German Spitzenberger valves Spitzenberger models Spitzenberger prices

With a constant pressure differential across the Spitzenberger valve, the flow rate of a standard valve changes little when the opening varies over a wide range. However, at a certain opening, the flow rate changes sharply, indicating poor regulation performance. A control valve is a valve that adjusts the valve core stroke according to the direction and magnitude of the signal to change the valve's resistance coefficient, thereby achieving flow regulation. Control valves are divided into manual control valves and automatic control valves. Manual and automatic control valves come in many types with different regulation performances. Automatic control valves include self-acting flow control valves and self-acting differential pressure control valves.
