Hydraulic Circulating Valve
The Hydraulic Circulating Valve, hereafter call it as H-circulating valve, serves as a bypass around the packer or as a circulating valve to circulate a well after testing. When run below a closed valve, the tool serves as a bypass around the packer and helps relieve
pressure buildup below the closed valve when it is stung into a production packer. When run above a closed valve, the tool can be used as a circulating valve when the workstring is picked up
