The key BF2N marks the version with an internal hexagon and protective cap, the figure 200 the adjustment range up to 200 bar. The pilot stage works as a poppet seat and the drained pilot flow leaves the block through the third port.

Benefits

• Pressure set from 3.7 to 200 bar by internal hexagon, protective cap guards against accidental change
• Separate pilot oil drain routed through the third port
• Flow up to 450 l/min at an operating pressure of 350 bar maximum
• Size 40 with flange connection, mass 14.72 kg
• Unloading by a built-on directional spool valve at 24 VDC, NBR seals

Application

The block protects pumps on power units for forming and clamping work carrying pressure up to 200 bar. Because the range starts as low as 3.7 bar, a low holding pressure can also be set cleanly. Circulating through the solenoid stage keeps the oil budget cool.
