This valve carries three ports instead of the usual two and so allows separate line routing for the pilot oil. The DBW25BG2-5X/315YUS6EG24NK4R12 protects flow up to 500 l/min in size 25 and is tied in through a threaded connection.

Application
A dedicated third port is needed when pilot oil should not be led away through the shared return line, for example at high or fluctuating tank pressure. In such plants the control behaviour of the valve stays independent of back pressure in the return.
Manufacturer
Bosch Rexroth lists the valve under material number R900702959. The function assigned to the third port is shown in the pressure relief valve data sheet (RE 25802) together with the supplement RE 25802-B.
