Abstract
A valve includes a housing. A stroking valve is operatively connected to the housing for valve stroking movement relative to the housing in a direction of a longitudinal axis of the housing. The stroking valve has an open position for flow through the housing and a closed position for blocking flow through the housing. The stroking valve is configured to make sealing contact with a second face seal between the seal block and the stroking valve after a first portion of a stroke from the open position to the closed position prior to making sealing contact with a first face seal between the stroking valve and the housing.
