A dump valve seat is mounted within the valve body. A valve plunger is mounted within a plunger shoulder cavity within the valve body and/or the middle body. The valve plunger mates with the dump valve seat. A compression spring is used to urge the valve plunger into either a seated position or an unseated position.
