Product Specifications

Technical details and manufacturing context for Solenoid/Piezoelectric Actuator

Definition
This actuation component is used in dosing valves and injectors to convert electrical control signals into mechanical motion. It operates on either electromagnetic (solenoid) or piezoelectric principles, generating linear or rotary movement that opens, closes, or modulates fluid flow. The actuator is the primary mechanism for achieving precise metering of liquids or gases in industrial applications, such as fuel injection, chemical dosing, and process control. Solenoid versions use a coil that, when energized, creates a magnetic field to move a ferromagnetic plunger. Piezoelectric versions rely on the inverse piezoelectric effect, where an applied voltage causes dimensional changes in piezoelectric ceramics, producing precise displacement. Both types provide fast response and high repeatability, essential for accurate dosing. The component is typically housed in stainless steel (316L) and includes electrical steel laminations and copper wire for the solenoid coil, or piezoelectric ceramics (PZT) for the piezoelectric version. Key parameters include operating pressure (1.0–1.6 MPa), stroke length (0.5–2.0 mm), response time (1–5 ms), positioning accuracy (±0.05 mm), supply voltage (24 V DC ±10%), power consumption (5–15 W), operating temperature (-40 to 85 °C), ingress protection (IP54–IP65 per IEC 60529), and weight (0.5–2.5 kg). These values are reference ranges and must be verified for the specific model and application. The actuator interfaces with a valve body or injector assembly, and its mounting design depends on the weight and stroke requirements. When selecting, consider the required flow capacity, response time, and environmental conditions. Always confirm model-specific specifications and applicable standards with the legal manufacturer or supplier before procurement.
Working Principle
Solenoid actuators operate by energizing a coil to create a magnetic field that moves a ferromagnetic plunger. Piezoelectric actuators use the inverse piezoelectric effect where applied voltage causes dimensional changes in piezoelectric materials, generating precise displacement. Both convert electrical input into mechanical output to actuate valve mechanisms.

Frequently Asked Questions

What is the difference between solenoid and piezoelectric actuators?

Solenoid actuators use a magnetic field generated by a coil to move a plunger, while piezoelectric actuators use the deformation of piezoelectric ceramics under voltage. Solenoids are typically simpler and lower cost, while piezoelectric actuators offer faster response and finer positioning accuracy.

What are the typical operating pressure and temperature ranges?

The operating pressure range is 1.0–1.6 MPa, and the operating temperature range is -40 to 85 °C. These are reference values; always verify for the specific model.

What standards apply to this actuator?

Relevant standards include IEC 60529 for ingress protection, and ASTM A240 for the 316L body material. Compliance must be confirmed with the manufacturer.

How do I select the right actuator for my application?

Consider required stroke length, response time, positioning accuracy, supply voltage, power consumption, and environmental conditions. Verify that the actuator's specifications meet your system requirements, and consult the manufacturer for application-specific guidance.
