Oleodinamica Marchesini V0632 VU 1 1/2 in-line check valve

Oleodinamica Marchesini V0632 (VU 1 1/2) is an in-line check valve with 1 1/2 inch BSP connections. The manufacturer lists a maximum flow of 350 l/min and a maximum pressure rating of 300 bar. These ratings identify separate selection limits; use the original performance curves and installation details to check the operating point.

The guided-poppet check element permits flow from V to C and blocks reverse flow from C to V. For this exact standard article, the manufacturer lists a cracking-pressure interval of 0.7-1 bar. Keep this interval distinct from separately ordered higher-pressure spring versions. Consult the size-specific pressure-loss curve when checking free-flow losses.

The body is zinc-plated steel with hardened and ground steel internal parts. Reference curve conditions are 50 °C oil temperature and 30 cSt oil viscosity. The local reference includes the complete relevant manufacturer spread with its code table, hydraulic schematic, dimensions, curves and conditions.
