What is the function of directional control valves?

• they are used to control flow rate

• they are used to regulate pressure in the system

• They are used to influence the direction of flow of air stream

• they allow flow only in one direction

What is the description of 5/2 single pilot valve?

• This valve is used for automatic operation, and you can control the valve by a pneumatic signal and a spring return

• The valve can be controlled by two pneumatic signals. This valve keeps the last position active after removing the applied signal

• This valve is used for manual operation,

  and you can control the valve by the

  selector switch

• When the push button is actuated the valve is closed, thus stopping the air to flow

What is the description of 5/2 double pilot valve?

• This valve is used for automatic operation, and you can control the valve by a pneumatic signal and a spring return

• The valve can be controlled by two pneumatic signals. This valve keeps the last position active after removing the applied signal

• This valve is used for manual operation,

  and you can control the valve by the

  selector switch

• When the push button is actuated the valve is closed, thus stopping the air to flow

What is the difference between N/O and N/C valves?

• For the N/O valve Supply port will be blocked in the un-actuated (Initial) position, and vice versa for the N/C valve

• For the N/C valve Supply port will be blocked in the un-actuated (Initial) position, and vice versa for the N/O valve

• The N/C valve has 3 ports and 2 positions, and the N/O valve has 5 ports and 2 positions

• There is no difference between the two valves

What is the function of single acting cylinder?

• Are a device that will give rotational motion when supplied by air

• Used to Control the Air supply to the system and increase efficiency

• Used to convert the

  pressure energy to mechanical energy (linear force in two directions)

• Used to convert the

  pressure energy to mechanical energy (linear force in one direction only)

What is the function of double acting cylinder?
