The CETOP 3 bases of the BS3 series are a simple and flexible solution for the construction of hydraulic systems with only one working section. On the CETOP 3 flanging it is possible to install a directional solenoid valve, while any pressure peaks in the system are limited by a maximum pressure valve. All the mouths of the valve body have size BSPP 3/8 and are positioned laterally with respect to the CETOP valve and the limiting valve. The anodic oxidation treatment, black in color, guarantees the body a high resistance to the action of corrosive agents. For the VMD40S relief valve different types of adjustment and calibration ranges are available. BS3 bases are recommended for use in circuits with flow rates up to 40 lpm. The maximum working pressure is 210 bar.
