IMI TA / Control valves / TA-FUSION-P NPT threads / ANSI flanges TA-FUSION-P NPT threads / ANSI flanges These innovative pressure independent balancing and control valves for heating and cooling

2 IMI TA / Control valves / TA-FUSION-P NPT threads / ANSI flanges TA-FUSION-P NPT threads / ANSI flanges These innovative pressure independent balancing and control valves for heating and cooling systems combine the key hydronic functions of balancing and control in one valve. Adjustable maximum flow and inherent independent EQM characteristics allow correct valve sizing and optimum system controllability. The measuring points enable accurate measurement of flow, differential pressure, temperature and available differential pressure. Key features > > Adjustable maximum flow Adjustable Cv max technology allows setting to design flow. > > Independent, inherent EQM characteristic Proper EQM valve characteristic and high authority for all settings. > > Self-sealing measuring points Simple and accurate measurement for balancing, trouble shooting and power measurement.

Correction factors The flow calculations are valid for water (68 F). For other liquids with approximately the same viscosity as water ( 20 cst = 3 E=0S.U.), it is only necessary to compensate for the specific density. However, at low temperatures, the viscosity increases and laminar flow may occur in the valves. 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 HySelect or directly in our balancing instruments. Noise In order to avoid noise in the installation, the valve must be correctly installed and the water de-aerated. Sizing Example Flow is 22 gpm, available ΔpV is 2.9 psi and control signal (input signal) is 0- VDC, supply voltage 24 VAC. 1. Go to sizing diagram. 2. Draw a straight horizontal line from 22 gpm, which will cross the setting bars for all valves which fit the application. In this case size 1 1/2 setting 8.5, 2 setting Check that the available ΔpV is within the working range (between min. and max. allowed ΔpV). Min. ΔpV is valid for setting, other settings will require slightly lower ΔpV, this can be checked with the software HySelect. 4. Choose the smallest option (with some safety margin). In this case size 1 1/2 is preferable. See Articles Valves. 5. Go to Selection of actuator to select the actuator. In this case TA-Slider 750, article number

Maximum recommended pressure drop (ΔpV) for valve and actuator combination The maximum recommneded pressure drop over the valve and actuator combination for close off (ΔpV close ) and to fulfill all stated performances (ΔpV max ). ΔpV close = The maximum pressure drop that the valve can close against from an opened position, with a specified force by actuator. (Without exceeding stated leakage rate.)
