Which component is an electrically controlled valve?

• A. Regulator
• B. Solenoid Valve
• C. PPE
• D. Caliper

Answer: (B)

An electrically controlled valve uses a solenoid to move the valve and change the flow path when an electrical signal is applied. The coil in a solenoid creates a magnetic field that pulls or pushes a valve element (like a plunger or diaphragm), so the valve opens or closes automatically in response to a control signal. This is different from a regulator, which maintains a set pressure without switching states electronically; PPE is protective gear; and a caliper is a measuring instrument. Solenoid valves are designed to be activated by electricity in automation systems, often available as normally open or normally closed and in 2-way or 3-way configurations.
