Multi-purpose AV 23 SETTER SD flow measuring and setting valve from TACOTHERM LTD is ideal for controlling water & glycol flow rates in Heat Pump applications. Typical systems include ground source heat pumps and air to water heat pumps where an accurate flow rate will optimise the heat pumps COP (coefficient of performance).
The valve provides flow regulation, isolation facility and easy to read flow measurement via the sight glass and a user-friendly setting scale, Designed for domestic, commercial and public sector applications, the AV 23 SETTER valve allows accurate and fast balancing without diagrams, tables or the need for costly measuring devices.
Systems which are correctly balanced and air-free guarantee optimal energy extraction and are therefore more cost effective. TACOTHERM’s AV23 SETTER range is designed specifically for ‘ease of use’ and ensures that that the energy savings gained through using heat pumps are not compromised by system inefficiency.
The AV23 SETTER is also user friendly. Engineers can set the appropriate flow rate using the unique flow measurement device, avoiding investments in training and costly measuring devices. The valve also has a setting scale and allows direct reading of the adjusted flow rate at the sight glass. These features result in an accurate measurement of the optimal flow range.
The valve’s flow measurement is based on the principle of a baffle float with return spring, where the measurement is read on the bottom line of the float. Meanwhile, the measuring device is placed in a bypass, isolated from the system flow. Through demand, the bypass is opened and closed through pressing and releasing the valve handle. However, an advantage of TACOTHERM’s AV23 SETTER is that reading the flow has no influence on the main flow rate, eliminating the need for an additional shut-off device.
Other advantages of the TACOTHERM AV23 SETTER valve includes its flexibility and ease of installation since it can be fitted horizontally, vertically or in an inclined position cutting installation time. Further time savings can also be made since it is possible to replace the bypass unit without emptying the system.
