  BSRIA launches pressure valve test scheme

BSRIA’s launches new test and certification scheme for pressure independent control valves (PICVs).

The scheme allows manufacturers of PICVs to have their products tested to the standard and go on to achieve full certification through regular factory production control audits. This provides specifiers and buyers of PICVs with increased confidence in the manufacturers’ claimed performance and consistency of production.

As part of this scheme, the new standard test method was developed by BSRIA in cooperation with ten manufacturers and a major contractor to ensure its universal suitability.  It offers a full examination of the valve, with tests for accuracy of flow setting, pressure independence, actuator control characteristic and seat leakage.

The certification operated by BSRIA Cert, requires testing to the new standard plus evidence of robust factory production control. The product is then certified to perform as stated by the manufacturer, who may then use the distinctive BSRIA Cert mark on products, packaging and marketing output to demonstrate their commitment to delivering quality products to the market.

Chris Marney, Certification Manager at BSRIA Cert, said: “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, to which PICVs and variable speed pumps have a big part to play”.
