PRODUCT PREVIEW

LACIER Full Port Swing Check Valves prevent backflow in pipelines and are effective in both low and high current pace applications.

The LAcier Full Port Swing Check Valves can be installed in horizontal or vertical, upward flow pipelines.

LACIER Piston Check Valves are silent functioning valves that efficiently avert backflow.

The “flapperless” design is mild on the seat as the piston rises and lowers with high and low flow rates.
