These valves, besides reducing the pressure from line P to user A, allow the flow to return from user A to discharge T when a pressure greater than the set value is generated in the downstream circuit (user A): a typical case of hydraulic counterweight or load balancing.
The pressure can be modulated continuously in proportion to the current supplied to the solenoid.
They can be controlled directly by a current control supply unit or by means of the 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) and ISO 4401-08 (CETOP 08) sizes.
Every size can be supplied with several controlled flow rates, up to 500 l/min.
