trv

TRV Tuna (801) was one of three Torpedo Recovery Vessels operated by the Royal Australian Navy (RAN) and Defence Maritime Services (DMS). Ordered in 1969, the vessel, originally identified as TRV 253, was completed in 1970 and assigned to the torpedo firing range at Jervis Bay. The ship received a name and the pennant number "TRV 801" in 1983. In 1988, the three vessels were sold to DMS. Tuna was assigned to the naval base at HMAS Creswell in Jervis Bay. Tuna was active in DMS service as of 2007.

    BOSS TRV replace or substitute?

    Hope this is in the right forum. We've a utility room radiator with 10mm pipework; fitted about 6 years ago it has a BOSS TRV which has failed (the sensor plunger just flops around - as if the sensor has leaked) and the radiator is always "on". I don't consider 6 years a reasonable life so I'm...

    TRV problems high pitch squealing

    Good evening - I wonder if anyone can shed some light on this. Squealing high pitch TRV's when reaching the required shut-off temp. I understand its probably the pressure in the system making the pin in the TRV vibrate. Or pump turned up too high - which I guess would cause the same effect of...

    Oil from Danfoss trv?

    I just found a small amount of a dark brown/black oily substance under a Danfoss trv that I had turned off the day before. Could this have come from the trv itself or more likely to be a slight leak from the radiator.? The system is quite old but I just moved into the house recently so no...

    Bent my TRV pin. It's not currently leaking, but could it come loose?

    Good morning! I've had no heat in my attic bedroom for over 2 years - the rest of the radiators worked fine, but this one was a dead duck. I watched some YouTube videos, and read through these forums, and decided to have a look at the TRV pin. Lo and behold it was stuck down! I managed to...

    Are Bulldog TRV valves interchangeable?

    Hi All, I have a number of Bulldog TRVs installed to my radiators (15mm pipe) and most have snapped or broken. :( I would like to replace just the TRV head (not the valve), so that I don't have to drain the rads. Are there any like-for-like alternatives that I can buy from screwfix? They have...

    Siemens Smart TRV Valve

    Hi, could anyone point me in the direction of a trv valve adapter that would fit a Siemens, thread: M28 x 1.0 mm? This is the part number referenced in a smart valve pdf which they don't supply 6296/3 EAN: 4011395232583. Also let me know if there is an alternative adapter that I could use. Thanks

    Getting a smart heating (Tado): Dynamic Valves? How important is the type of TRV?

    Hi, I'm getting a Tado smart heating system (have a gas combi boiler). I don't have TRVs currently, so I need to get a plumber to replace my old valves and get TRVs everywhere. So I might as well get good ones, and it doesn't really matter whether one costs €15 or €25. I found the Danfoss...

    Which TRV

I can get Pegler Terriers for £9 which seems okay or the Pegler Mistral for £10 If I got something like a Drayton TRV4 we are talking around £21 though that includes lockshield. A lot of lockshield valves look crap to me. I have...

    TRV

    Need a couple of anthracite coloured trvs. Reading reviews of them seems people do not like some, namely those with a spring in the lockshield end. Now in my place have fitted quite a few Pegler Mistrals which have this spring arrangement and seem fine. Is there any real difference in operation...
