Description

The component ThrottleCheckValvePT1 is a model that combines a throttle and a check valve. If pressure p2 > p1 the flow passes the throttle only whereas if the pressure p1 > p2 the flow will be distributed over throttle and check valve according to the respective resistances.

The opening condition is:

fluidPortA.p > fluidPortB.p + Opening pressure difference.

Max. opening pressure difference defines the point where the check valve is completely open and the values Nominal volume flow and Nominal pressure difference apply. From Opening pressure difference to Max. opening pressure difference the flow is scaled proportionally.
