Two pumps "HI-LOW" Unloading valves
Unloading valve "High-Low"
This valve is used in a 2 parallel-working pumps circuit in order to release the excess of the higher flow pump to the tank when this gets the required pressure setting. Since this moment and on the actuator works with the lower flow pumps at higher pressure, consuming less energy..
Sizes:
- G 3/8"
- G 1/2"
- G 3/4"
Pressure:
- low 20-80 bar
- high 50 - 300 bar
- Hydraulic scheme
Connect BP to the higher flow pump, AP to the lower flow pump, T to the tank, M to the eventual manometer and U as for necessity.
Unloading valve "High-Low" flangeable
This valve is used in a 2 parallel-working pumps circuit in order to release the excess of the higher flow pump to the tank when this gets the required pressure setting. Since this moment and on the actuator works with the lower flow pumps at higher pressure, consuming less energy. It's ideal for direct flange-mounting on solenoid valves.
Sizes:
- G 3/8"
- G 1/2"
- G 3/4"
Pressure:
- low 20-80 bar
- high 50 - 300 bar
- Hydraulic scheme
Fix the valve to the pressure flow by connecting BP to the higher flow pump, AP to the lower flow pump, T to the tank and M to the eventual manometer. Flange the solenoid valve to the VABP and connect ports A and B to the actuator.
