Abstract
An apparatus for controlling fluid flow from a first location to a second location includes a body, a valve, a shear seal, and a biasing member. The body has a fluid conduit and a chamber. The conduit has an inlet that communicates with the first location and an outlet that communicates with the second location. The valve is disposed in the chamber and has a seal separating the chamber into a pressure section and a flow section. The pressure section communicates with the outlet via an outlet fluid branch. The shear seal has a movable sealing element disposed on the valve and a stationary sealing element disposed in the body. The biasing member urges the valve to a closed position wherein the stationary sealing element sealingly engages the movable sealing element. Pressure communicated by the outlet fluid branch also urges the valve to the closed position.
