IDIS 403 Ch 9 Questions with Detailed Verified
Answers
A remote-controlled, pilot-operated ___ valve is type of pilot-operated relief valve
that uses one or more external pilot valves to set the pressure at which the relief valve
will open. Ans: relief
A ___ valve is a normally closed pressure control valve that prevents a hydraulic
motor from running away, or speeding out of control. Ans: brake
A ___ pressure control valve is a type of pressure control valve that is remote
controlled and, instead of a spring, uses pilot pressure set at a level specified by a pilot
valve to bias the main spool. Ans: pilot-operated
A ___ valve is a normally closed pressure control valve that stops a vertically mounted
cylinder from running away because of the load weight. Ans: counterbalance
A remote-controlled ___ valve receives a pilot signal from a remote section of a
hydraulic system. Ans: sequence
A ___ valve is a normally closed pressure control valve that can set max systems
pressure and unload the pump, which operates under 100 psi, at the same time. Ans:
unloading
A pilot-operated ___ valve is a type of pilot-operated pressure control valve that is
used to control the max pressure in a hydraulic system. Ans: relief
A ___ valve is a normally closed pressure control valve that makes various operations
occur in an orderly manner, or one after another. Ans: sequence
A remote-controlled ___ valve is a normally closed pressure control valve that uses an
external pilot line to sense pressure form a remote section of the hydraulic system and
counteract the pressure from a hanging cylinder load. Ans: counterbalance
A ___ valve is a normally open pressure control valve that controls pressure in one
leg of a system. Ans: pressure-reducing
