VA/VG 20 Crossover Relief Valve & Transition Check

Crossover Relief Valves

This valve lets high pressure to be siphoned from one port to another. So long as the spool is in neutral so it want over run the motor while acting like a pump and pressurizing the system so it want overload as it was meant to. And it is an anti cavitation protector to the other port.

Transition Check

They help ward off pressure from returning the flow, while the work sector spool is shifted. It lets the holding action give a smoother cylinder or motor control. It provides pressurized return flow til there is a necessary pressure that will be opened in the opposite passage. They come standard on all cylinder work sectors and they are not considered load hold checks.
