Electromagnetic pneumatic distributors 5/2 A4 series
Electromagnetic pneumatic distributors 5/2 A4 series, have a 1/2 connecting thread.
Five-way valves are typically used to control double-sided cylinders.

Due to the fact that the pace of automation of production is growing every day, the need to replace physical labor with the work of "ordinary" pneumatic mechanisms (pneumatic drives, pneumatic cylinders) is also growing. Not one pneumatic drive or the pneumatic cylinder will not be able to fully work if it is not controlled, and so, the pneumatic distributor controls the operation of the drive.
Pneumatic valves PNEVMOLUX are divided into three types:
1. 2/2 - two linear (two openings for air, input and output), two-position (two switching positions).
2. 3/2 - three linear (three openings for air, inlet, outlet and air discharge), two-position (two switching positions)
3. 5/2 - five linear (five openings for air, inlet, two outlets and two air vents), two-position (two switching positions)
4. 5/3 - five linear (five openings for air, inlet, two outlets and two air vents), three-position (three switching positions)
Each type of electro-pneumatic distributor differs in the type of control:
Electropneumatic - the spool of the distributor moves by means of an open air channel using an electromagnet.
Pneumatic - the spool of the distributor moves with the help of the supplied compressed air into the channel allocated for this.
Mechanical - the spool of the distributor is moved using the handle or the pedal.
The electro-pneumatic distributor is controlled by an electromagnetic coil, we have a large list of varieties of coils for various voltages such as: 12 V, 24 V - DC and 24 V, 110 V, 220 V, 380 V - Alternating current (50-60 Hz.)
One of the most important advantages of these pneumatic valves is its weight (400 grams) and its small dimensions, which makes it possible to place it both on the pneumatic cylinder body and on the equipment itself.
As for the installation of pneumatic valves of the A4 model, they have two holes on their body located on different planes, this allows you to mount the valve in any convenient place. If the pneumatic circuit of the equipment involves the installation of a large number of pneumatic valves, then we offer mounting plates. The licensed pneumatic plate allows you to place from one to six A4 series electro-pneumatic valves. A huge plus of pneumatic plates is space saving, fewer quick couplings, money saving.
The durability of the distributor is usually determined by the state of the compressed air produced by the compressor (for compressed air, see our article “What is clean air”), therefore it is recommended to use filter driers and oil sprayers in the overhead line, you can choose this product in the section “Preparing compressed air” air ", but if all the same the cuffs installed on the spool of the pneumatic distributor are worn out, then you can always get a repair kit from us.
A repair kit implies a set of spool o-rings; this is usually the only part that has wear in these valves. Removing and installing the dispenser cuffs themselves does not require a huge skill and a highly skilled specialist. As a result, we get a full-fledged distributor for a low cost and extend its life for a long time.
All the presented models of electro-pneumatic valves are in stock, stocks of valves are constantly replenished and can be purchased without difficulty.
