A pneumatic actuator package may need a solenoid valve for air control, a limit switch box for open-close feedback, a positioner for modulating control, and brackets or couplings for valve mounting.
Buyers should confirm the control signal, voltage, fail position, valve mounting standard and site environment before requesting a package quote.
Solenoid valves control actuator air
A solenoid valve sends compressed air to the actuator ports. Buyers should confirm voltage, port configuration, connector type and whether manual override is required.
Limit switches provide position feedback
A limit switch box lets the control system know whether the valve is open or closed. Confirm switch type, enclosure, cable entry and site environment.
Positioners are used for modulating control
When the valve must move to intermediate positions, a positioner may be required. This should be confirmed separately from simple open-close control.
Mounting hardware matters
Brackets, couplings, valve shaft data and mounting standards are needed to assemble a reliable package. Photos and drawings help avoid mismatch.
| Parameter | Value |
|---|---|
| Solenoid valve | Voltage, ports, coil connector and manual override. |
| Limit switch | Feedback type, enclosure and cable entry. |
| Positioner | Control signal and modulating requirement. |
| Mounting | Valve top flange, shaft size and bracket data. |
| Air preparation | Clean and stable compressed air for actuator service life. |
Frequently Asked Questions
- FAQ Does every pneumatic actuator need a limit switch?
No. It is needed when the control system must know whether the valve is open or closed. - FAQ When is a positioner needed?
A positioner is used when the valve must modulate, not only open or close. - FAQ What voltage should buyers provide?
Provide the required voltage for solenoid valves, switches or positioners, such as DC 24 V or AC 220 V.
