CDC Pneumatics Check Valves
Reliable One-Way Airflow control for Pneumatic Systems
CDC Pneumatics Check Valves are designed to allow compressed air to flow in one direction while preventing reverse airflow.
Suitable for low-pressure pneumatic applications, vacuum lines and industrial air piping systems, CDC check valves help maintain stable airflow and protect pneumatic circuits from unwanted reverse flow.
Available in multiple configurations, connection types and tube sizes for factory automation, machinery and general pneumatic applications.

- Easily used in environments where the vacuum line is protected and maintained, and
under low pressure conditions by allowing compressed air entered in one direction
to flow and by blocking air flow in the opposite direction. - Female screw threads in both directions and metal body type (CVFF)

Frequently Asked Questions (FAQs)
A pneumatic check valve allows compressed air to flow in one direction while preventing airflow from returning in the opposite direction.
CDC Check Valves are used for one-way airflow control, reverse flow prevention, vacuum line protection and pressure control in pneumatic systems.
Cracking pressure is the minimum pressure required to open the internal check valve and allow airflow to pass through.
Yes. Selected CDC Check Valves are suitable for vacuum line applications and are designed to help prevent reverse airflow.
No. The CDC catalogue specifies compressed air as the applicable fluid and states that these products should not be used for water applications.
