Draining optional
Valves with draining for 3/4" NPS hose connection.
Valves without draining have a sleeve. This sleeve can
temporarily be removed and a draining kit be fitted, which is
available as an accessory.

- Page 3 This causes a flow deviation that increases with small valves, low settings and low differential pressures. Correction for this deviation can be made with the software TA Select or direct in TA-CBI.
- Page 4 Support material Software TA Select: Makes it easy to choose the right balancing valves by taking into account the desired flow, pressure drop and flow rate. Measuring instruments Use the TA-CBI electronic instrument. It is programmed with valve characteristics for TA valves, enabling measured differential pressure to be read off directly as a flow rate.
