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.

‘Self-balancing valves’ and ‘automatic balancing valves’ means that there is no need for a commissioning engineer. Right? Tony Anderson, chairman of the Commissioning Specialists’ Association’s training committee believes that the commissioning engineer’s role is more important than ever.

Hydraquip has launched a new range of double-shut-off couplings for the commercial H&V and air-conditioning sectors. Hydraquick couplings can be connected and disconnected without having to shut down or drain the system. Terminal units can also be looped out during the flushing process.

What do the performance gap and uncomfortable buildings that are energy inefficient have in common. Paul Wightman of Albion Valves believes poorly balanced systems are often to blame.

Belimo’s EPIV pressure-independent characterised-control valve is available in sizes from DN15 to DN150. These valves combine the four functions of measuring, controlling, hydraulic balancing and bubble-tight closing. They provide real-time information of the measured flow rate.

Grouping a number of terminal units together with a manifold offers major benefits for installation and commissioning. Nick Martin of Marflow Hydronics takes a look at their real advantages.

The only information needed to the size of Siemens Acvatix PICV (pressure-independent control valve) is the required flow through it, saving time for the specifier. These valves automatically shield against pressure fluctuations in a network to maintain a constant flow. The are available in sizes from 15 to 150 mm (a 50 mm size is pictured).

The addition of a tracer dye to its products for pre-commission cleaning is said by Water Treatment Products to be a major step forward. WTP tracer dye enables contractors to accurately measure the concentration of chemical cleaners as they are added to the system
