This document provides dimensions and technical details of the EL electric actuator, which uses worm and wormwheel reduction gearing to provide tight positioning control and the self locking feature necessary for controlling larger valves, in particular butterfly valves. The actuator includes manual overrides, mechanical end position stops, and position indication.
This document provides a technical datasheet for the Emerson TM5.103 EL series of electric actuators. These devices utilize worm and wormwheel reduction gearing to ensure tight positioning control and self-locking features, making them suitable for controlling larger valves such as butterfly valves.
The datasheet lists specific dimensional data (A through W2) for various models ranging from EL55 to EL800. It also outlines general specifications including nominal rotation of 90 degrees, IP65 enclosure rating, and operating temperature ranges from -20°C to +70°C.
| Nominal Rotation | 90° ±3° |
|---|---|
| Enclosure Rating | IP65 (IP67 optional) |
| Temperature Range | -20°C to +70°C |
| Life | 50,000 cycles minimum |
| Limit Switches | 4x SPDT V3 micro switches |
| Torque Switches | 2x SPDT V3 micro switches |
| Stall Protection | By thermostat in motor windings |
The nominal rotation is 90 degrees, factory set to ±3 degrees.
These electric actuators are specifically designed for controlling larger valves, particularly butterfly valves.
The actuator has a minimum rated life of 50,000 cycles.
The minimum required rating for the customer switch or contactor is 16Amp.
