Description
A narrow setpoint band gives the analogue signal a finer resolution. This size 25 safety block works from 6 to 200 bar, so the 0 to 10 V span is spread across a narrower pressure range, and it discharges up to 400 l/min.
Benefits
- Setpoint band of 6 to 200 bar, so the analogue 0 to 10 V signal resolves the pressure range finely
- On-board electronics on the valve, leaving the cabinet without an amplifier card
- Flow of up to 400 l/min at a permitted operating pressure of 350 bar
- Pilot-operated pressure stage in poppet seat design with a protective cap over the internal hexagon
- 7-pole connector to EN 175201-804, 24 VDC, NBR seals and a mass of 5.85 kg
Applications
The block suits power units with working pressures up to roughly 180 bar, for example in conveying equipment, clamping hydraulics and test installations. The control system tracks the limit pressure across the cycle. Operation on HL fluid is intended.
