TR6 thermostatic expansion valve installations

In this video, we review how to complete a typical installation of a Danfoss TR6 thermostatic expansion valve. We cover disconnecting the liquid line, brazing the outlet fitting, and installing both the temperature sensing bulb and equalization line.

Danfoss team or Representatives seem to know exactly how to demonstrate and teach clearly. I like and appreciate that.

[@hermantosatrioelectric]

Its good. Thanks for this video share

Very detail to the point l love it

wait for hot enough before apply braze rod, tight txv equalize nut with 2 wrenches

What happened to pulling a vacuum?

[@OnePointLander]

Is this a non bleed hard shut off txv?

[@Pennconst101]

Are TXV’s universal and that a 3 ton can be installed on any 3 ton? Obviously the fittings are important but so long as it fits. There has been much debate within my company over this. We’ve had instances where we need a 2 1/2 ton outdoor TX me and we have a 2 1/2 ton That will work

[@DanfossNorthAmerica]

Hello, A 3 ton valve will fit any 3 ton unit as long as both are rated from the same nominal capacities. If you're unsure about this, our Coolselector software can help confirm the capacity of the valve at specific conditions. www.danfoss.com/en-us/service-and-support/downloads/dcs/coolselector-2/

May i know in clip 1.26 minutes you joined in suction is what?

[@DanfossNorthAmerica]

Hi Chandra, in the video at 1:26 the instruction is that the sensing bulb and equalization line should be installed to the suction line after the header. For more help with TR6 installations, download the guide here: www.danfoss.com/en-us/search/?query=AN000086419860

remove schrader valve core before putting the equalizer line on, right?

[@DanfossNorthAmerica]

yes, remove before attaching the equalization line to the port.

Check the denfos catalog which is mentioned in the box packing of denfoss valve

Shouldn't I flow nitrogen while brazing?

[@DanfossNorthAmerica]

Hi mdimascio, This video was created for instructional purposes in one of our application centers to help technicians understand how to install a TR6 thermostatic expansion valve. It is necessary to flow nitrogen when brazing any copper or brass refrigeration fitting. The nitrogen prevents the formation of copper oxide which will move through the system and possibly block the orifice in the TXV and, if it is a heat pump, damage the reversing valve.

Why external equalizer line used in txv?

[@DanfossNorthAmerica]

Hi Neel, generally, in larger systems that are over 1 ton capacity, external equalization is necessary. The same goes for any system utilizing a distributor. Currently, the TR6 thermostatic expansion valve is available in capacities of 1.5 ton to 6 ton depending on the refrigerant used, making external equalization the preferred route. If there is a specific system you are working with and have questions on, your local Danfoss technical support team is available to assist. store.danfoss.com/us/en_US/find-a-distributor”

[@neelpunghera2639]

@@DanfossNorthAmerica thank you for your reply. Positively looking forward to business with you.✌🏻

[@joecox9958]

Danfoss web has poor documentation nor tell customer its TxV is hard shutdown or not. nor I know the type in video using which kind of pipe size/thread.

[@DanfossNorthAmerica]

Hi Joe, Have you tried reviewing our TR6 product page? This will hopefully provide some answers you are looking for. www.danfoss.com/en-us/products/dcs/valves/thermostatic-expansion-valves/tr-6-thermostatic-expansion-valves/

[@backhoeprojects9262]

you don't charge by super heat with txv so why check it unless there is a problem. The instructions usually say 10 o'clock or 2 o'clock for the bulb position on the pipe. I do not think you tightened the fittings to proper torque. And its never that clean or well lit not realistic must be a fake video. Probably a guy who has never changed one before only in the books.

[@DanfossNorthAmerica]

Thanks for the feedback, Batman 1999. This video was created for instructional purposes in one of our application centers to help technicians understand how to install a TR6 TXV. As a good field practice we encourage technicians to check the superheat before leaving the job after the system has had time to equalize to ensure any adjustments to the valve are needed or not and to ensure it is regulating superheat properly. If you have any additional questions or need assistance with your TXV installations, our tech support is available to help you at 1(888)DANFOSS or [e-mail].
