Electric Actuator SAMSON Type 3374

Electric Actuator SAMSON Type 3374

The Electric Actuator SAMSON Type 3374 is designed for all industrial applications. This actuator is a linear motion device ideal for valve sizes ranging from micro-flow valves to 6″ globe control valves.

The thrust output of the actuator for both extending stem and the retracting stem is limited to a maximum depending on the exact model.

Application

• Electric Actuator for Plant Engineering and HVAC
• Desalination
• Tire Vulcanization

Features

• Compact and simple actuator design to fit perfectly with the compact and simple valve design
• Easier to transmit power over longer distanced compared to pneumatic and hydraulic
• Ideal for low ambient temperature applications
• Motor switched off by torque-dependent limit switches to prevent overloading
• Thrust up to 2.5 kN
• Optionally with fail-safe action for the version with electric override

Three-step version

• Power supply: – 230 V with 50/60 Hz – 24 V with 50/60 Hz
• Synchronous motor with maintenance-free planetary gear
• Additional electrical equipment: 1-Mechanical limit contacts 2-Resistance transmitters

Version with digital positioner

• Power supply: – 85 to 264 V with 47 to 63 Hz – 24 V with 47 to 63 Hz and DC
• Stepper motor with maintenance-free planetary gear
• All function settings performed using a rotary pushbutton on the actuator
• Backlit LCD
• Additional electrical equipment:1- Mechanical/electronic limit contacts 2- RS-485 module for Modbus-RTU communication
• Settings performed in TROVIS-VIEW

Special version with the three-key operation

• The actuator is not operated using the rotary pushbutton. Instead, keys on the cover are used for the operation.
• This actuator version can be operated without having to remove the housing cover.

Principle of operation

The electric actuator consists of a reversible motor and a maintenance-free planetary gear with a ball screw drive. The motor is switched off by torque-dependent limit contacts or in case of overload.

What is the Actuator?

An actuator is something that converts energy into motion. It also can be used to apply a force. An actuator typically is a mechanical device that takes energy — usually energy that is created by air, electricity or liquid — and converts it into some kind of motion. That motion can be in virtually any form, such as blocking, clamping or ejecting. Actuators typically are used in manufacturing or industrial applications and might be used in devices such as motors, pumps, switches, and valves.
