Hayward HZSN1 Series Electric Actuators

The HZSN1 Series is a compact, industrial-duty electric actuator designed for ball valves up to 2" requiring ≤ 266 in-lbs of torque. It supports both on/off and proportional control, with proportional models featuring 4-20mA or 2-10VDC feedback output as standard. The lightweight aluminum alloy enclosure is electrostatic coated for NEMA 4/4X/IP67 protection and Class B motor protection.
