This video explains the working
This video explains the working of punch press circuit using unloading valve. This hydraulic circuit is also known as High-low double pump system used in punch press application.
It uses unloading valve, 4/3 manually operated, spring controlled D.C. valve & two pumps P1 & P2. Pump P1 is constant low volume, high pressure pump whereas pump P2 is variable high volume, low pressure pump.
Due to back pressure generated in the circuit, the unloading of the pump P2 takes place through unloading valve. You may find various interesting hydraulic & pneumatic circuit working in our playlist.
