Straight stroke valve through a linear movement of parts such as the ram to allow or cut off the flow. Straight line program valves are globe valve, gate valve, diaphragm valve, etc. A rotary valve allows or cuts off flow through a rotating part. Rotating parts can rotate 90 degrees of rotary valve called 1 / 4 rotary valve. Sometimes the classification of 1 / 4 rotary valve can be extended to rotary valve with angle less than 270 degrees. It can be seen from the definition that rotary valve is a kind of rotary valve that changes the valve from open position to closed position by rotating parts such as rotary baffle 90 degrees.
