摘要
A valve apparatus and pneumatically driven diaphragm pump incorporating same having a valve body having a longitudinal axis and an actuator having an axis with a first end and a second end. The first and second ends have first and second diaphragms, respectively, disposed thereon and located transversely to the axis of the actuator. Upon inserting the actuator into the valve body, the first and second diaphragms define wall portions of first and second chambers at the first and second ends of the axis of the actuator, respectively, and a chamber defined between the diaphragms.
