Abstract
A valve is for controlling flow of a pressurized fluid to a tool. The valve has a manifold, a poppet biased into an unseated position in which the pressurized fluid may flow from the manifold via a tank outlet, a piston configured to move the poppet into a seated position when the pressurized fluid flows into the manifold via the manifold inlet at a first fluid pressure, and a check valve biased into a closed position in which the pressurized fluid is prevented from flowing from the manifold via the tool outlet. A retainer retains the poppet relative to the piston and is configured so that when the poppet is in the seated position, the piston is independently movable relative to the poppet and thus permits the poppet to remain in the seated position upon variations in fluid pressure in the manifold.
