A decoupled check-relief valve for use in a hydraulic fluid circuit is provided
that has a cylindrical guide housing which travels during the check function of
the valve. The cylindrical guide housing has a clearance parameter, allowing for
the selection of an optimal check response time. A dampening disk is provided inside
the cylindrical guide housing, traveling within the guide during the relief function
of the valve. The dampening disk has a separate clearance parameter, allowing for
the selection of an optimal dampening capacity and fluid circuit stability. As
such, the check and relief clearance parameters are independent of each other to
allow both the check and relief functions of the valve to be optimized.
