Linear Electric Actuators L-250

Description:

Thrust: 250 kgf/550 lbf

Weight: 9.5 kg/21 lb

Motor: 15 W

Mounting Flange(ISO 5210): F07

Feature:

Enclosure:

IP67、NEMA 4X:Water-proof and dust-proof enclosure.

Material:Dry powder coating aluminum alloy.

Position Indicator :

All models are equipped with continuous mechanical position indicator. The external stem visual position indicator provides easily read and instantly available stem position.

Modulating Controller :

Actuator can be operated according to input signal and provide the output signal for feedback.

Input signal:4-20mA, 1-5V or 2-10V.

Output signal:4-20mA or 2-10V.

Adjustable Stroke :

Allow users to adjust actuator’s stroke to match valve stem’s stroke. (Refer to the specifications for stroke range)

Motor :

All models are equipped with DC motor and provide low power consumption, high duty cycle and efficiency.(1500 starts per hour)

Working Conditions :

Ambient temperature:-30℃ to +65℃ / -22℉ to +149℉

The humidity:30% to 95%

Over-thrust Protection :

If the output thrust of the drive exceeds of the drive rating, the actuator will shut off by two-step control. The two-step control is as follows:

First step : If the output thrust of the drive exceeds the rating, power supply will be turned off by limit switches.

Second step : If the limit switches fail, power supply will be turned off by electronic detector. (The function only applies to modulating controller actuator)

Slow-speed operation :

Besides the standard operating speed, if slower operating speed is needed, please contact with our sales person.

Conduit entrance :

standard : 1/2” NPT

option : M20 or 3/4” NPT

Various voltage :

24V AC/DC

110/220V AC
