Series 70 Electric Actuator
Series 70 Electric Actuator
The Series 70 is a compact, quarter-turn electric actuator designed for rotary valve and damper control. Flexible deployment across a wide range of torques, offering up to 18,000 in-lb (2,034 Nm) and compatibility with 120/230 VAC or 24V AC/DC. UL, CSA, and CE certifications ensure compliance with global standards, making it a reliable choice for automation systems.
Series 70 Electric Actuator
Reliable Ingress Protection
The Series 70 actuator features a durable die-cast aluminum housing with a polyester coating and O-ring sealed cover. Rated Type 4/4X, IP65/IP67, it resists moisture and demanding environments. An optional integrated heater helps prevent condensation, making it suitable for outdoor and industrial use.

High Visibility Position Indicator
Actuator enclosure is hard anodized with an external polyester coating finish. The local mechanical indicator is UV resistant and suitable for outdoor applications. The stainless-steel actuator cover bolts are captive to prevent loss during field maintenance. The cover uses an O-ring seal to avoid moisture ingress and prevent internal corrosion.
