Caleffi - 22mm Inlet Control Multibloc Valve Group 533002CST

Product Information

This multibloc is comprised of a pressure reducing valve, a pressure relief valve, and an internal check valve. I'm afraid I don't have much knowledge of these items - I do have a PRV fitted in my own home (and a Caleffi as it happens) but I'm not aware of it having a safety release valve on it. It has been reconfigured from the original in that the 15mm outflow pipe is an easier connection due to it now being a swivel connector. Do you have a anti-'water-hammer' vessel fitted in a place where it could get really hot during the day, enough to cause the pressure to climb? The item may be missing the original packaging or protective wrapping, or may be in the original packaging but not sealed.

This inlet pressure, in general, is too high and variable for domestic systems to operate correctly. I presume this safety valve it in case the pressure on the domestic side increases too high for some reason? These Caleffi inlet control groups are designed to control the pressure on the mains supply of an unvented hot water cylinder. The unit comprises of a manifold containing a pressure reducing valve, a cold water balancing port with check valve, a check valve and a preset pressure relief valve. months ago and had the full thing replaced, as the 6 bar safety release , although part of full thing, can be replaced separately.This amount includes seller specified domestic postage charges as well as applicable international postage, dispatch, and other fees. Or, could your PRV be allowing some flow-by during the night or day when there's no-one running water, and it's allowing the pressure on the domestic side to creep up to the point it drips out the safety valve? Pressure reducing valves are devices which, when installed on a private plumbing system, reduce and stabilise the inlet pressure from the water mains.

Another possibility that I forgot to mention is that the expansion vessel could be undersized - if the EV cannot cope with the amount of hot water expansion in the system it will then have to go somewhere else (the PRV). li>

Comprising a pressure reducing valve, a pressure relief valve and check valve, fitted all together in a single inlet control multibloc valve. The charge in the expansion vessel should be the same as the incoming pressure that is set/ controlled by the pressure reducing valve.I'm struggling to think of anything that would cause the 'trapped' domestic side to increase like this. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. Caleffi is a decent make, I understand, but these fellows - well, the safety-release-valves - are prone to allowing a drip through after they've been activated.

  I would imagine the safety release valve same as the one on the actual hot water tank are there to act if pressure goes to high. uk/caleffi-altecnic-inlet-control-group-valve-unvented-3bar-22mm-109104007 220114 Caleffi Altecnic Inlet Control Group Valve Unvented 3Bar 22mm https://www.

But thought best to change the whole thing, and now 6 months later dripping again, to my knowledge not been activated, so annoying faulty again after such short period? It is designed to protect the unvented cylinder by controlling the main supply pressure that goes to the tank and is not designed to regulate the pressure of the entire property.Read more about the condition New other (see details): An item in excellent, new condition with no wear. it is a pressure reducing valve (3 bar) on the main inlet feed with a 6 bar safety release valve, it is the safety release valve that is dripping into the tundish, it was doing this approx. Pressure reducing valves (PRV) are installed in domestic water systems to reduce and stabilise the inlet pressure from the mains supply, which is generally too high and variable for domestic appliances to function properly.
