CVW-40
Steam

The check valve, also known as a one-way or non-return valve, is designed to prevent medium backflow in pipelines. It allows fluid to flow in only one direction, enhancing safety in single-direction flow systems. The CVW-40 Series wafer lift check valve is suitable for hot water, condensate, oil, and other fluids.
Available in various connection diameters, it accommodates different medium flow requirements. Its integrated cam design simplifies installation—by rotating the valve body so the cam contacts the flange bolts, the valve is precisely centered in the pipeline.
