Introduction Introduction Open-colose applications Typical applications Energy savings and the reduction of the leakage losses will become ever more important in the future. The generation outputs of boilers or chilling systems are divided up into different performance level categories. Depending on the decline in pressure, the generators will then be switched either on or off. The generators will be blocked in order to minimise performance loss. The leakage rate (shut-off seat) shall be kept as low as possible. The pressure loss shall also be low with the faucet opened completely. These are prerequisites for minimising the electrical performance of the pumps and thus for lowering operating costs. I II III Boiler sequence system Open heat exchanger Control mode Typical applications The BELIO butterfly valves exhibit a nearly equal-percentage characteristic curve in accordance with VDI 176 for opening angles between 0 and 54 and can also be installed in injection circuits or heat exchangers with low differential pressures as an inexpensive final controlling element.

Butterfly valves for control mode Project planning Relevant information Pipeline clearances The data, information and limit values listed on the data sheets and mounting instructions D6.. are to be taken into account and/or complied with, respectively. The minimum clearances between the pipelines and the walls and ceilings required for project planning depend not only on the valve size but also on the selected actuator. Design and dimensioning General information Butterfly valves can be used in control mode when the following values are complied with: The maximum flow speed of 4 m/s may not be exceeded in the butterfly valve. The butterfly valve is to be designed in such a way that the nominal pipe width corresponds to nominal butterfly valve width. The narrowing of the pipe must be designed in such a way thereby as to ensure optimum flow in order to ensure that the pressure drop is kept as low as possible. Technical data for control mode Differential pressure p v0 : <5 kpa (may not be exceeded) Differential pressure p v @ 54 : The values listed in the Differential Pressure Table must be complied with Valve authority: >0,3 Rangeability: >30 The S-shaped characteristic curve of the D6..N(L) butterfly valve (BFV) does not correspond to the equal percentage characteristic curve pursuant to VDI 176. It is only in the angle of rotation range between 0 and 54 that one can speak of an approximately equal percentage characteristic curve. For an opening angle of 54, the k vs corresponds to approx. 35 percent of the k v max value for a 90 opening angle. S-shaped characteristic curve k v / k v max 100% S-shaped characteristic curve e.g. D650N Flow rate 50% Theoretically equal-percentage characteristic curve k vs 35% S-shaped characteristic curve e.g. D6300N Definitions k v max und k vs The flow rate of k v max will ensue when the disc is fully open (90 ). The k vs value refers to the flow rate at 54 opening angle, 1 bar pressure loss and medium temperature: 5 C... 40 C. 0% 0 18 36 54 7 90 Opening angle Scaled characteristic curve range k v / k vs Deviation >10% 100% 10% 0% 10% Deviation >10% 0% 0% 100% 54 The k vs @ 54 listed in the differential pressure table deviates from the usual tolerance (±10%) for some nominal widths. The equivalence factor of the equal percentage characteristic curve is ~.5. 6 / 8 P5-Shut-off and butterfly valves en v.0 09.010 Subject to changes www.belimo.com
Butterfly valves for control mode Design and dimensioning (Continued) Because of this fact, there is no configuration option available with the modulating actuators of limiting the angle of rotation range from 0 to 54. The angle of rotation range required can be adjusted accordingly afterwards with the F and P types using the PC-Tool FT-P, Version 3.3. The differential pressure p v @ 54 (arked in grey in the table «Flow rate») may not be exceeded. This will ensure that the maximum permissible medium speed of 4 m/s is maintained. Depending on the nominal width, the closing angle lies between 7 and 16. Formula The effective volumetric flow calculated for opening angle α is: @ α = k vs @ α 100 @ α k vs @ α p @ α p v @ α 100 Flow rate Closing pressure Definition p s Closing pressure at which the actuator can still seal the valve tightly allowing for the appropriate leakage rate.
