Proportional directional control valve

A hydropneumatic cab suspension system for tractors and other agricultural machinery where a high level of ride comfort and precise damping control are required.
The PWV (Proportional-Wege-Venti) provides adaptive damping, whilst the HCS unit (Height Control System) keeps the cab height and tilt stable.

• Proportionally controlled 4/2-way throttle valve
• Used for continuous adjustment of damping during compression and rebound
• Control dependent on load, speed and surface
• High reaction speed for immediate adaptation to ground conditions
• Precise control for maximum comfort and reduced vibration transmission
• Allows dynamic hardness adjustment of the cab suspension

• Noticeably improved driving comfort thanks to adaptive damping behavior
• Immediate response to uneven terrain
• Precise and quiet operation
• High robustness for use in demanding off-road environments
