The axial design allows for a streamlined flow path around the disc and high pressure recovery, minimising pressure drop across the valve. The efficient design combined with the highly responsive non-slam operation make this valve ideal for high head, critical pump applications. Its optimum designed aerodynamic flow path through the valve results in very low pressure losses. It is also available with the API 6D face-to-face dimensions (Series ZD)

Features & Benefits
- The streamlined internals of the axial check valve range allow for a turbulence free flow path around the disc
- The high capacity, smooth flow path results in low pressure drop across all of the axial type valves
- Noreva axial check valve designs use no soft parts and are therefore inherently fire-safe
- There are no wearing parts, for clean services, making it maintenance free
- The springs are sized according to the flow rates to ensure that the valves are in the fully open position during normal use
- The axial design allows for a streamlined flow path around the disc and high pressure recovery, minimizing pressure drop across the valve
- A short stroke length provides the quick response required by a non-slam check valve
- Low weight discs, short stroke lengths and spring assistance combine to ensure that it responds quickest to change in flow direction
- The fast response ensures reverse velocity cannot build up to a level that can damage pumps, pipes or related equipment
- Pressure surges can occur when a valve is closed against a moving body of fluid, the quick closure results in a considerably lower pressure peak
