Description

Oleodinamica Marchesini V0412/FLV (VBCD 1/2 SE A FLV) is a single 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 valve meters the controlled return flow to restrain an overrunning load in one direction. Connect V1/V2 to the supply, C1 to the actuator free-flow side and C2 to the controlled side, using the mounting arrangement for this exact execution. The integral check path allows supply flow towards the controlled actuator port.

The /FLV execution fixes directly to the actuator through the supplied drilled screw on controlled port C2. Connect C1 to the free-flow actuator side. The factory table lists 1/2" BSP nominal connections; the C2 mounting route is defined by the supplied screw and original drawing.

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.
