Description
Through the third port the pilot oil leaves the block separately from the tank flow. The rotary knob sets the limiting pressure between 3.7 and 150 bar, and up to 550 l/min can drain when the valve responds.
Benefits
- Third port for the separate drain of the pilot oil
- Flow of up to 550 l/min in size 40
- Adjustment range of 3.7 to 150 bar on the rotary knob at a maximum operating pressure of 350 bar
- Electrical unloading through the built-on directional spool valve at 24 VDC
- Flange connection with a pilot-operated pressure valve in poppet seat design
- NBR seals for HL hydraulic fluid, CE conformity, weight of 14.3 kg
Applications
The block sits on power units of large delivery whose return line builds up back pressure across coolers and filters. The separate pilot routing keeps the response clear of it. The rotary knob allows the limiting pressure to follow a changed duty.
