The VA-7150-1001 synchronous, reversible motor-driven actuator provides three-wire incremental control of calves up to ¾-inch (19.05-mm) stroke in HVAC applications. A magnetic clutch accurately positions the valve, allowing the actuator to reliably generate 90 lb (400 N) of minimum force in either direction, securely maintain the shutoff force even if power is removed and dependably sustain a constant load at the end of travel. The incremental controller provides 24 Vac, 50/60 Hz to the up, down and common terminals. It can also be used with the VG7000 series valves for hot water and chilled water systems.
