Aerotec mosadzný spätný ventil G 1/2 palca vnútorný závit 16 bar | 9048063

In a busy workshop, compressed air lines must deliver consistent pressure without backflow contamination. The Aerotec check valve (model 9048063) installs directly into a G 1/2" female thread, allowing air or water to flow in one direction while instantly sealing against reverse flow. Its solid brass body and NBR seal withstand daily use in pneumatic and hydraulic circuits, from air tool manifolds to water dosing systems.

Why choose it

Backflow can damage compressors, contaminate lines, or cause pressure loss. This valve's brass construction offers reliable sealing and long service life, while the NBR seal handles both air and water without swelling. The G 1/2" thread fits standard fittings, making replacement or new installation straightforward.

Ideal use cases

• Preventing backflow in compressed air distribution lines
• Protecting pumps and compressors from reverse flow
• Water and neutral liquid circuits requiring one-way flow
• Pneumatic control systems and tool connections

Good to know

The valve can be mounted in any orientation, simplifying layout in tight spaces. For best performance, ensure the medium is clean and compatible with brass and NBR. Regular inspection of the seal is recommended in high-cycle applications.
