High flow direct acting valve

A valve including:

• a valve housing including a first port and a second port, wherein the first port acts as one of an inlet or an outlet and the second port acts as the other of the inlet or the outlet;
• a valve seat having a valve seat surface that circumscribes a longitudinal axis;
• and
• a valve member that is moveable along the longitudinal axis, wherein the valve member includes a first axial end that faces the valve seat surface and a second axial end that faces away from the first axial end, wherein when the valve member is in an open position, the first port and the second port are fluidly connected, and when the valve member is in a closed position, the first port and the second port are fluidly disconnected;
• wherein the valve member includes:
• a radially outwardly extending skirt that circumscribes the longitudinal axis and is disposed axially between a valve seat engaging surface of the first axial end and the second axial end of the valve member, whereby when a pressure at the second port is lower than a pressure at the first port, and the valve member opens, a high pressure zone forms adjacent the skirt axially between the skirt and the valve seat surface to reduce an amount of force needed to open the valve member.

• wherein the valve member includes:
• an axially extending nose that defines a flow path that extends from an opening in the first axial end towards the second axial end to allow fluid to flow within the nose, and the nose extends axially away from the second axial end of the valve member beyond a focal point, wherein the focal point is defined by an intersection of imaginary projection lines that extend along flow paths formed between the valve member and the valve seat surface;
• whereby when a fluid within the second port has a pressure that is higher than a pressure of fluid within the flow path defined by the nose, and the valve member opens, a high pressure zone forms in the first port about the nose and the flow path receives lower pressure fluid from a low pressure zone that is axially beyond the high pressure zone and that is adjacent the opening in the nose to prevent an increase in the amount of force needed to open the valve member.
