A simple hydraulic schematic showing apparatus for testing the strength of a hydraulic hose splice.
Water enters through normally closed solenoid valve (1) and passes through intake flow meter (2) to high pressure pump (4). Intake water pressure is monitored by pressure gauge (3). The hose to be tested connects between pump (4) and normally open solenoid activated drain valve (7). To test the hose, pump drive motor (5) is turned on, the solenoid of drain valve (7) is activated, closing the valve, and the pump is run to pressurize the hose. Test pressure is monitored by gauge (6). When the test is complete or the hose fails, the solenoid of drain valve (7) is deactivated, opening valve and discharging water, depressurizing the system. All components are operated electrically by a remote control circuit so that the operator may perform the test from a protected location, monitoring it with a camera and video monitor.

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]

"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. ...
The spool (sliding type) consists of lands and grooves.The lands block oil flow through the valve body. The grooves allow oil or gas to flow around the spool and through the valve body. There are two fundamental positions of directional control valve namely normal position where valve returns on removal of actuating force and other is working position which is position of a valve when actuating force is applied. There is another class of valves with 3 or more position that can be spring centered with 2 working position and a normal position. ...
Directional control valves can be classified according to:
(1) number of ports;
(2) number of positions;
(3) actuating methods;
(4) type of spool." [Directional control valve. Wikipedia]

The vector stencils library "Valves" contains 91 symbols of piping and plumbing valves.
"A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically valves fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure.
The simplest, and very ancient, valve is simply a freely hinged flap which drops to obstruct fluid (gas or liquid) flow in one direction, but is pushed open by flow in the opposite direction. This is called a check valve, as it prevents or "checks" the flow in one direction.
People in developed nations use valves in their daily lives, including plumbing valves, such as taps for tap water, gas control valves on cookers, small valves fitted to washing machines and dishwashers, safety devices fitted to hot water systems..." [Valve. Wikipedia]
Use the design elements library "Valves" to draw building plans, schematic diagrams, blueprints, or technical drawings of industrial piping systems; process, vacuum, and fluids piping; hydraulics piping; air and gas piping; materials distribution; and liquid transfer systems using the ConceptDraw PRO diagramming and vector drawing software.
