The primary purpose of a valve is to direct and control the flow of fluids by starting,
stopping, and throttling (restricting) flow to make processing possible.
t/f - ansTRUE
The most common way to classify valves is by the valve's flow control element design (e.g.,
gate, ball).
t/f - ansTRUE
Valves that are used for isolation are classified as block valves.
t/f - ansTRUE
Gate valves are the most common valve used for isolation.
t/f - ansTRUE
Gate valves are sized to fit the outside diameter of a pipe and a lot of restriction occurs when
it is in the open position.
t/f - ansfalse. Gate valves are sized to fit the inside diameter of a pipe and very little
restriction occurs when it is in the open position.
Gate valves typically are operated in the "wide open" or "completely shut" position.
t/f - ansTRUE
Gate valves are used only when flow rates are restricted.
t/f - ansfalse not restricted

t/f - ansTRUE
t/f
The seats in a gate valve fall into two categories: replaceable and fixed. - ansTRUE

t/f - ansTRUE
System pressure helps position the gate in its seat. The higher the pressure, the more tightly
the disc fits into the seat.
t/f - ansTRUE
Stainless steel gate valves are used in corrosive, high- and low temperature service.
t/f - ansTRUE
Bronze gate valves and brass gate valves are used in high temperature, high-pressure service.

Like the gate and globe valves, a ball valve will lift the flow-control device out of the process
stream.
t/f - ansFALSE.
Unlike the gate and globe valves, a ball valve will not lift the flow-control device out of the
process stream.

t/f - ansfalse
The ball check is as durable as a lift check and more durable than a swing check
Butterfly valves are used for throttling however, it should be noted that they have non
uniform flow characteristics.
t/f - ansTRUE

turn on the valve handle.
t/f - ansTRUE
Diaphragm valves typically are used in low-pressure applications and require packing
t/f - ansFALSE
