CRE

DIRECT OPERATED PRESSURE CONTROL PROPORTIONAL VALVE 
81100

 

The CRE valve is a direct operated pressure control proportional valve with cartridge execution which can be used in blocks and panels with type D-10A seat.  The valve is suitable as a pilot stage for remote control of two stage pressure control and reducing valves.  Pressure adjustment can be continuous in proportion to the current supplied to the solenoid.  The valve can be controlled directly by a current control power supply unit or by means of the relative electronic control units to exploit valve performance to the full.  The valve is available in three pressure control ranges up to 250 bar.

PRE*

PILOT OPERATED PRESSURE RELIEF PROPORTIONAL VALVES
81310

PRE* valves are pilot operated pressure relief proportional valves with mounting interface in compliance with ISO 6264 standards (CETOP RP 121H).  These valves are normally used to control hydraulic circuit pressure and enable the use of the full flow rate of the pump, even with settings approaching calibrated values.  The two-stage design and wide passages ensure reduced pressure drops thereby improving the system energy performance.  Pressure can be modulated continuously in proportion to the current supplied to the solenoid.  These valves can be controlled directly by a current control supply unit or by means of the relevant electronic control units to exploit valve performance to the full.  They are fitted with a manual pressure relief valve which is factory set to ≥15% of the maximum value in the pressure control range.  They are available in three sizes for flow rates up to 500 l/min and in four pressure control ranges up to 350 bar.

PILOT OPERATED PRESSURE REDUCING PROPORTIONAL VALVE
81500

 

MZE valves are 3-way pilot operated pressure reducing proportional valves, designed as modular versions with mounting interface in compliance with ISO 4401 (CETOP RP121H) standards.  The valves are used to reduce pressure in the secondary circuit branches thus ensuring stability of controlled pressure in the event of variations of the flow rate through the valve.  Pressure can be modulated continuously in proportion to the current supplied to the solenoid.  The valve can be controlled directly by a current control supply unit or by an electronic control unit, to exploit valve performance to the full.  The valve is available in three different pressure reduction ranges of up to 230 bar.  The valve is available only with internal drain to the T line inside the valve.

The DZCE* are pressure reducing proportional valves with mounting interface in compliance with ISO 4401 (CETOP RP121H) standards.  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.
