DBW Series DBW 20 A2-5X 3156EG24NK4 Valve Type Pressure Control Valve

Proportional relief valve
Rexroth Rexroth Pilot Operated Proportional Relief Valve DBEP6B06-1X/45AG24K4M Germany
The working principle of the proportional relief valve is that the proportional relief valve changes the magnitude of the overflow pressure by changing the magnitude of the spring force. The force exerted by the proportional electromagnet on the spring can be adjusted proportionally, so the pressure of the proportional relief valve will also change as the input signal changes.
Constant pressure overflow function: In the constant flow pump throttling regulation system, the constant flow pump provides a constant flow. As the system pressure increases, the flow demand decreases. At this time, the overflow valve opens, allowing excess flow to overflow back to the tank. The inlet pressure of the overflow valve, that is, the pump outlet pressure, is constant (the valve port often opens with pressure fluctuations).
