Abstract:
A pressure control valve for downhole treatment operations includes a valve body including an inlet, an outlet, and a valve seat. A valve assembly is arranged in the valve body. The valve assembly includes a valve member selectively positionable on the valve seat to control fluid flow through the valve body. A piston assembly including a piston and a control fluid inlet is arranged in the valve body. The piston is operatively connected to the valve assembly. The piston is operable to bias the valve member toward a closed configuration upon exposure to a control fluid.
