axial check valve
An axial check valve is the preferred solution for critical non-return applications such as the protection of rotating equipment and systems where low pressure loss, stable operation and dynamic behaviour are essential.

Main product features
Axial flow
Streamlined flow path through full-port expanded body avoids turbulence and prevents erosion and vibration. Process downtime and maintenance costs are eliminated.
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.
Tight shut-off
Tight shut-off is obtained by means of metal-to-metal sealing. This sealing is not affected by erosive flow.
Non-slam operation
The spring-assisted design ensures ultra-fast closing without backflow and pressure surges, in critical applications such as multi-pump systems.
Easy opening
The low static pressure in the throat area is applied behind the disc and creates a pressure differential over the disc, resulting in easy opening.
Stability
Extremely stable during operation. The axial check valve responds smoothly to changes in flow and remains stable whit it is supposed to be.
Maintenance free
Internal construction is based on the application of sound basic mechanical engineering principles. Consequently, the axial check valve does not require any maintenance.
Special features
- All axial check valves are custom made to meet clients’ specific requirements.
- Fire-safe, cryogenic and sub-sea design.
The axial check valve is selected in preference to the following:
- Swing check valve
