Good explanation ❤ But Why required Logic control valve in unloading block .. Any reason?? If we use P to T (4/3 main dcv) and fix PRV then set pressure Is it possible??
Can define cartridge valve&logic valve. Can you define the all pressure control valves.(sequence valve &unloading,loading valve ,pressure reducing valve,pressure relief valve also etc)
Jab only S3 on hoga tab to pressure relief valve me 100 kg/cm2 generate hone ke pahelei logic valve ka drain line open ho jayega. Kiuki uska pressure 0.5 kg/cm2 hain.
S3 operate hone se back pressure generate hoga along with spring pressure...which will make the poppet seat in its position....and drain via relief valve....
