LIMITORQUE L120 Series

Flowserve Limitorque L120 series multi-turn actuators have a solid record of performance and reliability in many industries, including commercial and nuclear power, oil & gas refining and distribution, and water/wastewater treatment.

Limitorque L120 Series 

multi-turn actuators have a solid record of making valve control easier in a wide variety of demanding applications. Proven performers under the most challenging circumstances, L120 actuators are ideal for valves requiring rotary or linear movement.

With in unit sizes, L120 electric actuators make it easy to meet or exceed your requirements for positive, dependable, valve actuation. Whether used with gate and globe valves, penstocks, or sluice gates, versatile L120 series actuators operate without modification in any rising or non-rising stem application for linear-action valves.

The L120 series is available in nine sizes covering torque requirements to 60 000 ft-lbs. (81 349 Nm) and thrust requirements to 500 000 lb (2 224 kN) When combined with HB worm gear operators, L120 actuators can also be used to control butterfly, ball, and plug valves, as well as damper drives, flop gates, or any other device which requires rotary movements.

Features

• Aluminum and ductile iron housings offer durability

• Available in weather proof, submersible and explosion-proof construction for the most demanding environments

• Anti-friction bearing supported alloy steel worm shafts with bronze worm gears provide years of reliable operation

• Manual declutching disconnects the motor from the drive train for handwheel operation. Automatic clutching to motor operation occurs when power is applied.

• Torque overload protection

• Position control via geared limit switches that are in step with valve disk position, whether in motor or manual operation

• Actuators connect with most network protocols through the UEX electronic controls package
