1. valve with multiple inlets and/or outlets in specialized piping systems to
divert flow direction, allowing fluid sources to be switched. - ANSWER ✓
multiport valve
2. a type of globe valve that has a needle-shaped element that fits snugly into
the seat. - ANSWER ✓ needle valve
3. a type of valve mechanism that has a collar that keeps the stem from moving
up and down. You cannot tell if this type of valve is open or closed by
looking at it. - ANSWER ✓ nonrising stem
4. a specially designed material used to stop fluid from entering or escaping;
packed around the shaft (stem) of a valve, or shaft of a pump. - ANSWER
✓ packing (number 10)
5. a mechanical device that contains and compresses packing. - ANSWER ✓
packing gland
6. device that uses an airtight cylinder and piston to move or position the stem;
it is commonly used with automated gate valves or slide valves. - ANSWER
✓ Piston actuator
7. a valve that has a plug-shaped element; used for on/off service. - ANSWER
✓ plug valve
8. valve set to automatically relieve pressure in a closed system at a
predetermined set point for liquids. - ANSWER ✓ relief valve
, 9. a type of valve mechanism in which the stem of the valve rises along with
the gate, disk, or globe when opened. You can tell if this type of valve is
open or closed by looking at it. - ANSWER ✓ rising stem
10.valve set to automatically relieve pressure in a closed system at a
predetermined set point for gases. - ANSWER ✓ safety valve
11.a device that keeps track of the measured condition (e.g., temperature,
pressure) and its fluctuations so that when sufficient variation occurs it will
originate the signal to change the operation of the system. - ANSWER ✓
sensing device
12.the section of a valve that contains packing. - ANSWER ✓ stuffing box
13.a valve with three ports (one inlet and two outlets) used to divert flow
direction. - ANSWER ✓ three way valve
14.reducing or regulating flow below the maximum output of a valve. -
ANSWER ✓ throttling
15.a device that converts variations in a physical quantity, such as pressure or
temperature, into an electrical signal, or vice versa. - ANSWER ✓
transducer
16.an electronic device used to generate and send electromagnetic waves
carrying messages or signals. - ANSWER ✓ transmitter
17.the flow-control element and seats in a valve. - ANSWER ✓ trim
18.a fluid flow in which the velocity at a given point varies erratically in
magnitude and direction. In valves, can cause metal erosion, seat damage,
and damage to the flow controlling element. - ANSWER ✓ turbulent flow
19.a device used to stop, start, restrict (throttle), or direct the flow of fluids -
ANSWER ✓ valve
20.the outer casing of most or all of the valve that contains the internal parts or
trim. - ANSWER ✓ valve body
