Question 13

10 out of 10 points

Which of the following is true:

Selected Answers:

Check valves automatically open to allow flow in one direction and seat to prevent flow in the reverse direction.

Ball valves allow quick, quarter turn on-off operation and have poor throttling characteristics.

Gate valves are generally used in systems where low flow resistance for a fully open valve is desired and there is no need to throttle the flow.

Butterfly valves provide significant advantages over other valve designs in weight,space, and cost for large valve applications.

Diaphragm valves and pinch valves are used in systems where it is desirable for the entire operating mechanism to be completely isolated from the fluid.

Plug valves are often used to direct flow between several different ports through use of a single valve.

Globe valves are used in systems where good throttling characteristics and low seat leakage are desired and a relatively high head loss in an open valve isacceptable.

A stop check valve is a combination of a lift check valve and a globe valve and incorporates the characteristics of both.

Safety/relief valves are used to provide automatic overpressurisation protection for a system.
