PRE(D)*K - Explosion-proof pressure relief proportional valves ATEX, IECEx and INMETRO

— PRED3K* and PRE*K* are explosion-proof pressure relief valves with proportional control.
— They are compliant with ATEX, IECEx and INMETRO requirements and are suitable for use in potentially explosive atmospheres, for surface plants or mines.
—  A low temperature version (up to - 40 °C) is also available.
— The valves can be controlled directly by a current power supply or by means of an electronic control unit, to exploit valve performance to the full.

EDM-M* - Amplificateur numérique pour valves proportionnelles en boucle ouverte

La carte EDM-M* est un amplificateur numerique pour la commande en boucle ouverte de valves proportionnelles, realisee pour le montage sur guides type DIN EN 50022.

Il delivre une courant proportionnel au signal de consigne et independant des variations de temperature et d’impedance de charge.

L’alimentation du solenoide par l’intermediaire de l’etage PWM permet une reduction importante de l’hysteresis de la valve et une amelioration significative de la precision du reglage.

La carte est disponible en trois versions principales pour la commande de valves mono-solenoide (M1), double solenoide (M2) et a deux canaux independants pour la commande de deux valves mono-solenoide (M3). Chacune de ces versions est disponible avec des reglages differents de courant maximum et des frequences de switching (PWM) optimisees en fonction du type de valve a commander.

Le reglage des parametres s’effectue par clavier et display, sur la face avant de la carte, ou par ordinateur portable via RS232 ou par un convertisseur USB (logiciel EDMPC/20).

PRED3 - Limiteur à commande proportionnelle directe ISO 4401-03 (CETOP 03)

La valvola PRED3 è una regolatrice di pressione ad azione diretta a comando elettrico proporzionale, con superficie di attacco rispondente alle norme ISO 4401 (CETOP RP121H).

  • Viene normalmente impiegata come pilota di valvole a doppio stadio, o per il controllo della pressione in circuiti idraulici.
  • La pressione può essere modulata in modo continuo proporzionalmente alla corrente fornita al solenoide.
  • Può essere comandata direttamente da un alimentatore controllato in corrente oppure tramite le relative unità elettroniche di comando che consentono di sfruttare a pieno le prestazioni della valvola.
  • È disponibile in quattro campi di regolazione pressione fino a 350 bar.

PVD - Pompes à palettes à cylindrée variable avec compensateur de pression directe

ATTENTION: Pumps PVD9, 13, 17, 22 series 30 are no more available. The pump PVD25 series 31 is available.
PVD28 and PVD35 series 30 are no more available, too and have been replaced by PVD30 and PVD37 series 31, interchangeable. 
PVD45 series 30 will be soon out of stock and replaced by PVD48 series 31, interchangeable as far as performances are concerned but not as dimensions.
Other sizes remain in series 30.


The PVD pumps are variable displacement vane pumps with a mechanical type of pressure compensator.

  • They allow instantaneous adjustment of the flow rate according to the circuit requirements. The consequence is that energy consumption is reduced and adequate in every phase of the cycle.
  • The pump group is complete with hydrostatic axial compensation distribution plates that improve the volumetric efficiency and reduce wear of the components.
  • The pressure compensator keeps the cam ring of the pumping group in the eccentric position with use of an adjustable load spring. When the delivery pressure equals the pressure corresponding to the spring setting, the cam ring is moved toward the center, adjusting the flow rate to the values required by the plant.
  • In zero flow demand conditions, the pump delivers oil only to compensate any possible bleedings and pilotings, keeping the circuit pressure constant.
  • The compensator response times are very low such as to allow elimination of the pressure relief valve.

PVA - Pompes à palettes à cylindrée variable avec compensateur de pression piloté

The PVA pumps are variable displacement vane pumps with piloted type hydraulic pressure compensator.

  • They permit instantaneous adjustment of the flow rate according to the circuit requirements.The consequence is that energy consumption is reduced and adequate in every cycle phase.
  • The pumping group is complete with hydrostatic axial compensation distribution plates that improve the volumetric efficiency and reduce wear of the components.
  • The pressure compensator operates with the principle of keeping the cam ring of the pumping group in the eccentric position with use of a piston controlled hydraulically by a pressure pilot stage.
  • When the delivery pressure equals the pressure corresponding to the pilot stage setting, the cam ring is moved toward the center adjusting the flow rate to the plant requirements.
  • In zero flow demand conditions, the pump delivers oil only to compensate any possible bleedings and pilotings, keeping the circuit pressure constant.
  • The compensator response times are very restrained and such as to allow elimination of the pressure relief valve.
  • Also available are the versions with maximum flow adjustment PVA***Q and with the device for selection of two independent pressure values with solenoid valve PVA***M

PZE3 - Proportional 3-way pressure reducing valve, pilot operated

— The PZE3 valve is a proportional 3-way pressure reducing valve, pilot operated with mounting surface according to ISO 4401- 03 standards.
— Its main function is to control continuously the outlet pressure on A reducing the inlet pressure P. However, the valve also prevent outlet pressure exceeding its regulated pressure value discharging in T the exceeding flow (a typical case of hydraulic counterweight or load balancing).
— The pressure is modulated continuously in proportion to the current supplied to the solenoid.
— They can be controlled directly by an amplifier or a proper electronic control unit.
