Description
The 315 bar rating defines the adjustment range and the high-pressure flange carries the load. Two ports are enough because pilot oil returns internally. Unloading runs through a built-on directional spool valve at 24 VDC.
Benefits
- Adjustment range 3.7 to 315 bar for circuits under high working pressure
- High-pressure flange with 2 ports, size 40
- Flow up to 450 l/min at a maximum operating pressure of 350 bar
- Pilot-operated poppet seat with internal hexagon and protective cap
- Mass 14.48 kg, NBR seals, HL hydraulic fluid
Application
The block belongs on power units of presses, forging equipment and test rigs whose working pressure approaches the 315 bar mark. Between strokes the solenoid puts the pump into circulation. The high-pressure flange saves piping at the pump outlet.
