• What is the primary function of an actuator?

• To convert mechanical energy into motion

• • To convert electrical energy into mechanical energy

• • To convert energy into motion

• • To convert thermal energy into mechanical energy

 Pneumatic cylinders are solely used as pneumatic drives.

• True

• False

• What type of cylinder is supplied with compressed air at both ends?

• • Single-acting cylinder

• • Double-acting cylinder

•  Triple-acting cylinder

• • Quadruple-acting cylinder

Pneumatic actuators require valves to control compressed air.

• True

• False

What type of valve controls the path of compressed air?

• • Flow control valve

• •  Relief valve

• Directional control valve

• • Check valve

Solenoid actuated valves use electromagnetic solenoid coils to change the state of a valve from closed to open.

• Trur

• False

• What is the primary function of flow control valves?

• • To regulate the speed of cylinders

• • To control the pressure of compressed air

• •  To regulate the temperature of pneumatic systems

• • To control the direction of air flow

The setting at a one-way flow control valve is effective in both directions.

• True

• False

• What is the purpose of a solenoid in an electro-pneumatic control system?

• • To regulate the pressure of compressed air

• • To control the speed of cylinders

• •  To switch the position of the valve

• •  To generate electrical energy

An electro-pneumatic system comprises two circuits: a pneumatic circuit describing the power section and an electrical circuit describing the signal control section.

• True

• False
