Abstract

The non-return valve may be used to prevent pressure drop back flow in domestic water services. It incorporates an axially slidable closure sprung (31) valve-plug (2) of a truncated egg shape and located by a housing (1). Plug sliding is guided by perimeter rails (19) and hub engaging plug barrel grooves and entering a blind plug bore (30) respectively. Hub is located downstream of the plug connected to rails (19) by a cruciform frame (23) and forming a demountable guidage cage. The bore may act with a blind plug bore to contain a spring (31), and a ring frame (18) may connect leading rail (19) ends. The plug may have a concave nose (26), using a ring seal (28) which contacts a conical body face (12) to effect closure.
