Product Overview

Axial flow check valve is a performance check valve designed in accordance with API 6D and ASME B16.34. Widely used in pipeline systems to prevent liquid backflow hazards and protect mechanical equipment, it not only has the functional characteristics of a general check valve, but also reduces water hammer hazards, noise, pressure drop, and rapid response.


Product Features

1. Open and close without impact, silent.
2. Very low opening pressure and pressure loss, low energy consumption.
3. Both low and high pressures are tightly closed, with zero leakage.
4. Integrated valve body, long-term reliable operation, maintenance free.
5. Compact structure, can be installed horizontally, vertically, and at any angle, and is easy to install.

6. Can be specially designed and manufactured according to user requirements.
