Multi-marker sphere - Ethylpropyl seat - 304 side-mounted plate - 420 shaft - Electric head

Detailed introduction:

This valve uses an electric actuator to control its opening and closing. An electric actuator is a type of drive device that delivers either linear or rotary motion, operating by utilizing a specific source of power and responding to a control signal. The actuator converts energy—whether hydraulic, pneumatic, electrical, or from other sources—into mechanical motion through mechanisms such as motors, cylinders, or other devices. There are three basic types of actuators: part-turn, multi-turn, and linear, each suited for different applications. The primary function of these basic actuators is to move the valve fully open or fully closed, precisely positioning it at any desired point in between. While most actuators are still primarily used for switching valves on and off, modern actuator designs have evolved far beyond simple on/off functionality. Today’s actuators incorporate advanced features such as position sensors, torque detectors, electrode protection systems, logic control units, digital communication modules, and even PID control modules—all integrated into a compact, space-saving housing. As more and more factories adopt automated control systems, replacing manual operations with mechanical or robotic equipment, there’s an increasing demand for actuators that serve as the critical interface between the control system and the valve’s mechanical movement. Moreover, operators now expect actuators to significantly enhance both operational safety and environmental protection. In particularly hazardous environments, automated actuator systems can minimize the risk of injury to personnel by reducing human exposure to dangerous conditions. For certain specialized valves, emergency opening or closing capabilities are essential to prevent further escalation of risks while simultaneously minimizing damage to the facility. Meanwhile, for high-pressure, large-diameter valves, the required actuator output torque can be exceptionally high. In such cases, actuators must not only deliver robust mechanical performance but also maintain optimal efficiency, often achieved through the use of high-output motors capable of smoothly handling these massive valves. On the other hand, for smaller valves requiring lower torque, compact, lightweight electric actuators have emerged, offering advantages like reduced weight, a more streamlined design, and enhanced versatility—all without compromising on functionality.
