Flow-limiting valves help maintain low system temperatures

commissioning, balancing, SAV Systems, valve, TRV

The PT40 range of radiator control valves from SAV Systems helps to reduce energy waste in heat networks by ensuring that radiator systems are well balanced. These TRV sets are presettable to a flow-rate limit at each radiator, in line with the CIBSE ‘Heat networks code of practice’, eliminating the need for traditional balancing.

Built-in differential-pressure control ensures that flow rates are not affected by pressure fluctuations in the system, and there is no need for a radiator to act as a system bypass. This ensures that one radiator does not deprive differential pressure required elsewhere in the system and that low system temperatures are maintained.

Less water circulates through the system, so the performance of the heating-circuit pump is optimised, saving even more energy.

The PT40 range includes right-angle and straight valve sets There is a choice of threaded steel and copper connections. Valves can be supplied with remote sensors, adjusters and tamperproof options if required.

The system can be flushed with the valves in place.

‘Red tape scrapping is welcome – but more policy changes are needed’

The CEO of heat pump manufacturer Aira UK has said the government’s new proposals to scrap planning red tape for the installation of heat pumps in the UK will be a big breakthrough for the industry and consumers – but more policy changes are needed.

New procurement rules for NHS suppliers

New procurement rules mean NHS suppliers will need to demonstrate their green credentials so the NHS can achieve its target of becoming net zero for directly-controlled emissions by 2040, with an ambition to reach an 80% reduction in its carbon emissions between 2028 to 2032.
