Cast Flow Valves – Technical profile of a check valve manufacturer

Cast Flow Valves S.L. is a manufacturer focused on check valves. The official product structure includes dual plate check valves, ball check valves and nozzle check valves for pumping stations, networks, viscous fluids and desalination plants.

The company states that it produces valves based on its own design and provides technical support related to valve selection and application.

Main product categories include:

  • dual plate check valves,
  • ball check valves,
  • nozzle check valves,
  • flanged check valves,
  • check valves for water networks,
  • check valves for desalination and pumping systems.

Dual plate check valves are compact non-return valves with two spring-assisted plates. They are used where short face-to-face length, quick closing and reduced reverse-flow effects are required.

Ball check valves are suitable for wastewater, viscous fluids and services where the moving element must tolerate suspended solids better than conventional hinged designs.

Nozzle check valves are used in pumping and desalination systems where dynamic response, reduced slam and controlled closing behaviour are important.

Check valve selection should include:

  • flow rate,
  • minimum flow velocity,
  • reverse flow velocity,
  • cracking pressure,
  • horizontal or vertical installation,
  • water hammer risk,
  • pressure drop,
  • body and disc material,
  • elastomer or metal seat,
  • maintenance access.

For water network engineers, pumping station designers and desalination engineers, Cast Flow valves should be selected according to hydraulic behaviour, not only nominal diameter.

Cast Flow Ball Check Valves Cast Flow ball check valves are designed for use in clean water, wastewater, and viscous fluid lines. The check mechanism consists of a free-moving ball that responds to differential pressure, sealing against the seat when flow decreases or reverse pressure occurs. No actuator is required for operation. Versions and...

Cast Flow Nozzle Check Valve The Cast Flow Nozzle is an axial flow check valve with a short-stroke disc and return spring. The nozzle-type geometry channels flow through a Venturi effect, reducing pressure drop compared to conventional swing or dual plate designs, depending on body size and configuration. Operation is driven by differential pressure; no...

Cast Flow Foot Valve with Check Valve Function The Cast Flow foot valve integrates a check valve with a suction strainer basket. It is installed at the pump suction line inlet to prevent ingress of large solids and to maintain pump priming after shutdown. The assembly is not intended as a process filter; the basket retains coarse debris, while fine...

Cast Flow Axial Disc Check Valve The Cast Flow Axial Disc Check Valve is designed for axial disc movement with a return spring. Flow remains aligned with the pipeline axis, and the short disc travel enables rapid closure when flow decreases or reverses. This configuration is primarily used to limit reverse flow and mitigate hydraulic shock (water hammer)...
