INTRODUCTION

EA-multi tum actuators have the ability to shut off/on the all kind of valves. It can also be installed on a variety of gearboxes.  EA actuators are designed for different speeds and torques to resolve all existing needs.

FEACHURE

• Large information-rich backlit display.
• Valve position monitoring during power loss through simple and absolute encoder.
• Enhanced reliability through solid state controls; reduced internal wiring; simplified torque sensor.
• To be use an innovative method to drive the electrical motor to control the startup current and temperature of solid state.
• Detachable thrust bases across the entire range.
• Configurable data logger functionality, including service alarms.
• Plug & socket option available.
• Use of high quality color display.
• Use of anti-earthquake protection system.
• Launch the engine using an innovative method.
• Strong body against explosion.
• To be use the RS485 protocol between all of circuits.
• Configurable service alarms. Toughened glass screen plus optional environmental shield.
• Up even when mains power is not available; the actuator can be configured and interrogated by using power from its display back-up battery.
• Thrust base design separable for all sizes.
• Simplified control components.
• High immunity from spurious signals.
• The invention of a method for measuring the valve position from +∞ to -∞ with an
• accuracy of 1 degree without the need for electricity.
• Use of the Modbus and Fieldbus network control system
• 112G Ex d IIC T4 Ta = -20°C to +70°C

TECHNICAL DATA
