High-low circuit High-low circuit — Many systems require a high volume at low pressure for rapid movement of a vise or tool, then low volume at high pressure for clamping or feeding. This can be accomplished by a high-low circuit using two pumps. During rapid traverse, both pumps supply the system.

A volt command anywhere between zero and ten volts results in the equivalent (as a percentage of full scale) pressure output. For example, with a 5 VDC (50%) command, the inlet valve opens to allow pressure downstream. The inlet valve remains open until the internal sensor says, "Hey, I measure 5 VDC (50 psig), you can close now".

Directional air control valves are the building blocks of pneumatic control. Pneumatic circuit symbols representing these valves provide detailed information about the valve they represent. Symbols show the methods of actuation, the number of positions, the flow paths and the number of ports. Here is a brief breakdown of how to read a symbol.

The relief valve will open as pressure caused by a downstream load or backpressure increases high enough to force the poppet or spool open against its spring. A relief valve works by providing an excessively pressurized fluid an open path to tank with the goal of reducing work port pressure.

This permits flow through the outlet to the tank as long as this high pressure level is maintained. Note the external adjusting screw, which varies spring force and, thus, the pressure at which the valve begins to open (cracking pressure) (Fig. 1.3). It should be noted that the poppet must open sufficiently to allow full pump flow.

A ball carrier's 5 points of pressure are fingertips, palms, forearms, biceps, and chest. These 5 points will help ensure the ball is protected from defenders. Fumbles occur when one of the pressure points is typically lacking, resulting in a turnover. This article will show you more about ball security and the 5 points of contact.

The pressure at which a relief valve first opens to allow fluid to flow through is known as cracking pressure. When the valve is bypassing its full rated flow, it is in a state of full-flow pressure. The difference between full-flow and cracking pressure is sometimes known as pressure differential, also known as pressure override.

A three-port valve will be 'line sized' when based on water travelling at recommended velocities (Typically ranging from 1 m/s at DN25 to 2 m/s at DN150). 10 kPa may be regarded as typical pressure drop across a three-port control valve. Aim for valve authority (N) to be between 0.2 and 0.5, the closer to 0.5 the better.

When open- or tandem-center valves are used in circuits requiring pilot pressure to shift the valves, there must be a means of maintaining pressure when the valves are in neutral. One method is to install a backpressure check valve in the tank line. The check valve maintains a backpressure of, say, 50 psi. Download this article in .PDF format

An op-amp is a complex control system that takes the pressure reading from the pressure meter and feeds it back to the power valve so that the pressure is always constant. You can call it a pressure balancing system. If the pressure fluctuates too much, you need to put a capacitor on the line (a pressure holding tank). MrChips Joined Oct 2, 2009
