4V400 Pneumatic Control Valve is part of Kailing's 400 size directional valve family. The catalog page lists 4A410-15, 4A420-15, 4A430C-15 as representative models, with 1/2 in port reference and pneumatic pilot control. Use this page when the buyer already knows the 400 series and needs a focused RFQ instead of the full 4V/4A family overview.

- 4: 400 series
- 10: single-control two-position
- 20: double-control two-position
- 30C/30E/30P: three-position center variants
- Catalog page 139 lists 1/2 in for this series
- No voltage field is used for 4A pneumatic-control variants; confirm pilot configuration and mounting
- G thread
- ZG thread
- NPT thread
Use this focused page
Use this page when the buyer requests 4V400 Pneumatic Control Valve or related models such as 4A410-15, 4A420-15, 4A430C-15. For other 4V/4A sizes, use the matching 100, 200, 300 or 400 series page.
