Abstract
A valve for use between a first fluid side and a second fluid side is disclosed herein. The valve comprises a pair of subassemblies, each one slidable between a closed position and an open position. Each subassembly comprises a first component comprising a first component main body, a first component first end and a first component second end opposite the first component first end. A first component first extension is formed on each first component first end, the first component first extension comprising a diameter that is less than the diameter of the first component main body. Hydraulic pressure causes one subassembly to slide to its closed position, and causes it to engage the second subassembly, sliding the second subassembly to its open position.
