Abstract
A probe activated valve system is disclosed that permits easier and safer testing of fluids in a pressurized system. The system has a shell having a valve passage. The valve passage has an end through which the valve passage is fluidly connected to a probe passage. A valve seat is provided at the end of the valve passage. A valve sealing member forms a face seal against the valve seat by compressing a retained sealing member, such as an O-ring. The valve sealing member is moveable from a closed position to an open position, upon insertion of a probe to engage and displace the valve sealing member along the valve passage, such that the valve sealing member is spaced from the valve seat and allows fluid in the valve passage to flow to the probe passage for collection by the probe.
