series features a self-locking hardened steel drive train for smooth operation, mechanical end of travel stops, and patented clutch-free manual override for single-handed positioning of the actuator. The actuators include an integrated position indicator, two auxiliary switches, an internal low-power anti-condensation heater, and cast-aluminum, polymer-coated housing with two three-fourth-inch conduit connections that are rated NEMA 4X for safe exposure to high-pressure hosing and corrosion resistance. Proportional control units accept a range of control signals while generating multiple feedback signals and are easily installed, calibrated, and adjusted in the field. The actuators are available for 24 VAC/VDC, 120/230 VAC or single-phase and complete three-phase offerings. They comply with ISO 5211 and ARRA, conform to AWWA C540 standards, and are certified to CSA 22.2 standards, including ANSI/UL 50 and ANSI/UL 429. – promationei.com
