Claim:
1. An apparatus for managing the flow of fluid through a pipe comprising: a housing forming an internal chamber having an inlet opening and an outlet opening wherein pressurized fluid flows through the housing; a poppet valve mounted to a shaft and disposed within the internal chamber, the poppet valve configured to contact a seat in proximity to the inlet opening wherein unseating the poppet valve from the seat opens a seat passage allowing fluid to flow therethrough, wherein an inlet passage runs from the inlet opening to a transitional element between the inlet passage and the seat passage, wherein the first surface has a conical taper from the inlet opening to the transitional element, wherein the size of the inlet passage at the inlet opening is larger than the size of the inlet passage at the transitional element, and further wherein the seat passage has a conical taper from the transitional element to a distal end thereof, wherein the size of the seat passage at the transitional element is smaller than the size of the seat passage at the distal end thereof, and further wherein the conical taper of the first surface has an angle that is larger than an angle of the conical taper of the seat passage; a base plate spanning a cross-section of the housing in proximity to the outlet opening, the base plate having a central opening slidably receiving the shaft, an internal surface, and at least one aperture for allowing the flow of fluid therethrough; a spring around the shaft having a first end and a second end, wherein movement of the poppet valve toward the base causes a compression of the spring and allows water to flow through a passage through the seat; and at least one channel disposed in proximity to the inlet opening and connecting the space at the inlet opening to the internal chamber, the passage configured to bypass the passage through the seat and further configured to allow a flow of fluid from the space at the inlet opening to the internal chamber.
