BSRIA develops test scheme for PICVs


BSRIA’s new scheme for testing and certifying pressure-independent control valves (PICVs) is set to play a key role in simplifying the selection process for these products. The scheme enables manufacturers to have their products tested to the standard and go on to achieve full certification through regular factory product control audits.

Chris Marney, certification manager at BSRIA Cert, says, ‘Although the savings in energy and commissioning time associated with PICVs are well known, uptake is hampered by a lack of specifier confidence in the payback of the products and, in some cases, a lack of understanding of variable-flow systems in general. As well as verifying performance of PICVs, BSRIA is also developing additional guidance to make PICVs a more accessible option. Ultimately, this is about reducing energy and carbon emissions, in which PICVs and variable-speed pumps have a big part to play.’

The BSRIA scheme offers a full examination of the valve, with tests for accuracy of flow setting, pressure independence, actuator control characteristic and seat leakage. The product is then certified to perform as stated by the manufacturer, which can then use the distinctive BSRIA cert mark on products, packaging and marketing output.
