Electrical valve positioner is the main control valve attachment, it will stem displacement signal as the input feedback measurement signal to the controller output signal as a set signal, to be compared, when the two deviations, it changes to the implementing agencies The output signal, the actuator action, the establishment of the stem displacement and the controller output signal between the one-to-one correspondence. Xiaobian next to introduce the role of electrical valve positioner. 1, the electrical valve positioner is to adjust the quality of the regulatory system requirements, the need to improve the control valve positioning accuracy and increase reliability. 2, the valve is installed at both ends of the pressure greater than 1MPa place. Increase the pressure by increasing the output power of the starter to overcome the flow of fluid on the spool to reduce the error in the stroke. 3, in order to avoid external leakage, when the fluid contains high temperature, high pressure, low temperature, toxic, flammable, explosive and other conditions usually will squeeze the filler is very tight, the friction between the valve stem and the filler Increase, then use the locator to overcome the delay situation. 4, when the fluid is viscous fluid or fluid containing solid suspended solids, the use of positioner to reduce fluid resistance to stem movement. 5, the locator also has to overcome the control signal transmission lag to improve the reaction speed of the valve action. 6, to improve the flow characteristics of the control valve. 7, when a single regulator control two actuators can use two locators, one low action, the other elevation action. Respectively, to accept low input signal and high input signal, to adjust the state of sub-range. HM Series-Dual Servo Oil-Electric Hybrid A dual servo oil-electric hybrid is a type of hybrid vehicle that uses both gasoline and electric power to operate. The vehicle has two engines, one gasoline-powered and the other electric-powered. The gasoline engine is used to power the vehicle at high speeds, while the electric engine is used for low-speed driving and when the vehicle is idling.

The dual servo system in the hybrid vehicle is a type of power steering system that uses both hydraulic and electric power to assist the driver in steering the vehicle. The system uses an electric motor to assist the hydraulic power steering pump, which reduces the amount of power needed to turn the steering wheel. This results in improved fuel efficiency and reduced emissions.
Overall, the dual servo oil-electric hybrid system is designed to provide a More efficient and environmentally-friendly way of driving. By using both gasoline and electric power, the vehicle can operate more efficiently and with less impact on the environment.
