The HF-PV20 replaces bang-bang switching with proportional control: spool position follows the command signal, so actuators accelerate and settle smoothly instead of hammering. That difference is what separates a machine an operator fights from one they trust.
The valve runs on standard proportional amplifiers or PLC analogue outputs, and the spool family covers meter-in, meter-out and fine-control characteristics. Manual override pins allow commissioning before the control cabinet is live.
Every valve is characterised on the flow stand and ships with its curve, so commissioning starts from data rather than guesswork.
