Description
The 50 bar rating gives a fine resolution for systems where a few bar of difference matter. The pilot stage is built as a poppet seat and unloading is handled by a built-on directional spool valve at 24 VDC across 2 switching positions.
Benefits
- Adjustment range 3.7 to 50 bar, fine resolution for low holding pressure
- Flow up to 450 l/min at an operating pressure of 350 bar maximum
- Flange connection in size 40 with 2 ports
- Internal hexagon with protective cap secures the chosen setting
- Mass 14.64 kg, NBR seals, connector 3-pole (2 + PE) according to EN 175301-803
Application
The block suits power units in conveying equipment, cooling and flushing circuits that stay below 50 bar while moving a large flow. It also guards the low-pressure stage of a two-stage system. When the machine rests, the solenoid takes pressure off the pump.
