HIGH/LOW PRESSURE BY PASS VALVE

This valve is used in a 2 parallel-working pumps circuit in order to release the excess of the higher fl ow pump to the tank when this gets the required pressure setting.
Since this moment and on the actuator works with the lower fl ow pumps at higher pressure, consuming less energy.
Connect BP to the higher fl ow pump, AP to the lower fl ow pump, T to the tank, M to the eventual manometer and U as for necessity.
