A Caterpillar 930G fitted with a loader rake on a residential construction site in South Florida. The Caterpillar 930G is a hydraulic front end loader manufactured by Caterpillar Inc. The 930G, with 149 hp (111 kW) of net flywheel power at 2300 rpm , [ 1 ] it is classified as a small wheeled loader in the line of Caterpillar's excavators.
The valve is often described as a needle valve, although this is a misnomer. A true needle valve uses a tapered needle in a tapered seat, so as to provide fine control over flow rate. The float valve uses a pointed needle against a square-edged seat, to give a positive shut-off. As the float relies on gravity, the chamber must be mounted ...
John Deere Front end loaders CAD model tracing of a tractor mounted loader mechanism CAD model tracing of a skid loader mechanism. A loader is a heavy equipment machine used in construction to move or load materials such as soil, rock, sand, demolition debris, etc. into or onto another type of machinery (such as a dump truck, conveyor belt, feed-hopper, or railroad car).
The most common final control element in the process control industries is the control valve. The control valve manipulates a flowing fluid, such as gas, steam, water, or chemical compounds, to compensate for the load disturbance and keep the regulated process variable as close as possible to the desired set point.

A bulldozer or dozer (also called a crawler) is a large, motorized machine equipped with a metal blade to the front for pushing material: soil, sand, snow, rubble, or rock during construction work. It travels most commonly on continuous tracks , though specialized models riding on large off-road tires are also produced.
Simple hydraulic control valves are binary, they are either on or off. Servo valves are different in that they can continuously vary the flow they supply from zero up to their rated maximum flow, or until the output pressure reaches the supplied pressure. More complex servo valves can control other parameters.
Typically, this separate valve controls a high pressure or high flow feed. Pilot valves are useful because they allow a small and easily operated feed to control a much higher pressure or higher flow feed, which would otherwise require a much larger force to operate; indeed, this is even useful when a solenoid is used to operate the valve.
