Duplomatic Oleodinamica designs and produces a complete range of hydraulic components that are suitable for all application sectors of both industrial and mobile fields.

The Duplomatic RPCER1 valves is a pressure and temperature compensated two-way flow control proportional valve, CETOP 03, with mounting interface in accordance with the ISO 6263 (CETOP RP121H) standards. The position feedback of the flow rate controlling throttle gives regulation conditions featuring highly reduced hysteresis and high repeatability. It is normally used to control the flow rate into an arm of the hydraulic circuit or the speed of the hydraulic actuators.

The flow rate can be modulated continuously in proportion to the reference signal sent to the electronic control unit. It is available in five flow rate control ranges up to 25 l/min
