DST Tools 5" Ful-Flo Hydraulic Circulating Valve
Size: 5", 3 7/8", 4 5/8"
Product mode:Ful-Flo Hydraulic Circulating Valve
Working pressure:10000psi ~ 15000psi
Certification: API, ISO
Usage: drill stem testing
Working condition: High pressure high temperature(HPHT)
The FUL-FLO hydraulic 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.
Features and Benefits
• Permits passage of wireline tools through its full-opening bore
• Requires no pipe rotation to operate
Bypass ports close when weight is set down and reopen when weight is lifted.
A hydraulic metering system provides a 2 to 3-minute delay in closing after weight is applied. This delay allows either the RTTS packer to be set or the test string to be stung into a permanent packer before the bypass ports close. The ports reopen without a time delay.
During stimulation work, the latching piston adds a downward force on the circulating sleeve to help keep the valve closed.
Operation of the valve is the same whether it is used as a circulating valve or as a bypass. No torque is required. Weight is applied to close the tool, and the workstring is picked up to reopen it.
