The solenoid valve coil is widely used in chemical production, generally it is used to perform installation of pneumatic gas path mechanism, through the control of pneumatic on-off valve to control the switch. Xiao Bian today as we introduce the electromagnetic valve symbol in detail.
A solenoid valve, symbols
     From top to bottom from left to right are

     Direct drive type: two two, two three general, two three general fault.

     Pilot: two two, two three general, two three general fault.

     Two five single control, two position five way double electric control.

     Three five three five in the letter, in three through five release, mv.

Two, solenoid valve symbol Xiangjie

     Solenoid valve solenoid valve function symbol refers to the description ofthe schematic, generally used in pneumatic system planning and product identification, the pneumatic system planner and solenoid valve usersunderstand the product function.

     In the planning process, often need to see gas path. All kinds of solenoid valve as the embodiment of the respective pneumatic symbol appears in the drawings, this method is marked, the electromagnetic valve symbol.

The general meaning of the symbols are as follows:
 

(1) the working range indicate valve box, there are several boxes marked"a few";

(2) in the box is on the arrow marked oil, but does not necessarilyindicate the direction of the arrow direction flow practice;

(3) the box symbol "" or "" indicates that the channel is illogical;

(4) there are several interface number box outer joins, it marked a few "";

(5) in general, valve and oil supply system or gas path connecting theinlet / inlet valve and marked with the letter P; the system back to the oil /gas path connected with air / oil return back to t (sometimes o) marked;valve and connecting components and performance of oil / gas with a, Bmarked. Sometimes in the graphic symbols with L indicating the leakage oil port;

(6) the valve has two or more than two working range, during a normalposition, the spool is being operated force location range. Graphic symbols in a three position valve normal position. The two is to use the valve spring reset spring box near the pathway to its normal position.Manufacturing system diagram, the oil / gas path should be connected to the valve to the normal position.

The solenoid valve series code: ZC

1, explosion proof for "F" is not the proof does not indicate

2, do not indicate the normally closed normally open; "K"; "Z self stick with"

3, directly driven by "0"; direct action step with "3"; "5" pilot "Q; fast urgentinterception"

4, internal thread with "1"; "2"; external threads with flanges for "8"; "6"welding; apply "9 card"

7, cast steel with "C" stainless steel "B" with "P" with PTFE plastic "S"

8, with the signal using the "X" manual "S" with "D check"

Two position three way solenoid valve marked:

A: ZCF3/3+ should be marked and other code explosion

One into two: ZCF3/31+ should be marked and other code explosion

Two A: ZCF3/32+ should be marked and other code explosion
Special tips:

1, the solenoid valve coil to the level of the equipment, the best, for the vertical equipment, when ordering instructions

2, there are impurities in the medium, please 30 ~ 100 mesh filterequipment / inch

3, such as the solenoid valve outlet pressure is greater than the inlet pressure, the valve will reverse guide, now should check valve in theexport of equipment

The solenoid valve 4 series products, the company can plan specifically for your special needs
