Valvcon ADC low-temperature actuators

Valvcon ADC low-temperature actuators are suitable for remote solar-powered installations and for on/off duty and proportional applications where extreme cold temperatures exist. These rugged, compact, quarter-turn electric actuators have an operating temperature range down to –40ºF without requiring an internal heater. The battery can be automatically recharged at temperatures as low as –20ºF and has an operating life of up to 5 yr. The actuators can handle torque requirements up to 3,000 in.-lb, yet they weigh only 31 lb. Standard features include hardened-steel gears, standard ISO 5211 mounting interfaces, stall protection, and a sleep/wake mode to preserve battery power. Optional features include control packages, an electronic holding brake, serial I/O capability, and fully adjustable switches. The inclusion of signal-fail position options, switch-selectable power loss position, onboard manual control, and battery status indicator can save time during both set-up and general maintenance.
