Piston valves | Choosing the right valve
Globe valves and piston valves operate on the same principle. A rod, with a saucer-shaped part or piston at the end, descends into the valve to block the flow of fluid. These valves are particularly suitable for regulating a fluid according to the pressure in the pipe. Many globe valve actuators contain a setting spring that allows the valve opening to be adjusted according to pressure. The main disadvantage of this type of valve is the significant head loss....
