Oleodinamica Marchesini V0432/SF VBCD 1/2 DE A SF double counterbalance valve

Oleodinamica Marchesini V0432/SF is the VBCD 1/2 DE A SF double counterbalance valve, listed for maximum flow of 60 l/min and maximum operating pressure of 350 bar. The current factory article table gives a mass of 1.886 kg.

The factory pilot-ratio designation is 1:4.5. The valve controls the return flow of an overrunning load and holds the actuator when the directional valve is idle. The two cross-piloted branches control the actuator in both directions; supply pressure on one side opens the corresponding return-side counterbalance branch.

Connect the 1/2" BSP V1/V2 ports to the directional valve, C1/C2 to the actuator and the separate 1/4" BSP SF port to the brake-release circuit. The illustrated shuttle arrangement provides the brake-release pressure signal. This Type A SF execution is distinct from the plain double counterbalance valve and the drilled-bolt FLV article.

The catalogue standard setting is 320 bar. This is a factory catalogue reference, separate from maximum component pressure and from the actual setting of a delivered unit. The manufacturer specifies a setting at least 1.3 times the load-induced pressure to permit closure at maximum load. The reference does not define a newly generated order-code configuration.

The zinc-plated steel body contains hardened and ground steel parts with standard BUNA-N seals and negligible internal leakage as described by the manufacturer.

The local technical PDF retains the complete applicable original manufacturer spread, including the exact article table, hydraulic symbol and installation drawing. Where curves specify oil at 50 °C and 30 cSt, these are reference conditions rather than operating-temperature limits.
