DST 5"  Hydraulic Circulating Valve for Sale

Product Introduction

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 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-min delay in closing after weight is applied. This delay allows the RTTS packer to be set or the test string to be stung into a permanent packer before bypass ports close. The ports reopen without a time delay.

During stimulation work, the latching piston adds an additional 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.
