Servoproportionals

Digital servoproportionals are performing close to good servovalves with excellent reliability …at the top of proportional applications

Spool-sleeve precise overlapping, closed-loop feedback, fail-safe, high response, digital electronics factory preset, flow/pressure/position digital control, software setting of functional parameters, rugged option versus vibrations & shocks, ex-proof & stainless steel executions

Basic principle of operation

Proportional valves modulate hydraulic or motion parameters according to electronic reference signals. Basic principle of a proportional valve: the force of solenoid is related to the reference signal, thus properly moving the spool against a return spring to modulate hydraulic parameters
