— The DSPE*
are pilot operated directional control
valves with electric proportional control and
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 (see par. 15).
— They are available in CETOP P05, ISO 4401-05
(CETOP R05), ISO 4401-07 (CETOP 07), ISO
۴۴۰۱-۰۸ (CETOP 08) and ISO 4401-10 (CETOP
۱۰) sizes. Every size can be supplied with different
controlled flow rates, up to
