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.
