The CIM 747.1 balancing valve is manufactured in accordance with EN ISO 9001 and is designed to provide high accuracy flow balancing and measurement across all valve settings. The CIM 747.1 balancing valve is available in valve sizes from 1/2" through 2" and is manufactured of corrosion resistant brass. It is suitable for both heating (LPHW) and cooling applications at working pressures up to 232 PSI.
• A compact body design integrating a fixed orifice and test points permitting high accuracy flow measurment to within +/- 5% regardless of valve setting.
• A metal to metal thread locking mechanism designed to accurately lock valve settings enabling the valve to be closed and re-opened to its exact pre-set position.
• A flip-up cap housing individual Allen key for valve position locking.
• Heat and impact resistant nylon non-rising handle with a 360º re-settable index collar and indicator scale which can be read from any angle.
• An EPDM lined valve plug designed to provide increased control and tight shut-off for isolation purposes.

The CIM 747.1 balancing valve has been tested by
BSRIA with water containing high air and dirt levels.
Testing results demonstrated an excellent tolerance to
such conditions providing confidence that the valves will
retain a high level of accuracy and repeatability of flow
measurement under even the worst system conditions.
