1. A valve assembly, comprising:
- a valve housing including a bore including an upper end, a lower end and an intermediate annular valve seat;
a first port fluidly connected at one end of the bore and a second port connected at the other end of the bore;
a low pressure inlet port and a high pressure inlet port;
a valve member slidably carried by a sealing disk sealing the bore and moveable between a closed position engaging the valve seat and blocking fluid flow through the second port and an open position permitting fluid flow through the second port, wherein a longitudinal axis of the valve member is coaxial with the first port and the second port, wherein the valve member includes a poppet having a valve stem;
a piston member having a flat surface slidably carried in the bore for moving the valve member to the closed position under pressurized conditions, wherein an end of the valve stem is engageable with the flat surface of the piston member; and
a control for selectively applying pressurized conditions to the piston member for effecting the closed position and reversely conditioned for removing the pressurized conditions and permit movement of the valve member to the open position by pressure conditions in the lower end of the bore, thereby providing two way valve functionality.

Abstract
A valve manifold includes a valve body carrying pairs of laterally spaced piston actuated valves controlled by control modules operative to selectively pressurize and exhaust an outlet port connected to a fluid device and configured in groupings permitting varying valve functionalities.

19. A valve assembly, comprising:
-
a valve housing including a bore including an upper end, a lower end and an intermediate annular valve seat, wherein the valve housing includes a first portion and a second portion attached to the first portion; a first port fluidly connected at one end of the bore and a second port connected at another end of the bore, wherein the first portion includes the first port and the second portion includes the second port; a low pressure inlet port and a high pressure inlet port; a valve member slidably carried by a sealing disk sealing the bore and moveable between a closed position engaging the valve seat and blocking fluid flow through the second port and an open position permitting fluid flow through the second port, wherein a longitudinal axis of the valve member is coaxial with the first port and the second port, wherein the valve member includes a poppet having a valve stem; a piston member having a flat surface slidably carried in the bore for moving the valve member to the closed position under pressurized conditions, wherein an end of the valve stem is engageable with the flat surface of the piston member; a control for selectively applying pressurized conditions to the piston member for effecting the closed position and reversely conditioned for removing the pressurized conditions and permit movement of the valve member to the open position by pressure conditions in the lower end of the bore, thereby providing two way valve functionality; and a pilot pressure line in fluid communication with the first port. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
