Questions about this product
- What does this air check valve actually do in my system?
- It lets compressed air flow one way and blocks it from going back. The spring snaps shut fast to stop reverse airflow. People use it to protect compressors and dryers from backflow when several units share a line.
- Which port size should I pick, 6mm through 12mm?
- Match the port to your tubing and fitting size. The AKH series runs from 6mm up to 12mm. Bigger ports flow more air with less pressure drop, so size it to your line, not smaller.
- What pressure and temperature can it handle?
- It works from 0 to 1.0 MPa, which is about 145 psi. The rated temperature range is -5 to +80 degrees C. Stay inside those limits and the NBR seal holds up well in normal shop air.
