L120 Series actuators operate without modification in any rising or non-rising stem application for linear action valves. The actuators meet rigid safety requirements and are available in weatherproof, explosionproof, and submersible configurations. The actuators are compatible with a wide range of control options from stand-alone units with local pushbutton to open standards-based DDC-100 networks with up to 250 actuators.
The actuators are designed with integral control packages including plug-in interconnect boards that increase control functionality for stand-alone or networked units. Durable torque overload is provided in both directions of travel.
Advantages
The L120 is at home in the most modern process control environments. It is compatible with a wide range of control options — from stand-alone actuators with local controls to open-standards-based, direct-to-host DDC networks with up to 250 actuators.
The L120 series can be directly coupled with valves for torque-only applications. For thrust applications, a separate thrust base is used for the L120-10 through -85.
Rising stem valves may be operated by an L120 coupled to bevel gear operators. Thrusts up to 147420 N and torque up to 10850 Nm can be accommodated.
The L120 series may be coupled to a worm gear reducer for operation of quarter-turn valves such as butterfly, balls, plugs, and dampers.
