Draw symbol of the following DC valve. 1. 2/2 push button type 2. 3/2 solenoid operated 3. 4/2 solenoid operated 4. 5/2 solenoid operated. 5. 5/2 pilot operated valve.

1. 2/2. Valve:

•The 2-port, 2-position (open or close) poppet valve with its symbol is shown in Fig.

               

                      Fig. 2-port, 2-position poppet valve

2. 3/2 Valve:

• A solenoid operated spool valve (3-port and 2 positions) symbol is shown in Fig.

                            

                         Fig. Solenoid operated 3/2 valve

3. 4/2 Valve

•A solenoid operated 4-port, 2 position valve symbol is shown in Fig.

                                       

                                 Fig. Solenoid operated 4/2 valve.

4. 5/2 Valve:

A solenoid operated 5/2 valve is shown in Fig.

                                           

                                                  Fig. 5/2 Valve.

5. 5/2 Pilovt operated DC Valve

• For easy exhausting of the valve 5/2 pilot operated valve are preferred over 4/2 valve:

– 5/2 DC valve spool type design pilot operated.

                           

                                  Fig. 5I2 Pilot operated DC Valve

 

–  No. of parts = 5; no. of position = 2

–  Position depend upon the pilot signal produced

– It is a bistable valve
