Proportional flow rate valve with position feedback for closed ring The RPCER1 is a two -way range proportional valve with baric and thermal compensation, with feedback, for plate assembly. The re -process of position on the flow control choker allows to obtain characteristic curves with extremely reduced hysteresis and high repeatability. It is used for the adjustment of the flow rate in hydraulic circuit branches or for the control of the speed of hydraulic actuators. It is available in five scope adjustment fields up to 25 l/min. It should be commanded with an external electronic card, such as EDM-J (catalog 89255) to be ordered separately.
