The typical application of the motorized electric actuator is represented by the ON-OFF actuation of valves with ISO 5211 flange.
The motorized electric actuator is composed of a reversible synchronous motor functioning with a single phase ac voltage and equipped with a permanent bidirectional magnet and two coils. The clockwise or counter-clockwise direction is ensured by a capacitor producing an electrical 90°dephasing between the two coils.
The available power supply voltages are:
The basic speed of the actuator is indicated in rpm, it is stable and can be selected from 250 up to 500 rpm depending on the supply frequencies.
The speed of an actuator powered at 60Hz is 20% higher than the speed of an actuator powered at 50Hz.
The gearbox has been designed to ensure an optimum lifecycle on the basis of the maximum torque which can be applied to the output shaft.
All wheels are made of metal, bronze bearings are sintered and the output shaft is carbonitrided in order to guarantee a long lifecycle.
The gearbox is supplied with a life-time grease coating.
All fixing screws are in stainless steel.
Positioning is ensured by an electronic board equipped with two limit switches and a capacitor.
The connection is made by means of a 6-terminal connector and a cable gland ensuring the IP protection level.
The input signal is SPST with two wires, ON-OFF with internal relay.
For the electrical connection see the relevant diagram.
Protection level: IP54
Operating temperature: -20° + 70°
When request, mounting kit and heaters shall be used.
For installation it is highly recommended to follow the instruction sheet.
L’attuatore elettrico Enolgas FLAT è stato progettato per essere compatibile e facilmente installato nelle cassette profonde solo 80 mm. Infatti l’attuatore Enolgas FLAT ha uno spessore solamente di 48 mm per le cassette più piccole.
The electric Enolgas FLAT actuator has been designed to fit and be easily installed in cases only 80 mm deep. In fact Enolgas FLAT actuator is just 48 mm thin and suits the smallest case
