IDIS 403 Ch 6 Questions with Detailed Verified
Answers
In a directional control valve, port __ receives fluid flow from the pump, while port
__ returns fluid flow to the reservoir. Ans: P, T
A __ center position directional control valve allows a hydraulic system to operate
with more than one actuator and with each actuator operating independently of the
others. Ans: closed
A __ is an internal component of a directional control valve that is used to control
fluid flow and to connect internal passages and ports. Ans: spool
There are __ different subplate designs Ans: seven
A __ center position directional control valve is used to hold the piston in a cylinder in
the desired position while allowing fluid flow to be directed back to the reservoir
without the need to activate a relief valve. Ans: tandem
__ mounting is a method that uses tubing or threaded pipes that connect directly to a
directional control valve. Ans: In-line
A directional control valve __ is a mechanism that is used to move the position of the
spool in a directional control valve. Ans: actuator
Solenoids alone are not strong enough to move a directional control valve spool when
the fluid flow is greater than __ gpm Ans: 25
In a directional control valve schematic symbol __ the position boxes depict the
direction of fluid flow for each spool position. Ans: internal arrows inside
A hydraulic system that does not have a variable displacement, pressure compensated
pump typically uses a __ centered or __ center position directional control valve so
that the hydraulic fluid can be returned to the reservoir Ans: Open, tandem
