CHECK VALVES AND CLIPS THEREOF

摘要

A check valve comprises a valve body (2) having valve seats (10) therein. A hinge pin (18) extends across the body. A pair of plates (14, 16) having hinge lugs (56,58) are rotatably mounted on the hinge pin (18) via the hinge lugs to allow rotation of the plates from closed positions in which the valve faces engage respective valve seats to open positions in which the valve faces are spaced from the respective valve seats.
