I.Product Overview
The E215-16-11D is a multi-turn electric actuator from ABB,designed for controlling gate and globe valves requiring multiple rotations.Its core function is to open and close the valve via a motor,and it supports local and remote control,position feedback,and fault diagnostics.It is widely used in water treatment,power generation,chemical engineering,building automation,and other fields.
II.Model Explanation
E215:
E stands for Electric Actuator.
215:Series model number,often associated with the actuator’s output torque range or size(e.g.,215 may indicate a maximum torque of 215 Nm or be compatible with a specific valve size).
16:
May indicate output speed(RPM)or control signal type(e.g.,a 4-20mA signal corresponds to 16-bit resolution).
Alternatively,it may represent a protection rating code(e.g.,the”6″in IP66 represents dust protection,but this needs to be confirmed in conjunction with other parameters).11D:
11:May indicate a function code(such as support for HART protocol or Modbus communication).
D:May indicate explosion-proof certification(such as ATEX Zone 2)or special configurations(such as dual seal design or low-temperature environment compatibility).
III.Core Functions and Technical Features
Output Performance
Torque Range:The estimated maximum output torque is 215 Nm(subject to confirmation based on model),suitable for small and medium-sized valves(such as DN50-DN200 gate valves).
Speed:Adjustable speed(such as 10-30 RPM)may be supported,allowing parameter settings to match different valve response requirements.
Multi-turn Design:Supports continuous rotation of more than 360°,suitable for valves requiring multiple turns,such as gate valves and globe valves.
Control Method
Local Control:Manually open and close the valve using buttons or knobs on the actuator panel.Remote Control:Supports 4-20mA analog signals or digital signals(such as Modbus RTU/TCP),enabling integration with PLC,DCS,or SCADA systems.
Position Feedback:Provides a 4-20mA position signal or pulse signal,providing real-time feedback of valve opening to the control system.
Protection and Diagnostic Features
Overload Protection:A built-in torque sensor automatically shuts down and issues an alarm when the valve is stuck.
Overheat Protection:Triggers a protective mechanism when the motor overheats,preventing damage.
Fault Diagnostics:Error codes(such as power failure and communication interruption)are uploaded via LED indicators or communication protocols.
Environmental Adaptability
Protection Rating:Possibly IP66(dustproof and waterproof),suitable for outdoor and humid environments.
Operating Temperature:Estimated range is-20°C to+60°C(depending on the model),suitable for most industrial scenarios.
Explosion-proof Certification:If the”D”in the model number indicates explosion-proof,it may support standards such as ATEX and IECEx(e.g.,Ex d IIC T4 Gb).Installation and Maintenance
Modular design:Allows quick removal of motors,control modules,and other components for easy on-site maintenance.
Maintenance-free motor:Utilizes long-life bearings and seals,reducing the need for regular maintenance.
IV.Typical Application Scenarios
Water Treatment and Water Supply
Controls inlet and outlet valves to regulate flow or perform emergency shutoffs.
Example:Regulating the water flow into aeration tanks in sewage treatment plants.
Power Industry
Controls boiler feedwater valves and steam traps to ensure safe system operation.
Example:Regulating turbine bypass valves in thermal power plants.
Chemical and Petroleum
Controls pipeline media transfer valves to prevent leaks or overpressure.
