AKH Check Valve

General Features of Check Valves
Unidirectional Flow, Backflow Prevention
Relying on an internal disc or spool structure, it only allows fluid (liquid/gas) to flow in a single direction and automatically closes in the reverse direction, avoiding system pressure loss or equipment damage (e.g., preventing oil backflow from impacting the pump body in hydraulic systems).

Compact Structure, Easy Installation
Small in size, it is suitable for pipeline systems with limited space; common interface types include threaded connections (NPT, G threads, etc.), flange connections, or compression fittings, facilitating quick installation and maintenance.

Sensitive Response, Reliable Sealing
The disc acts rapidly, closing instantly when fluid reverses; sealing materials (such as NBR, FKM, etc.) can adapt to different media (oil, water, gas), reducing leakage risks.

High Pressure Resistance, Suitable for Multiple Working Conditions
Typically made of metal materials (stainless steel, brass, etc.), it can withstand pressures ranging from tens to hundreds of megapascals, suitable for high-pressure systems (e.g., industrial pipelines, construction machinery).

Low Flow Resistance Design, Energy-Efficient
With smooth internal flow passages, it causes minimal pressure loss during fluid passage, improving system efficiency (e.g., reducing air loss in pneumatic circuits).

Corrosion and Wear Resistance
Special materials (such as 316 stainless steel, hardened coatings) can resist corrosive media or high-velocity particle impacts, extending service life (suitable for chemical engineering, marine engineering, and other scenarios).
