Operating principle
By default, the valve remains open, allowing hydraulic fluid to flow freely back to the tank without pressurizing the system. When 24V DC is applied, the solenoid activates and closes the bypass path, directing oil into the pressure circuit to power downstream components. Once the voltage is removed, the valve reopens automatically, unloading the pump. This functionality protects the system from pressure buildup, increases operational efficiency, and extends the life of key components.
