  • Valworx 581850 electric actuator uses power-to-open and power-to-close, stays in last known position with loss of power. On receipt of a continuous voltage signal, the motor runs and via a rugged all metal gear drive rotates the output drive 90°. The motor is automatically stopped by internal cams striking limit switches. On receipt of a reversing continuous signal, the motor turns in the opposite direction reversing the output drive position.

    These electric actuators are typically used where flammable gases may be present. Automate quarter turn ball valves, butterfly valves or dampers. Valve mounting using standard ISO5211 multi-flange mounting and double square drive. Unique integral motor/housing design provides higher torque in a very small package.

    Actuators are tested to rigorous UL and CSA standards and certified by CSA per above. Two auxiliary dry contact limit switches are provided to confirm open and closed valve position. Thermostatically controlled anti-condensation heater will help protect actuator against damage from condensation.

    Wiring connection is via two 1/2" NPT threaded ports using Exp rated connectors or pipe (not included).
