EVI7/9 System Compatibility
The EVI7/9 coil system features a standardized 9mm guide tube bore interface, ensuring compatibility across the entire product range. This design allows for straightforward coil replacement without mechanical modifications to valve bodies, enabling easy voltage changes during machine refits.
Power and Thermal Performance
With 4.8W power consumption and 200mA current draw, this coil operates efficiently in multi-valve systems. The Class F insulation and Class H wire winding provide thermal headroom for continuous duty operation, while the integrated thermal fuse offers protection against abnormal conditions.
Protection and Connections
IP65 protection ensures complete dust exclusion and water jet resistance when used with proper connectors. Available connection options include AMP 6.3×0.8 quick-connect terminals, DIN 43650 connectors, and flying lead versions for various installation requirements.
Applications and Compatibility
Compatible with AMISCO 3/2-way and 2/2-way pneumatic valves, as well as Airtac 4V110, 4V210, 4V410, and 4V440 series valves. Ideal for pneumatic actuator circuits, process control systems, and industrial automation applications in packaging, automotive, food processing, and general manufacturing.
Frequently Asked Questions
Q1: What is the difference between EVI7 and EVI9 designations?
The EVI7/9 designation covers two related coil families sharing the same 9mm guide tube standard. EVI7 and EVI9 refer to coil body sizes (7 and 9 series), both fitting operators with 9mm guide tubes. Ensure physical dimensions and voltage specifications match when ordering replacements.
Q2: Can the AC110V coil be used with 120V AC supply?
Yes, 110V coils typically operate satisfactorily on 100V to 120V AC supplies. However, persistent operation above 120V is not recommended as it increases current draw and coil temperature, potentially reducing service life.
Q3: What does IP65 rating mean for practical use?
IP65 provides complete dust protection and resistance to water jets from any direction when used with proper connectors. This rating does not cover prolonged immersion - for flooding environments, consider IP67 or IP68 rated coils.
Q4: Can coils be replaced independently of valve assemblies?
Yes, the EVI7/9 system allows field-replacement of coils without removing valve bodies. Simply de-energize the coil, release the retention fastening, slide off the old coil, and install the replacement.
Q5: What causes solenoid coil failure and how to extend service life?
Common failures include thermal aging from overvoltage, poor ventilation, or high ambient temperatures. Maximize service life by operating within rated voltage tolerances, ensuring adequate ventilation, and maintaining ambient temperatures between -15°C to +50°C.
