When the increase in oil pressure in the pulse unit overcomes the tension of Relief Valve Spring,
the oil in the high-pressure chamber displaces the Relief Valve Ball and travels to the Piston via bypass.
The Piston displaced by oil moves the Operating Rod, which causes the Shut-off Valve Ball to be displaced via Pilot Valve.
Immediately after the Pilot Valve opens, the Shut-off Valve gets closed and the tool shuts off.
