The gate and swing valve has a body which defines at least one valve seat. A closure member inside the valve is pivotably mounted on a support. A cam and cam follower operatively couple the cam to the closure member. A stem has one end coupled to the cam for moving the closure member in a linear motion, in a swinging motion, and then in a linear motion toward the valve seat.
