Axial Flow Check Valve


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) Main Standard

Design Standard: API 6D, ASME B16.34

Face to Face Standard: MFR

Connection standard :ASME B16.5, ASME B16.47

Test & Inspect Standard: API 598


2) Technique specification

Nominal Dimension: 2”-64”

Nominal Pressure: Class 150-1500

Connection type: RF,RTJ,FF

Casting Material: CS,SS, DSS, LTCS,Monel,Alloy steel,Aluminum Bronze

3) 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.


Maintenance Freely

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 Axial Flow Check Valve can be buried or installed in locations where space or weight is at a premium. The Axial Flow Check Valve normally does not require maintenance.


Horizontal/Vertical installation

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