1. A gate valve comprising:
- (a) a casing having an inlet aperture and an outlet aperture at least one of which has a valve seat,(b) an actuator member reciprocal in said casing transversely of said apertures and having two oppositely disposed faces.(c) means for imparting reciprocation to said actuator member,(d) two plate members flanking said two oppositely disposed faces of said actuator member, at least one of said plate members being a valve head for cooperation with said valve seat, and(e) rectangular rotative means positioned between said actuator member and said two plate members for moving said two plate members from an open to a closed and latched position as said actuator member is reciprocated.

Abstract
A gate valve is disclosed having a casing with inlet and outlet apertures one of which has a valve seat. An actuator reciprocal transversely of the apertures is provided having two oppositely disposed faces. At least one plate member which serves as a valve head flanks at least one of the faces for cooperation with said valve seat. And rectangular-shaped rotative means are positioned between the actuator member and the plate member for moving the plate member from an open to a closed/latched position as the actuator member is moved.
