Oleodinamica Marchesini V0606 VRC 3/8 bidirectional check valve

Oleodinamica Marchesini V0606 is the VRC 3/8 bidirectional check valve with 3/8" BSP connections. The current factory table specifies maximum flow of 35 l/min, maximum pressure of 350 bar and mass of 0.448 kg. Its opposed branches open at different pressures: 0.5 bar from V to C and 8 bar from C to V.

Select the supply connection according to the required circuit function. The two directional cracking pressures must remain separate; 8 bar is an opening threshold in one direction, not the component maximum pressure or an adjustable relief range.

The zinc-plated steel body contains hardened and ground steel parts. The drawing lists length L of 100 mm with 27 mm and 30 mm hexagons. The local PDF preserves the labelled V/C circuit and both pressure-drop curves.

The local PDF retains the complete applicable original manufacturer spread, including the article table, hydraulic symbol, drawings and ordering notes. Where curves specify oil at 50 °C and 30 cSt, these are curve reference conditions rather than an operating-temperature limit.
