RELIEF VALVESDBDH20G1X/50V Rexroth Type DBDH Pressure Relief Valves
Parker pressure relief valves are designed such that when upstream pressure exceeds the closing force exerted by the spring, the lower stem opens, permitting flow through the valve.
Constant pressure overflow function: In the quantitative pump throttling system, the quantitative pump provides a constant flow. When the system pressure increases, the flow demand will be reduced. At this point the relief valve open, so that excess flow back to the tank, to ensure that the relief valve inlet pressure, the pump outlet pressure is constant (the valve port often with pressure fluctuations open).
Regulating effect: the relief valve in series on the return line, the relief valve to produce back pressure, moving parts increased stability.
System unloading effect: In the remote control port of the relief valve series of small flow of the solenoid valve, when the electromagnet power, the relief valve remote control port fuel tank, hydraulic pump unloading. The relief valve is used as an unloading valve at this time.
Safety protection: When the system is working properly, the valve closes. Only when the load exceeds the specified limit (the system pressure exceeds the set pressure) to open the overflow, overload protection, the system pressure is no longer increased (usually the relief valve set the pressure than the system maximum working pressure 10% to 20% ).
Practical applications are generally: for unloading valve, for remote pressure regulator, for high and low pressure multi-stage control valve, for the sequence of valves, used to produce back pressure (string in the oil on the road).
Relief valve generally has two kinds of structure: 1, direct-acting relief valve. 2, the pilot relief valve.
The main requirements of the relief valve: large voltage range, voltage deviation is small, the pressure vibration small, sensitive action, overload capacity, noise.
