It's been a few years

They had a good rep in the Utah area and were fairly common around there. Haven't seen much of them since. I'm in nB&G and danfoss country, now

I remember them being a very high quality component. Well built lots of engineering and data info supplied with them. A lot like Danfoss products.

try their website for specfics. www.tour&andersson.com

I agree with HR

They are very high quality and I believe a not-that-far rep is near Philly. I believe they service the entire NE US.

Give this number a shot: (215) 949-1550.

They may also be repped or regionalized by "Quaker Steam Speciaties" from somewhere between MA and PA

I am a TAB technician and work with a variety of BV's. Do you have any questions in particular about the TA valves?

T&A

T&A balancing valves were being marketed by Crane in the UK until about 10 years ago. Crane and Hattersley were the only two big names making commercial double-regulating (i.e., lockable regulating) valves and flow-measuring devices. Virtually all commercial heating or chilled water installations would have either Hattersley or T&A balancing valves. T&A then started marketing the valves under their own name and Crane produced their own range of valves.

The T&A valves were good quality products. I preferred the design of the locking device on the T&A balancing valves. The balancing was done by specialist contractors and I never asked them if preferred any one make.

Thanks fellas

my compliments to tp...these are some of the finest accessories that can be installed in a hydronic system. T&A goes a long way to improve the industry.

When I verify the completed balancing work in commercial buildings as part of my commissioining services, I always like to ask the technicians what they think of this or that type of air and hydronic flow control devices.

Without exception, what I hear is that the T&A balance valves are the preferred choice for T&B technicians.

You mean

there are actually balancing companies that balance Tom?

Certainly not my experience after serving on a Building Committee for two major school projects here in Ma. Funny how a balancing report can show the design CFM, installed CFM and actual CFM for a fan installed BACKWARDS.

How is commissioning addressing these type of problems?

Tom Befford,Scott Technical Service

Commisioning vs Balancing

commissioning involves four steps:
1. system readiness which includes verification of installation, review of design intent, motors bumps, rotational checks, COMPONENTS installed the correct way
2.system start-up which includes testing,adjusting and balancing,
3. verification of commissioning usually to the consultant, owner's rep or the owner
4. demonstration/documentation to owner's forces, technicians, etc.

the commissioning agent and the TAB agent need to attend all the commissioning meetings together.

if everyone on the project is awake then fans installed backwards would get noticed.
of course one time (only once...heh.heh..heh) i pointed my flashlight at the "grey" filter and declared it clean. which it was...clean plugged with years of lint!!!
one can only hope that mistakes are not too costly and that we learn from them. that's the neat thing about this industry...you need to keep an open mind ready to learn.

Tom Anderson

Yes, I know exactly what you mean. Makes me think of a hydronics balance report I once reviewed while working in consulting engineering design: 3.0 Gpm through an electric baseboard.

Poor systems balancing, among many other system performance issues, are the reasons why commissioning is becoming more common in the East.

Personally, I rarely have problems when verifying the balance report in the field. Possibly because of the knowledge that the T&B results will be randomly spot checked, and the work is done by the "A" team.

And I rarely have problems/conflicts with contractors, but almost always have difficulty with design engineers. They often get on thier high PE horse and become huffy when someone of similar or greater HVAC knowledge reviews and critique their work.

"How difficult will it be for a technician service that fan with a 30 HP motor you located 22 feet up in the air?"

"Why is there 50% more tonnage then the building needs?" etc. etc.

ask for Dan

Ken,

when calling ask for Dan. he's the TA specialist.

have the valves in stock and ship anywhere in the USA.

THANKS!

Tour and Andersson Valves

I am a Big Fan of these and others of the type (Armstrong, Oventropp). What is key is that if you are used to using a ball valve even with a memory stop, you have 90 degrees of turn to make a pressure drop. And we all know the last 45 degrees does all the work! So you have 1/8th of a turn to go from near 100% to shut-off.

Enter the 4-turn valve, 4 x 360 degrees = 1440 degrees of turn open to closed, a far cry from 45 degrees. With the larger valves (2-1/2" and up, for commercial/institutional use) they have a full eight turns or 2880 degrees.

When balancing, you turn the valve and the pressure (DP) gauge moves slowly and steadily, dead-nuts balancing. Commissioning with critical water flow management is a whole lot easier.
