Drill Stem Testing Hydraulic Circulating Valve 5" x 15000 psi
The Hydraulic Circulating Valve called H-circulating valve is the part of drill stem testing string, it serves as a bypass around the packer or as a circulating valve to circulate a well after testing.When running below a closed valve, the hydraulic circulating valve 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 running above a closed valve, the hydraulic circulating valve can be used as a circulating valve when the workstring is picked up.
Features and Benefits
• The full bore design of the circulating valve permits
passage of wireline tools through its full-opening bore
• The hydraulic circulating valve requires no pipe rotation to
operate
