Backflow preventer
HIGH PRESSURE
Swing check valves have lower pressure losses due to their straight passage. They are primarily suitable for horizontal or vertical pipelines flowing through.

Check valves have lower pressure losses due to their straight passage. The wide swinging rattling stroke is associated with a hard folding stop, especially for large nominal diameters. When used in steam or gas pipes or in pipes with pulsating flow, shock absorption can be achieved by air or oil brakes.
The check valves are primarily suitable for horizontal or vertical pipelines flowing upwards.
