Reayon Pneumatic AKH Series Pneumatic Check Valves: Protect Your Pneumatic System, Stop Backflow, Boost Reliability

Backflow in pneumatic systems is a hidden threat that causes unstable operation and energy waste. Reayon Pneumatic's AKH series one-touch check valves are the perfect solution to eliminate this issue, providing reliable protection for your pneumatic systems.

 Key Advantages

1. Reliable Backflow Prevention

With an ultra-low cracking pressure of only 0.005MPa, air flows freely in the forward direction, while reverse flow is completely blocked. It protects cylinders, vacuum generators and other key components from misoperation and pressure loss, keeping your system running smoothly.

2. Easy One-Touch Installation

No tools required! Simply push the PU tube into the fitting for a secure connection, saving time and labor on installation and maintenance. The compact straight-through design fits easily into any pneumatic line layout, ideal for both new equipment and retrofits.

3. Versatile for All Applications

• Wide working range: Supports -100kPa vacuum to 1MPa positive pressure, compatible with nylon, polyurethane and other common tubing

• Durable construction: PBT body + NBR seal, resistant to wear and aging, works stably in -5℃~60℃ environment

• Full size options: Available for Φ4/6/8/10/12mm tubing, meeting all flow requirements

4. High Flow Efficiency

Large effective flow area ensures low pressure drop and high air flow, maintaining system efficiency while preventing backflow, reducing air compressor load and saving energy.

Typical Applications

• Automated production lines: Prevent backflow during cylinder return stroke

• Vacuum suction systems: Maintain vacuum to avoid workpiece dropping

• Air supply distribution lines: Isolate branch circuits to prevent cross-interference

• Pneumatic fixtures & robotic arms: Ensure stable clamping force for safe operation
