Proportional Directional Valve 4WRGE16V200L-1X/315G24K31/C1M - Bosch Rexroth R901177144

A test rig only yields usable data if the same ramp runs identically ten thousand times. This pilot-operated proportional directional valve in size 16 meters 200 l/min nominal flow at 350 bar with external pilot oil supply, so the pilot stage works independently of load pressure.

Advantages

• External pilot oil supply plus external pilot oil return keep the pilot stage clear of working pressure.
• 200 l/min nominal flow against a 460 l/min maximum leaves headroom for peaks.
• Internal position feedback gives repeatable step responses across full spool travel.
• On-board electronics with ±10 mA command value link the valve straight to the rig controller.
• ISO 4401-07-07-0-05 pattern at 9.98 kg fits common manifold blocks.

Applications

Materials testing machines, endurance rigs, simulation axes in the medium to high flow range. Separate pilot routing suits plants where system pressure swings hard. Both pilot lines have to be provided on site.
