Control system for a valve assembly

A valve assembly comprising:

• a valve body (4) including a first section (6) and a second section (8), the first section (6) including an inlet member (12) and an outlet member (13) and the second section (8) including an inlet element (28) and an outlet element (29);
• and
• a control system (44) arranged between the first section (6) and the second section (8) of the valve body (4), the control system (44) including a flow direction member (48) having a through flow portion (60) including a first orifice (63) and a second orifice (64) and a bypass portion (73) including a first opening (76) fluidically connected to a second opening (77) through a bypass conduit (75) that is selectively shifted along a substantially linear path between one of a full through flow mode and a bypass mode, wherein in the full through flow mode the flow direction member (48) passes a complete fluid flow from the inlet member (12) through the first orifice (63) to the outlet element (29) and from the inlet element (28) through the second orifice (64) to the outlet member (13), and when in the bypass mode the flow direction member (48) passes the fluid flow from the inlet member (12) through the first opening (76) into the bypass conduit (75) to the second opening (74) and to the outlet member (13), wherein the flow direction member (48) is selectively positioned in a partial bypass mode when the flow direction member (48) passes a first portion of the fluid flow from the inlet member (12) to the outlet member (13) and a second portion of the fluid flow from the inlet member (12) to the outlet element (29).
