Rapidrop Figure 301 is a rubber-faced, grooved swing type check valve that allows water flow in one direction only.

A hinged clapper remains open with water flowing in one direction and automatically closes, with the help of an incorporated spring, when flow stops preventing backflow.

Rapidrop Figure 301 grooved swing check valve is suitable for installation in both horizontal and vertical (with the flow upwards) pipelines.
