Pressure Relief Valve DBW25BG2-5X/315YUS6EG24NK4R12 - Bosch Rexroth R900702959

With three ports, this pilot-operated size 25 pressure relief valve offers more freedom in line routing than the two-port builds. It limits pressure at flow up to 500 l/min and is tied in through a threaded connection.

Benefits

• Three ports for routing the drain and the pilot oil line separately.
• Threaded connection, so installation needs no subplate.
• Flow up to 500 l/min, maximum operating pressure 350 bar.
• Size 25, connection diagram to ISO 6264-08-13.
• Spool symbol B, electrical unloading from 24 VDC.
• NBR seals, HL hydraulic fluid, weight 7.18 kg.

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.
