DBD20G CE certificated Rexroth threaded connection G1" direct operated pressure relief valve is the direct operated threaded connection type pressure control valve, which are rely on the oil pressure in the system acts directly to the equilibrium with the spring force on the spool to control the opening and closing movement of the spool of the relief valve, the orifice in the inlet pressure oil through the spool on the pass into the spool bottom when into the oil pressure is small under the action of the spring when the spool is in the lower end position of the inlet and the oil outlet to the tank that does not flow relief.
DBD20G CE Certificated Rexroth Threaded Connection G1" Direct Operated Pressure Relief Valve
When the inlet pressure on the spool increases more than the force of the spring pressing, the spool moves forward and connects the P and T ports, the excess oil to drain back into the oil reservoir as pressure relief, the function of the orifice is to increase the valve stationary, diminish the oil pressure impulse, the force of spring can be adjusted by the adjustment bolt.
If a higher pressure or a larger flow rate control by the direct drive type relief valve, the large rigidity of the hard spring should be adopted, structural dimensions required will be large, but it is difficult to adjust the oil pressure and flow rate fluctuations, therefore, the direct-acting relief valve is generally used only for low pressure in a small flow system, or used as a pilot valve.
