Solenoid , pneumatic and manual valves

Solenoid and pneumatic valves are used in both pneumatic and hydraulic distribution systems, most commonly in seat valve or spool configurations. It is used to control pneumatic cylinders. The valves have different functions such as 5/3, 3/2, 5/2 and can be electrically operated. The most common solenoid valves are two-way, two-position seat valves that simply open and close to allow flow when their coil is energized. However, we offer many more designs, just use the subcategories of our e-shop or read more in the advisory "How to choose the right valve".

Schematic valve markings

each valve position is symbolized by its own square, in which the connection of inlets, outlets and outlets in that position is drawn
(i.e.: if the mark contains 2 squares, it is a 2-position valve, if it contains 3 squares, it is a 3-position valve, etc.)
numbering or lettering of connections is always at the square symbolizing the basic position
arrows connecting the connections indicate the direction of air flow, if the arrows are on both sides, the valve can be used for flow in both directions
the air inlet and outlets are usually placed on the lower side of the square, the outlets from the valves are placed on the upper side of the square
symbols are placed on the side of the square to indicate the method of switching between positions, with the fact that whichever square is drawn becomes active when the signal arrives (as if it had moved to the place of the square of the basic position)

Methods of switching between valve positions
	valve return by spring	lever
	coil, electric control	lever with detent
	pneumatic signal	pedal
	electromagnetic signal	pedal with detent
	boletus	allusion
	mushroom with arrest	pulley
	button	hinged pulley

Examples of valve brands

On this mark we see 2 squares, so it is a two position valve. The marker shows outlets 2 and 4 (top), outlets 3 and 5 and inlet 1 (bottom). There are 5 ways in total, so it is a 5/2 valve. The numerical designation of the connections is at the right square, so this is the basic position of the valve. In this ; position, air from inlet 1 goes to outlet 2, while outlet 4 is connected to exhaust 5. Exhaust 3 is closed. On the left side of the symbol is the pulley control, so it is a mechanically operated valve. When the pulley is actuated, the valve is repositioned according to the left square (adjacent to the pulley symbol). In the second position, inlet 1 is connected to outlet 4 and in turn outlet 2 is connected to vent 3, outlet 5 is now closed. By pressing the pulley, outputs 2 and 4 are therefore switched. There is a spring on the right side of the symbol, which means that the valve returns to the base position independently, using a mechanical spring.

The second example shows a two-position valve again. At the basic position we see the numerical markings 1-inlet, 2-outlet and 3-outlet. So it is a three-way valve (signals 12 and 10 are not included in the paths). In the basic position the inlet is closed and the outlet is connected to the exhaust. Signal 12 (arrow indicates air signal) from the left side moves the valve to the position according to the left square, i.e. the input is connected to output 2 (therefore the signal is marked 12 = 10 + 2). After the signal 12 has disappeared, the valve remains outside the basic position (bistable function) and stays there until the signal 10 comes from the right, which activates the basic position (10 = 10 + 0 i.e. closes the valve). You can still see the miniature button symbols on the sides.
This is a representation of the so-called auxiliary manual control and the valve can be repositioned in an emergency, e.g. with a screwdriver.

Marking of connection threads

On valve labels or schematic markings, you will often find letter or number designations for the individual connection threads. What do these markings mean? They describe whether it is an inlet, outlet, outflow or control connection. In practice, both markings are possible, but the more modern marking is by numbers.

Marking of connection threads
Number	Letter	Importance
1	P	air supply
2, 4, 6 and other even numbers	A, B, C...	outputs from the valve
3, 5, 7 and other odd numbers	R, S, T...	vent chambers of the valve
10 + a number (10, 12, 14...)	X, Y, Z	control signal (in the numeric marking, the second digit denotes the output that is activated by the signal e.g. 14 means that the signal lets air in at output 4, the number 10 indicates that the valve is closed )

Main types of valves:

electromagnetic valves
solenoid valves
pneumatically operated valves
manually operated valves
foot valves

The most important parameters for valve selection:

function
threaded connection
work pressure
working temperature
brightness
flow
power input of the coil

*Today's complex valves are not just about the open and close function. The function diagrams we add to each product photo will help you choose.
