Oleodinamica Marchesini V0135 VBPDE 1/2 L 2 CC double pilot-operated check valve

Oleodinamica Marchesini V0135 (VBPDE 1/2 L 2 CC) is a double pilot-operated check valve. The factory maximum operating pressure is 350 bar and the maximum flow is 50 l/min.

Two pilot-operated checks retain the actuator in both directions. Each section permits supply flow towards its cylinder port and blocks return until the opposite pilot line is pressurised. Connect V1/V2 to the supply and C1/C2 to the actuator using the mounting arrangement for this execution.

The manufacturer table specifies a 1:5 pilot ratio and a catalogue cracking pressure of 3 bar. These are the standard table values for this code; optional springs and seal arrangements are separate configurations.

The V1/V2 supply ports are 1/2" BSP. The actuator-side fittings are DIN 2353 L-series for 15 mm outside-diameter tube. This tube diameter is separate from the supply thread size. The short cartridge arrangement is shown with the original banjo and pipe geometry in the local PDF.

The body is zinc-plated steel with hardened and ground steel internal components and standard BUNA N seals.
