Axial flow
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.
Design
Valve design to API 6D/ASME B16.34.
All valves are available with any international flange standard.
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
Unlike most traditional swing check valves, VERVO axial check valves are ideal for both horizontal and vertical pipeline installation.
Maintenance Free
The VERVO 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 COTECH Axial Flow Check Valve can be buried or installed in locations where space or weight is at a premium. The COTECH Axial Flow Check Valve normally does not require maintenance.

| Operation method | The valve clack is automatically opened and closed under the medium force. |
| Application fields | Water, steam, petroleum, natural gas, etc. |
| Other remarks 1 | The sealing faces of valve seat and valve clack are build-up welded with hard alloy to improve the erosion resistance and extend the service life of valve. |
| Other remarks 2 | Streamline flow pass, no bypass of medium, small valve flow resistance, and energy saving |
| Other remarks 3 | Suitable for medium backflow prevention in pipeline or device |
| Other remarks 4 | The floating valve clack structure is adopted to automatically compensate the error caused by wearing during installation and operation, to ensure the tight mating of sealing faces and improve the sealing performance. |
| Other remarks 5 | Due to the short opening and closing travel and the automatic resetting without impact, the valve can be fully opened with a small flow rate, and the closing time can be short. |
