Description

The DC-500 double check valve is designed to provide the best protection and durability against back flow caused by negative or opposite pressure. Back flow may cause infiltration of chemicals, fertilizers and/or other pollutants into drinking water systems. The DC-500 is reliable and easily maintained, and does not require special tools. The DC-500 has two independent, easily replaceable, spring check valves in capsules. The DC-500 is recommended where the degree of pollution doesn't impose the use of an RP-500.
