For a pneumatic ball valve or butterfly valve package RFQ, confirm the medium, pressure, temperature, valve size, connection type, body and seal material, actuator action, fail position, accessory requirements and quantity.
Package accuracy depends on both valve data and actuator control details.
Start from valve and medium data
Confirm whether the project needs a ball valve or butterfly valve, then provide medium, pressure, temperature, size, connection type, body material and seal requirements.
Match actuator action and fail position
The actuator may be double acting or spring return. Spring return packages also need fail-open or fail-close logic confirmed before quoting.
Confirm accessories as a package
Solenoid valves, limit switch boxes, positioners, brackets, couplings and air preparation units should be reviewed together because they affect installation and control.
RFQ files that speed review
Send drawings, photos, old model numbers, valve torque if available, electrical requirements, quantity, target delivery and packaging needs.

Frequently Asked Questions
- FAQ Can buyers request only the actuator?
Yes, but valve torque, mounting pattern and shaft connection are needed to size and match the actuator. - FAQ Can Kailing review a complete valve automation package?
Yes. Send valve and actuator requirements together with photos, drawings or old model information. - FAQ Why does fail position matter?
Fail-open or fail-close determines spring return direction and can affect actuator sizing and safety logic.
