1. A valve apparatus, comprising:
a manifold having a bore, an inlet communicating with the bore, and an outlet communicating with and axially aligned with the bore;
a valve cartridge at least partially received within the bore and including a valve assembly having a valve member that enables communication between the inlet and the outlet, and an actuator assembly for actuating the valve member;
the valve assembly including a hollow valve retainer having a first end that is configured to mate with the actuator assembly and an opposite second end received within the bore and defining an outlet port that communicates with the outlet of the manifold, the hollow valve retainer including a first plate-shaped member and a second plate-shaped member connected by a pair of axially extending arms that separate the first and second plate-shaped members by a gap that serves as an inlet port of the valve retainer in communication with the inlet of the manifold, the first plate-shaped member including a first axially-extending through-hole that defines the outlet port and the second plate-shaped member including a second axially-extending through-hole that is configured for receipt of a poppet having the valve member therein,
the first plate-shaped member includes a first face that faces the gap and an opposite second face that faces the outlet of the manifold, the first axially-extending through-hole extends between the first face and the second face, and the first axially-extending through hole includes a first chamfered surface that defines a valve seat at the first face that is configured to be contacted by the valve member when the valve apparatus is in a closed position and spaced apart from the valve member when the valve apparatus is in an open position;
the poppet includes a proximate end positioned within the actuator assembly and a distal end that includes the valve member, the distal end having a radially inwardly extending groove between the valve member and the proximate end that is configured for receipt of an annular quad-ring sealing member that seals an interface between the poppet and the second axially-extending through hole of the valve retainer as the poppet and valve member are moved during operation of the valve apparatus by the actuator assembly; and
the valve member at the distal end of the poppet includes a second chamfered surface that corresponds to the first chamfered surface that defines the valve seat.
