German SKF Sealing valve SKF Sealing model SKF Sealing price

SKF Sealing valve: When the pressure difference across the valve is constant, the flow rate of a standard valve changes little as the opening varies over a wide range. However, at a certain opening, the flow rate changes sharply, indicating poor regulation performance. A control valve 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 and automatic types. Manual and automatic control valves come in various types with different regulation performances. Automatic control valves include self-operated flow control valves and self-operated differential pressure control valves.
