VALVE FOR HIGH PRESSURE ANALYTICAL SYSTEM

摘要

A high pressure valve, comprising a stator having a stator sealing surface with at least one stator port and a rotor having a rotor sealing surface with at least one rotor port or channel. The rotor is movable with respect to the stator to selectively move the rotor port or channel into and/or out of alignment with the stator port thereby to open and/or close the valve. The stator port is provided by a passage with a first part that extends perpendicularly from the stator sealing surface and a second part that extends from the first part in a direction that is other than perpendicular from the stator sealing surface.
