Dutch Finger Install Process for the Live Air ValveThe Dutch Finger is installed onto the defective valve in a fluid tight arrangement. The defective valve is opened to allow the manual insertion of the plugging finger into the pipeline opening, to a predetermined position. Manual operation of the tool contracts the finger to plug the opening, and enlarges the finger inside the pipe, restraining it from movement. The defective valve, nipple and Dutch Finger housing can be removed by lifting it up and over the tool. The new Air-valve, nipple and Dutch Finger are set over the tool and installed onto the pipeline. The Dutch finger is relaxed and pulled into the pressure tight housing and the new Air-valve is closed completing the process.

Exclusive Dutch Finger by InternationalFlow™ allows:

* Air-Valve Replacements under pressure without a shut down of system.

"We were impressed with Jason, he represented your company very well on the job in Yuma. We’ve had vendors/workers in the past who show up, fumble around and are not totally familiar with their equipment. Not the case with Jason, he was professional, prepared and jumped right in and got started."

- Craig Hochheimer,
City of Yuma, AZ

"I just wanted to take a minute to thank and commend you on your team selection and the gentleman who performed the work out here at NIH for us last week. Tom and his partner were on time, and performed their work with the utmost professionalism. This is a very high profile project for my firm and for NIH and your technicians made us look very good and in fact helped us solve a big testing problem."

- Michael McReady,

"City broke off a 2" air relief valve on a 16" ductile sewage pipeline with 45psi. Before the valve could be replaced we had to rush out and complete a 16" linestop. The linestop was successful with a 100% plug. On the left is the thank you letter from the City ."

Manager, City of Kingston, Tennessee
