New Combi valves from Siemens

02 February, 2012

Siemens has extended its proven Acvatix range by the introduction of a new range of pressure-independent control combi valves, types VPP46 and VPI46 to complement the existing VPI45 range. These have a control valve for temperature control, a differential-pressure controller for balancing pressure fluctuations in the hydraulic system, a facility for pre-adjusting the required flow rate, and pressure test points for measuring the differential pressure — all integrated in one valve body. They reduce planning, installation and commissioning costs, and increase the control accuracy under all operating conditions, leading to increased energy efficient operation.

Balfour Beatty, Metstrut, cable management

Metstrut, the cable-management division of Metsec, has been selected as a preferred supplier by Balfour Beatty Engineering Services.

SAV Systems, commissioning, flow measurement

As buildings have become better insulated, with lower space-heating demands, variable-volume hydronic heating systems have become much more common. As a consequence, commissioning engineers often find themselves dealing with ultra-low flows (<0.015 l/s) which are too low to measure accurately and consistently with standard flow-measurement devices.
