Marchesini VS2C direct-acting sequence valve, 3/8" to 3/4", with several setting springs.
The VS2C is mainly used to run two cylinders in order: when the first one finishes its stroke and the pressure reaches the set value, the valve opens from V to C and feeds the second one. From C to V oil returns freely through the built-in check valve. As it is direct acting, the pressures add up, so it suits circuits where the second actuator works at low pressure.
Maximum pressure 350 bar. Springs for 3/8" and 1/2": 10-50, 20-100, 10-180 (standard), 50-250 and 80-300 bar; for 3/4": 20-200 and 50-400 bar (standard). PP versions are prepared for a sealing cap. The list includes V0640/PP100, V0660/50, V0660/180, V0660/PP100, V0665, V0665/50 and V0665/200.
