Pressure Relief Valve DBW 25 BG2-5X/200-6EG24N9K4/12 - Bosch Rexroth R978916305

Not every machine may be allowed to climb to 315 bar. This version is limited to a setting range of 3.8 to 200 bar, which protects consumers rated well below the 350 bar the housing itself withstands. Pressure stays steady at 500 l/min and a 24 VDC coil switches the circuit to unloaded operation.

Advantages

• Setting range 3.8 to 200 bar inside a housing released for 350 bar operating pressure
• Flow up to 500 l/min in size 25
• Unloading through a mounted directional spool valve, 24 VDC, two switching positions
• Threaded connection with two ports to connection diagram ISO 6264-08-13
• 6.5 kg, poppet seat pressure stage with internal hexagon and protective cap
• NBR seals for HL hydraulic fluid

Application

A good fit for clamping and feed circuits whose consumers are rated for 200 bar. Because the pilot spring caps the range, an operator cannot dial the system above what the machine was designed for. On test rigs the same function serves as a second safety stage behind the pump controller.

Manufacturer

Bosch Rexroth lists the valve as material number R978916305 in the DB.10-30 family. Pressure and flow behaviour are documented in the data sheet.
