Flow dividers type TQ and TV

The flow dividers type TQ divide (collect) total flow entering (exiting) at port C. The distribution is independent of working pressure at ports A and B, and may be divided equally or unequally in predetermined portions.

The flow divider type TV features priority division, i.e. variable flow entering port C is divided where partial flow Q_A, through port A, is kept constant and the residual flow Q_B, exits port B. As soon as one actuator's movement is stopped the flow to the other is either reduced to a minimal flow (type TQ) or completely reduced to leakage flow (type TV). It is possible to overcome this design feature by creating flow via a pressure

limiting valve.

These valves are used for applications where one pump is required to supply two unevenly loaded consumers, which must be driven simultaneously and independently (type TQ) or if one actuator requires priority flow (type TV) .
