Patent ID: 6892999

Claim:
A probe activated high pressure sampling valve system comprising: a shell having a valve passage, the valve passage having both an axis and an end through which the valve passage is fluidly connected to a probe passage; a valve seal at the end of the valve passage, the valve seat having a face transverse to the axis of the valve passage; a valve sealing member having a face transverse to the axis of the valve passage, a deformable sealing member circumferentially compressed and retained in an annular groove protruding from one of the valve seat face or the valve sealing member face, so that the deformable sealing member is compressed in the annular groove to expose only a small portion of me deformable sealing member; the valve sealing member moveable from a closed position in which the deformable sealing member is compressed between the face of the valve sealing member and the face of the valve seat to form a face seal between the parallel faces of the valve seat and the valve sealing member to prevent fluid in the valve passage from flowing to the probe passage, to an open position, upon insertion of a probe to engage and displace the valve sealing member along the axis of the valve passage, such that the face of the valve sealing member is spaced from the face of the valve seat allowing fluid in the valve passage to flow at high velocity from a high pressure zone, having a pressure of up to about 7500 psi, to a low pressure zone, having a pressure as low as atmospheric pressure, in the probe passage for collection by the probe.
