The "One-Way Guard" for Your Pneumatic Systems
Do you have these problems in your daily work?
Air flows backward when the air compressor stops, hurting the pump
Pressure drops in one line, causing other lines to work badly
Air flows back, making your cylinders move slowly or get stuck
Our Reayon Pneumatic Check Valves can fix all these issues easily!
Why Choose Reayon Check Valves?
1. Stop Air Backflow, Protect Your Equipment
This valve only lets air flow one way. It blocks reverse air automatically.
It keeps your air compressor, air cylinder and air tank safe from damage caused by backflow.
2. Pre-Coated Thread Sealant, No Extra Tape Needed
The thread is pre-coated with sealant. You do not need to use extra Teflon tape.
Just screw it in, and it seals tightly. It stops leaks and prevents the thread from getting loose when the machine vibrates.
3. Push-to-Connect Design, Easy to Install
With blue quick-connect fitting and male thread, you do not need any tools.
Just push the air tube in, and it seals right away. It saves you time on setup and repair.
4. Strong & Durable for Long Use
The valve body is made of high-quality nickel-plated brass.
It is hard-wearing and not easy to rust. It works well in wet or dusty workshops.
5. Low Air Resistance, No Extra Pressure Loss
The inner path is designed for smooth airflow.
It does not slow down your system while stopping backflow. It works great for most low-pressure air systems.
Where to Use Reayon Check Valves

In air cylinder circuits: Keep pressure stable for smooth cylinder movement
In multi-line air systems: Stop air from moving between different lines
