Description
The letter H in the key BH2N stands for the high-pressure flange, the figure 315 for the upper limit of the setting. An internal hexagon under the protective cap takes the adjustment and the pilot stage closes as a poppet seat.
Benefits
- Pressure adjustable from 3.7 to 315 bar, laid out for high-pressure circuits
- High-pressure flange with 2 ports, no separate pilot oil line required
- Flow up to 450 l/min at a maximum operating pressure of 350 bar
- Mass 14.38 kg, NBR seals, HL hydraulic fluid
- Built-on directional spool valve, 2 switching positions at 24 VDC
Application
The block goes on power units of forging presses, tool clamps and hydraulic test rigs working around 315 bar. The protective cap over the internal hexagon keeps a setting that should not change during operation. Circulation through the solenoid takes load off the pump during pauses.
