The movement process of Lianggong valve can be controlled by stroke, torque, or axial thrust. Due to the working characteristics and utilization rate of the actuator depending on the type of valve on the pipeline or equipment, the working specifications and position of the equipment. Therefore, it is crucial to master the correct selection of the actuator, taking into account the prevention of overload (working torque higher than control torque). The operating torque is the main parameter for selecting actuators. The output torque of electrical equipment should be 1.2~1.5 times the operating torque of Lianggong valve. There are two main structures for actuators: one is without a thrust plate, which directly outputs torque; Another option is to configure thrust plates. At this point, the output torque is converted into output thrust through the valve stem nut in the thrust plate.

執行器輸出軸旋轉圈數與良工閥門閥門的公稱直徑、閥桿螺距、螺紋頭數有關，按M計算。=H/ZS計算(公式中：M為電動設備應滿足的總旋轉圈數；H為良工閥門閥門的開啟高度，mm；S是閥桿傳動螺

The number of rotations of the actuator output shaft is related to the nominal diameter, stem pitch, and number of thread heads of the Lianggong valve, and is calculated according to M= H/ZS calculation (in the formula: M is the total number of rotations that electric equipment should meet; H is the opening height of Lianggong valve, mm; S is the valve stem transmission screw)

紋的螺距，mm；Z為閥桿螺紋頭數。)對于多旋轉的明桿良工閥門閥門，如果執行器允許通過的大閥桿直徑不能通過所配良工閥門閥門的閥桿，則不能組裝成電動良工閥門閥門。因此，電氣設備中空輸出軸的內徑必須大于明桿良工閥門閥門的閥桿外徑。良工閥門閥門的啟閉速度快，容易產生水擊現象。所以，應根據使用條件的不同，選擇合適的啟閉速度。安裝、連接方式：良工閥門閥門的安裝方式包括垂直安裝、水平安裝、落地安裝。

Thread pitch of the pattern, mm; Z is the number of valve stem threads For multi rotating rising stem valves, if the large stem diameter allowed by the actuator cannot pass through the valve stem of the equipped valve, it cannot be assembled into an electric valve. Therefore, the inner diameter of the hollow output shaft of electrical equipment must be greater than the outer diameter of the stem of the rising stem valve. The opening and closing speed of Lianggong valve is fast, which is prone to water hammer phenomenon. Therefore, the appropriate opening and closing speed should be selected based on different usage conditions. Installation and connection methods: The installation methods of Lianggong valve include vertical installation, horizontal installation, and floor installation.
