The valve includes two valve bodies slidably received in a bore of a housing and movable toward one another upon receiving hydraulic pressure, valve seats formed respectively in the valve bodies, a free piston assembly the opposite ends of which are mounted slidably and sealingly on the valve bodies, and valve members mounted on opposite ends of the free piston assembly and defining valve heads cooperating with the valve seats in the valve bodies.
