Abstract
A valve assembly with an automatic check valve feature and automatic disassembly feature. The valve assembly includes an actuating mechanism which keeps the valve gates open, establishing fluid communication. The fluid checking feature operates when the valve assembly is disassembled. When the valve assembly disassembles, the check valves automatically close. The valve assembly can be disassembled manually or automatically. The automatic disassembly feature includes a collar and breakable link assembly, which keep the valve assembly in sealing engagement. Upon a predetermined force, the breakable link assembly fails, releasing the collar from the valve assembly and effecting disassembly of the valve assembly.
