High-Pressure Valve

A valve comprising:

• (a) a valve body having a poppet valve chamber and an axis running there through;
• (b) a removable seat having a seat inside surface, the seat located within the poppet valve chamber;
• and
• (c) a poppet having a poppet head surface, the poppet being located within the poppet valve chamber, the poppet head surface comprising two surfaces that form an intersection that is operable to removably contact the seat inside surface, and wherein the location of the poppet is dependent on the flow rate of a fluid through the valve.

A valve comprising:

• (a) a valve body having a poppet valve chamber with an axis running there through and a valve inside surface;
• (b) a removable seat having a seat sealing surface, a flow restriction surface and an outer-seat surface, the seat located axially within the poppet valve chamber;
• and
• (c) a poppet having a poppet sealing surface and a second poppet surface each having a different angle relative to the axis, and wherein the poppet sealing surface and the second poppet surface form an intersection, and wherein the location of the poppet is dependent on the flow rate of a fluid through the valve, the poppet being located axially within the poppet valve chamber;
• wherein the intersection and the flow restriction surface are operable to form a flow restriction zone for fluid flowing therebetween, wherein a poppet-seat interface is created between the seat sealing surface and the poppet sealing surface, the poppet-seat interface being at an angle β of from 20° to 90° to the axis.

A process of channeling a fluid comprising:

• (a) providing a valve body having a poppet valve chamber with an axis running there through;
• (b) providing a removable seat having a seat sealing surface and a flow restriction surface each having a different angle relative to the axis, and a groove is located between the seat sealing surface and the flow restriction surface, the seat located co-axially within the poppet valve chamber;
• and
• (c) providing a poppet having a poppet sealing surface, the poppet being located axially within the poppet valve chamber;
• wherein the valve has an open position and a closed position, and wherein a flow restriction zone is created adjacent to at least the poppet sealing surface in the range of poppet travel between the closed position and the open position such that fluid flowing through the valve chamber and past the poppet in the open position creates a local high fluid velocity zone.
