Description

Oleodinamica Marchesini V0091 (VBPDE 1/4 L 2 CEXC - 10L) is a double pilot-operated check valve. The factory maximum operating pressure is 350 bar and the maximum flow is 20 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 1:5.5 pilot ratio and a catalogue cracking pressure of 7 bar. These are the standard table values for this code; optional springs and seal arrangements are separate configurations.

The V1/V2 supply ports are 1/4" BSP. The actuator-side fittings are DIN 2353 L-series for 10 mm outside-diameter tube. This tube diameter is separate from the supply thread size. The extra-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. The local PDF preserves the complete relevant manufacturer ratings, schematic, dimensions and conditions. Representative manufacturer product image for the VBPDE 2 CEXC series.
