CDC Pneumatics Pilot Check Valves
Integrated Speed Control and Cylinder Position Holding
CDC Pneumatics Pilot Check Valves combine pilot-operated check valve functionality with pneumatic speed control to provide controlled cylinder movement and secure position holding.
Designed for pneumatic cylinder applications requiring intermediate stopping, these valves help prevent unintended cylinder movement when the air supply is interrupted. Selected models also integrate adjustable airflow control for convenient cylinder speed regulation.
CDC Pilot Check Valves are suitable for industrial automation, machinery and pneumatic positioning applications.

- This product combines the pilot check valve and speed controller as one body.
- Capable of freely setting direction for attaching the tube at any angle.
- Capable of a temporary intermediate stop of the cylinder.
- Possible to prevent sagging due to vertical self-load when air is blocked in OFF mode.
PVSC Speed Controller with Pilot Check Valve
CDC PVSC Series combines a pneumatic speed controller with a pilot-operated check valve in one fitting.
It allows cylinder speed adjustment while also helping hold the cylinder at a required position when pilot pressure is removed.
The rotatable fitting design allows convenient tube routing for pneumatic machinery and automation systems.

Frequently Asked Questions (FAQs)
A pneumatic pilot check valve allows airflow during normal operation and blocks airflow when pilot pressure is removed, helping hold a pneumatic cylinder in position.
A standard check valve prevents reverse airflow automatically, while a pilot check valve can be opened using an external pilot air signal when reverse flow is required.
Yes. A pilot check valve can help hold trapped air in the cylinder when the air supply or control signal is removed, reducing unintended cylinder movement.
