Oleodinamica Marchesini V0423 VBCD 1/2 DE A CC double counterbalance valve

Oleodinamica Marchesini V0423 (VBCD 1/2 DE A CC) is a double counterbalance valve rated for 60 l/min maximum flow and 350 bar maximum operating pressure. Its factory pilot ratio is 1:4.5. The manufacturer lists a standard setting of 320 bar; this catalogue setting is separate from the maximum pressure rating.

The two counterbalance sections control load-driven actuator movement and retain the load in both directions. Pilot pressure opens the appropriate controlled return path, while the integrated check paths permit supply flow. Connect V1/V2 to the supply and C1/C2 to the actuator as shown in the original hydraulic schematic.

The CC execution is specified for closed-centre circuits. The manufacturer describes it as insensitive to return back pressure and suitable for applications where a standard overcentre valve does not control the load correctly. This identifies the counterbalance design compatibility, rather than a centre position of a directional spool inside this valve.

The supply and actuator connections are 1/2" BSP. The type designation, pilot ratio and port layout identify this execution; a type-A, closed-centre, flange-mounted or different-ratio article must be selected by its own exact code.

The manufacturer specifies a valve setting at least 1.3 times the load-induced pressure. Check the circuit setting against the actual load; no customer-specific adjustment or /P or /PP option is inferred from this standard article code. The body is zinc-plated steel with hardened and ground steel internals and standard BUNA N seals.
