Product Specifications

Technical details and manufacturing context for Actuator (Pneumatic/Servo)

Definition

An actuator is a critical component of the Aseptic Filling Valve Assembly that provides the precise mechanical force needed to open, close, or modulate the valve during sterile filling operations. It ensures accurate positioning and movement control to maintain aseptic conditions while handling liquid products. The actuator is available in two primary types: pneumatic and servo. Pneumatic actuators use compressed air to create linear or rotary motion through pistons or diaphragms, while servo actuators use electric motors with feedback control systems for precise positioning. Both types convert energy into mechanical movement to operate the valve mechanism. The actuator is designed for use in food manufacturing environments, particularly in aseptic filling systems where hygiene and precision are paramount. Materials on file include stainless steel (316L), aluminum alloy, and engineering plastics such as PTFE and PEEK. Key parameters include operating pressure (1.0–1.6 MPa), supply voltage (24 V DC ±10% for servo actuators), control signal (4–20 mA per IEC 60381), stroke length (15–60 mm), positioning accuracy (±0.05% for servo actuators), response time (0.5–2.0 s), operating temperature (-40–85°C per IEC 60721-3-4), ingress protection (IP54–IP65 per IEC 60529), body material (316L per ASTM A240), and weight (5–25 kg). These values are directory reference ranges and must be confirmed for the specific model and application. Always verify model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

Pneumatic actuators operate by converting compressed air pressure into mechanical motion. Air is supplied to a piston or diaphragm, creating linear or rotary movement that opens, closes, or modulates the valve. Servo actuators use an electric motor with a feedback control system, such as an encoder or resolver, to achieve precise positioning. The control signal (typically 4–20 mA) commands the desired position, and the feedback loop adjusts the motor to maintain accuracy. Both types provide the force and movement required to operate the valve mechanism in aseptic filling systems.

Frequently Asked Questions

What is the operating pressure range for this actuator?

The directory lists an operating pressure range of 1.0–1.6 MPa. Confirm the exact range for your specific model with the manufacturer.

Does the actuator require a supply voltage?

Servo actuators require a 24 V DC supply voltage (±10%). Pneumatic actuators do not require an electrical supply for operation, but may need it for position feedback or control if equipped.

What control signal is used for servo actuators?

Servo actuators typically use a standard analog control signal of 4–20 mA, per IEC 60381. This signal commands the desired valve position.

What is the operating temperature range?

The directory lists an operating temperature range of -40 to 85°C, per IEC 60721-3-4, which is extended for aseptic environments. Verify the range for your application with the manufacturer.
