Axial Flow Check Valve (Silent check valve)

Coosai Axial Flow check valve have Streamlined flow path through full-port expanded body avoids turbulence and prevents erosion and vibration. Process downtime and maintenance costs are eliminated. Intelligent use of venture results in static and dynamic performance, axial flow check valve has become the preferred choice for special applications.


1) Design features

Low pressure drop

The full opening flow passage and high-pressure recovery of the venturi-shaped body result in very low pressure loss: reduced operating cost of pumps and compressors.


Horizontal/Vertical installation

Axial flow check valve can been for both horizontal and vertical pipeline installation.


Maintenance Freely

Coosai Axial Flow Check Valve designs use no soft parts and therefore inherently fire-safe. Various other non-return valve designs rely on external devices like counterweights and slam retarders to operate satisfactorily. Those do not allow buried installation, are space consuming and require regular maintenance. The Coosai Axial Flow Check Valve can be buried or installed in locations where space or weight is at a premium. The Coosai Axial Flow Check Valve normally does not require maintenance.
