Valves Objective Questions

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.

4. —————- automatically limit flow to a single direction at the point where they are installed in an air line.

5. In pressure regulating valve inlet pressure is ———-than the outlet pressure.

6. Poppet valves give ——— stroke and few wearing parts give minimum wear

7. The quick exhaust valve is used to exhaust the cylinder air quickly to —————–

8. compared with hydraulic systems, —– varieties of pressure control valves are used in pneumatics

9. As per ISO 1219-1:2006 designation, number 12 or 14 indicate ————– ports

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 Questions on Valves

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
