multi cycle circulating valve


The Multi-Cycle Circulating Valve (MCCV) is a differential pressure operated Circulating Valve which offers unlimited open and closed cycles. Shear pins hold the tool in the closed position during the run-in-hole. Once on depth, applied pressure shears the pins, allowing the tool to cycle through forward circulating, reverse circulating and closed positions.
