The hydraulic control valve uses the medium pressure of the pipeline as the power source to open and close and adjust. The front valve and the small pipeline of the system can be combined to have nearly 30 functions, and now it is gradually used. The pilot valve operates by changing the water level and pressure as the control object. Since there are many types of pilot valves, they can be used alone or in combination, so that the main valve can be individually or compoundly adjusted for water level, water pressure and flow rate. Features. However, the main valve is similar to the stop valve. When the valve is fully open, the pressure loss is much larger than that of other valves, and the more the loss coefficient of each opening is close to the full closure, the more the valve is larger and the larger the valve diameter is.
Any hydraulic control valve actuator is a device that uses energy to drive a valve. The hydraulic control valve unit may be a manually operated gear set, a hydraulic control valve to open and close the valve, or a smart electronic component with complex control and measurement devices for continuous valve adjustment. With the development of microelectronics technology, hydraulic control valve actuators have become more complicated. The early actuators were simply motor gearing with position sensing switches. Today's actuators already have more advanced features, and the hydraulic control valve not only opens or closes the valve but also detects the valve and actuator operating conditions to provide a variety of data for predictive maintenance.
The most widely defined definition of an actuator for a hydraulic control valve is a drive that provides linear or rotational motion that utilizes a drive energy source and operates under certain control signals.
The hydraulic control valve actuator uses liquid, gas, electric or other energy sources and converts it into a drive by a motor, cylinder or other device. The basic actuator is used to drive the hydraulic control valve to a fully open or fully closed position.
