Oleodinamica Marchesini V0436 VBCD 1 DE A double counterbalance valve

Oleodinamica Marchesini V0436 (VBCD 1 DE A) is a double counterbalance valve rated for 150 l/min maximum flow and 350 bar maximum operating pressure. Its factory pilot ratio is 1:5.5. 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 supply and actuator connections are 1" 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.
