Electro-Pneumatic Systems Fundamentals

What is one of the main advantages of using pneumatic actuators in automated systems?

• They are explosion-proof.

• They are overload safe.

• They are lightweight.

• They are cost-effective.

What does the 'FRL' unit in a pneumatic system stand for?

• Filter, Reducer, Lubricator

• Filter, Regulator, Lubricator

• Filter, Regulator, Leveler

• Filter, Reducer, Leveler

What is the main purpose of a pressure regulator in a pneumatic system?

• To increase air velocity

• To maintain a constant pressure

• To filter out contaminants

• To add oil to the system

How does a dual-pressure valve function in a pneumatic circuit?

• It operates with a single input pressure.

• It operates with alternating input pressures.

• It requires both inputs to be pressurized.

• It functions with no input pressure.

Who is credited with inventing the first air pump capable of producing a partial vacuum?

• Charles Brady
