Piston Valve is the device for controlling the fluid motion along with the tube or pipe with the help of the linear motion of the piston within the chamber or cylinder itself. It has the mechanical way of continuous adjustment of the upstroke and downstroke of various valves which in turns provide improved playing response. Piston valves are considered as one of the most powerful available in spudgunning having the ability to dump several litres of pressurised air in a few thousandths of second. Earlier piston valves were being used by Curtis Lo in his stationary steam engines and also in other engines after this. Cylindrical piston valves are used for changing the pitch during the playing of many brass instruments.
