Difference Between Solenoid Valve and Motorized Valve
1. How it works An electromechanical solenoid valve is controlled by an electrical current. Motorized valves are operated by an electric signal from the motor, which opens, closes, or stops the valve. 2. Types of valve 2.1 Solenoid Valve An inlet and outlet are connected to the pipeline by a two-way solenoid valve . There are two types of switching functions: Normally Open (when power is on, the solenoid valve is closed, cutting off the fluid), Normally Closed (when power is off, the solenoid valve is open, allowing the fluid to pass). A three-way solenoid valve has three ports and two holes connected to the pipeline. Controls can be categorized as Normally Closed, Normally Open, or General Type. Double-acting cylinders are generally operated by four-way solenoid valves. One pressure port, two cylinder ports, and one or two exhaust (oil) ports connect the pipelines. 2.2 Motorized Valve Motorized quarter-turn valves are designed to automate the precise operation of valves that open a
