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 DSPE* are pilot operated directional control proportional valves with mounting interface in compliance with ISO 4401 (CETOP RP121H) standards. The valve opening (and hence the flow rate) can be modulated continuously in proportion to the current supplied to the proportional solenoids of the pilot valve.
They can be controlled directly by a current control supply unit or by means of the relative electronic control units to exploit valve performance to the full. They are available in CETOP P05, ISO 4401-05 (CETOP R05), ISO 4401-07 (CETOP 07), ISO 4401-08 (CETOP 08) and ISO 4401-10 (CETOP 10) sizes. Every size can be supplied with different controlled flow rates, up to 1600 l/min.
