"Directional control valves are one of the most fundamental parts in hydraulic machinery 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. ...
While working with layouts of hydraulic machinery it is cumbersome to draw actual picture of every valve and other components.instead of pictures symbols are used for variety of components in the hydraulic system to highlight the functional aspects. symbol for directional control valve is made of number of square boxes adjacent to each other depending on the number of positions.connections to the valve are shown on these squares by capital letters.usually they are named only in their normal position and not repeated in other positions.actuation system of the valve is also designated in its symbol."

How to Create a Mechanical Diagram

mechanical-diagram-example
Mechanical Engineering drawing is a type of technical drawing that helps analyze complex engineering systems. Mechanical Engineering diagrams are often a set of detailed drawings used for engineering or construction projects. Making Mechanical Engineering diagram involves many different elements that can be managed using ConceptDraw PRO. You can design elements for drawing parts, assembly, pneumatic, and hydraulic systems for mechanical engineering. With ConceptDraw PRO you can easily create and communicate the Mechanical Engineering diagram of any complexity.
The vector stencils library "Valve assembly" contains 141 symbols of pressure and flow regulators, flow direction indicators, controls, and symbols to design flow paths of control valves.
Use these valve assembly shapes to design the engineering drawings of hydraulic and pneumatic valve assemblies in fluid power systems.
"Control valves are valves used to control conditions such as flow, pressure, temperature, and liquid level by fully or partially opening or closing in response to signals received from controllers that compare a "setpoint" to a "process variable" whose value is provided by sensors that monitor changes in such conditions.
The opening or closing of control valves is usually done automatically by electrical, hydraulic or pneumatic actuators. Positioners are used to control the opening or closing of the actuator based on electric, or pneumatic signals.
A control valve consists of three main parts in which each part exist in several types and designs: Valve's actuator, Valve's positioner, Valve's body.

The vector stencils library "Fluid power equipment" contains 113 symbols of hydraulic and pneumatic equipment including pumps, motors, air compressors, cylinders, meters, gauges, and actuators. Use it to design fluid power and hydraulic control systems.
"Fluid power is the use of fluids under pressure to generate, control, and transmit power. Fluid power is subdivided into hydraulics using a liquid such as mineral oil or water, and pneumatics using a gas such as air or other gases. Compressed-air and water-pressure systems were once used to transmit power from a central source to industrial users over extended geographic areas; fluid power systems today are usually within a single building or mobile machine."

The vector stencils libraries "Pipes 1" and "Pipes 2" contain 28 and 48 pipe, tubing and fitting symbols, respectively.
"Pipe is hollow cylinder used to conduct or transfer fluids (liquids and gases) from one place to other place. The main difference between pipe and tube is the critical dimension used to describe the pipe size or the tube size. For pipe, internal diameter (ID) roughly corresponds to the nominal pipe size for standard wall thickness. For tube, the outer diameter (OD) closely corresponds to the tube size. In current European standards pipes and tubes are nowadays described as outside diameter by wall thickness. The three standard types of pipe ends used in the piping industriesare; Plain Ends (PE), Threaded Ends (TE) and Beveled Ends (BE). In the past, many types of material have been used in conveying water from one point to another. Masonry and wood were probably the first materials used. Plastics are the newest, and are now being used quite extensively." [Piping. Wikipedia]

Retract resistor check valve application: pneumatic cylinder, piston driven by Compressed air through 2 Retract resistor check valves.
"A check valve, clack valve, non-return valve or one-way valve is a valve that normally allows fluid (liquid or gas) to flow through it in only one direction.
Check valves are two-port valves, meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave. There are various types of check valves used in a wide variety of applications. Check valves are often part of common household items. Although they are available in a wide range of sizes and costs, check valves generally are very small, simple, or inexpensive. Check valves work automatically and most are not controlled by a person or any external control; accordingly, most do not have any valve handle or stem. The bodies (external shells) of most check valves are made of plastic or metal.
An important concept in check valves is the cracking pressure which is the minimum upstream pressure at which the valve will operate. Typically the check valve is designed for and can therefore be specified for a specific cracking pressure.
Heart valves are essentially inlet and outlet check valves for the heart ventricles, since the ventricles act as pumps." [Check valve. Wikipedia]
