Questions Valves

  1. Valves are defined as devices to control, or regulate the commencement and -------of air

  2. On resetting valves, for example those equipped with a return spring, the -----position is the
    position assumed by the moving parts of the valve when it is connected but not actuated.

  3. Direct control of a valve means that valve is caused to operate directly by actuating element
    without any -----------elements being operated.

    orifices and _____ valves.

  12. The meter ----flow-control circuit is the preferred method to use for controlling the operating
    speed of cylinders in pneumatic circuits.

State True or False

  1. Restrictor check valves are non return valves which are also employed as flow control valves.

  2. Quick exhaust valves are designed to decrease the position speed in the cylinder
    3 spring force set on a pressure limiting valve or sequence valve corresponding to minimum
    permissible or minimum desired pressure of the controlled fluid.

  3. Ball seat valves ensure perfect sealing at all times in pneumatic circuit

  4. Two way valves are used where a pure straightway function is required, that is when downstream
