Duplomatic DSPE*J – Pilot Operated Directional Proportional Valves

~ scroll down to find the part you need ~
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 DSPE*J are pilot operated directional control proportional valves with position feedback and integrated electronics and with mounting interface in compliance with ISO 4401 (CETOP RP121H) standards.

The valve opening and hence flow rate can be modulated continuously in proportion to the current supplied to the proportional solenoids of the pilot valve. Transducer and digital card allow a fine control of the positioning of the cursor, reducing hysteresis and response time and optimizing the performance of the valve.

They are available in CETOP P05, ISO 4401-05 (CETOP R05), ISO 4401-07 (CETOP 07) and ISO 4401-08 (CETOP 08) sizes. Every size can be supplied with different controlled flow rates, up to a maximum flow rate of 800 l/min.

The valve is easy to install. The driver directly manages digital settings. In case of special applications, you can customize the settings using the optional kit.

Available in dimensions CETOP P05, R05, 07 and 08, this valve allows the adjustment of the flow rate, continuously in proportion to the current supplied to the proportional solenoids of the pilot valve.

Transducer and digital card allow a fine control of the positioning of the spool, reducing hysteresis and response time and optimizing the performance of the valve.

In the case of special applications, you can customize the settings using the optional software kit.
