DBD10G threaded connection G1/2" Rexroth direct operated pressure adjustment relief valve 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.
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.
