It consists of a lead free brass body with two independently operating rubber and stainless steel check valves, with an atmospheric vent located between the them. It is in-line field testable, non-removable and designed for non-continuous pressure applications. It is ideal for installation in service sinks, chemical dispensers, sill cocks, and frost proof hydrants. Maximum working pressure is 125 psi (10.6 bar).
