Abstract
Disclosed in one aspect is a valve comprising (a) a valve body having a poppet valve chamber with an axis running there through; (b) a seat having a seat sealing surface, and a outer-seat surface, the seat located axially within the poppet valve chamber; and (c) a poppet having a poppet sealing surface, the poppet being located axially within the poppet valve chamber; wherein a poppet-seat interface is created between at least a portion of the seat sealing surface and at least a portion of the poppet sealing surface, the poppet-seat interface being at an angle β of from 20 to 90° to the axis. In one embodiment the seat is removable, allowing the geometry of at least the poppet head surface and/or the seat inside surface, which defines a fluid flow-path cross-section, to be tailored.
