Directional control valves are one of the most fundamental parts in hydraulic as well and pneumatic machinery. They allow fluid flow into different paths from one or more sources. They usually consist of a spool inside a cylinder which is mechanically or electrically controlled. The movement of the spool restricts or permits the flow, thus it controls the fluid flow.
what doesnt it do?! hmmmmmm

A spring device which maintains the spool of a directional control valve in position.
my directional lights and speedometer do not work could this be control mudule?
the brake control valve is used to control the amount of hydrauic pressure form the hydraulic system to the brake system through the metering valve.
HOW WORK TO PROPORTIONAL valve
The hydraulic three-way directional control valve is designed to operate an actuating unit in one direction. It permits either the load on the actuating unit or a spring to return the unit to its original position.
The 'control pad' is the + shaped directional button.

The idle control valve works by regulating the idle speed of the engine. The idle speed of the engine is usually controlled by the engine of the computer.
The purpose of both the valves is same - that to maintain a certain level(in a vessel or tank...) Simple Level valve could be referred to an ON - OFF valve where as control valve could be referred to an analog type of valve. On - OFF valve is for a crude control of level, while control valve is used where a fine level control is needed.
A directional control(dc) valve is use for selectively connecting the supply passage to the return passage in bypassing relation to the hydraulic motor to interrupt operation of the fan.
