Check valves

Check valves are used to protect pipelines or tanks against an automatic (without further energy) and undesired emptying. Often check valves are installed directly after a pump to protect the pump against backward running.

Ball check valve

This type features by its manifold types of connection (coupling nut with inserts on both ends) as well as its easy, tough and favourable flow construction.

• Body material: PVC-U, PP, PVDF

Swing check valve

Special advantages are the complete and  free opening of cross-section for minimum pressure loss and also the user-friendly opening for maintenance.

• DN 20-200
• Body material: PVC-U, PP, PVDF

Wafer check valve

This type, cheap in price has a very short length. For horizontal pipes and mounting directly after a pump, please use the wafer check valve with return spring. For design of pipe the decreased cross section and the space necessary for free disc opening have to be considered.

• DN 32-400
• Body material: PVC-U, PP, PVDF
