Electric Control Valve

Electric Control Valve The electric control valve is a core actuating component in industrial automation process control, designed to precisely regulate the flow, pressure, temperature, or level of pipeline media. Its core function lies in receiving standard control signals (e.g., 4–20 mA) from automation systems (such as DCS or PLC) and driving the valve opening to achieve continuous and accurate positioning, thereby enabling closed-loop control of process parameters. An electric control valve typically consists of two main components: the control valve body (including the valve plug, valve seat, bonnet, stem, etc.) and the electric actuator. The valve body features various structural designs, such as single-seat globe, double-seat globe, sleeve, and angle types, to meet different flow characteristics and differential pressure requirements. Electric control valves produced by Kaiweixi Valve Group offer core advantages such as high control precision, fast response speed, long-distance signal transmission, and seamless integration with digital communication systems. Their control characteristics (e.g., linear or equal percentage) can be tailored to specific process requirements to achieve optimal control performance. Electric control valves are widely used in applications demanding precise, stable, and remote automatic control, making them essential in process industries such as petroleum and chemical processing, power generation, pharmaceuticals, HVAC (heating, ventilation, and air conditioning), and fine chemical manufacturing.

ZAZN electric straight-through double-seated regulating valve is an industrial automation control valve composed of a linear electric actuator and a straight-through double-seated balanced valve body. By receiving standard analog signals (4-20mA DC or 0-10V DC) from control systems such as PLC or DCS, the valve accurately converts electrical energy into axial thrust. This thrust drives the valve stem, moving the upper and lower valve plugs relative to the seats. Due to the double-plug structure, the forces acting on the upper and lower plugs from the medium are opposite in direction and similar in magnitude, allowing most of the unbalanced force to be offset. Consequently, this valve features a large allowable pressure differential, high flow capacity, and excellent vibration resistance, making it particularly suitable for industrial process control systems with high flow rates, high pressure drops, and relatively relaxed leakage requirements.Product Image of ZAZN Electric Straight-through Double-seated Regulating Valve
