What Is The Difference Between Solenoid Valve And Motorized Valve? Motorized valves and solenoid valves are commonly used in industrial control systems to adjust the direction of the media, flow, speed and other parameters. Solenoid valve and motorized valve in the performance and use are different, we will introduce from the following 3 points to you what is the difference between solenoid valve and motorized valve. 1. Differences In Working Principles Solenoid valve uses electromagnetic coils magnetic field to pull the spool, thereby opening-closing the valve body, coil power, spool depends on the spring back pressure back. Motorized Valve uses electric actuator control to achieve the valve opening and closing. It can be divided into two parts, the upper part of the electric actuator, the lower part of the valve. The driving device of the motorized valve is a reversible electric motor, which drives the valve core to control the valve through the rotation of the motor for a certain period of time Motorized Valve is divided into two kinds, one is Quarter Turn motorized valve: to achieve 90 degrees internal rotation for Rotary Valves. The other is a Linear motorized valve: Electric actuator with Linear Valve. The motorized Valve is usually connected by the electric actuator and the valve, after installation and debugging, it becomes the motorized valve. The motorized valve uses the electric energy as the power to connect the electric actuator to drive the valve and realize the valve switching and regulating action. 2. Differences In Applications Solenoid valve can only be used as the switch volume and can only be used for small pipe control, common in DN50 and below the pipeline. Solenoid valve has excellent leak-proof performance, quick open & close operateion, low power consumption, suitable for some corrosion other chemicals in the pipeline as cut-off application. Electric Valve has AI feedback signal, often used in large pipelines. Most of them are used to regulate the flow of the pipeline, which are normally installed at the outlet of the air supply and refrigeration pipeline, and can also be used in the liquid pipeline. 3. Differences In The Nature Of Work Solenoid valve general flow coefficient is very small, and the working pressure is very small. For example, the general 25 mm diameter solenoid valve flow coefficient than 15 mm diameter motorized ball valve much smaller. Solenoid valve is driven through the electromagnetic coil, more easily damaged by voltage shocks. Equivalent to the role of the switch. Solenoid valve switch speed is extremely fast. Motorized Valve is driven by motor. Motorized Valve opening angle can be adjusted, open or closed to complete the action takes a certain amount of analog time. Solenoid valves can either be Normally Open / Normally Close, where as for motorized valve to achieve such a function requires a reset device.
