SPECIFICHE TECNICHE

V1810YAlwa-Kombi-4

Valvola per acqua calda sanitaria

Applicazione

La valvola Alwa-Kombi-4 è una valvola per il bilanciamento idronico degli impianti di distribuzione di acqua calda potabile.Il bilanciamento idronico si ottiene regolando la portata di distribuzione mediante la preimpostazione manuale della valvola. La valvola può essere dotata anche di attuatore termico, per la regolazione precisa della temperatura dell’acqua nell’impianto di distribuzione. L’attuatore termico può essere installato senza interruzione dell’erogazione di acqua calda.Quando si utilizza l’attuatore termico 50-60 °C è supportata la disinfezione termica in conformità ai worksheet DVGW W551 e W553. Il bilanciamento idronico, inoltre, viene mantenuto durante il processo di disinfezione termica per garantire la disinfezione di tutte le tubazioni di distribuzione.

V1810Alwa-Kombi-4

Circulation throttle valveProduct specification sheet

Alwa-Kombi-4 with internal threads

Construction

The Alwa-Kombi-4 valve consists of:

• Valve housing in straight pattern with internal threads to ISO 7 (DIN 2999) or external threads according to DIN ISO 228

• Valve insert

• Handwheel with digital display of pre-setting

• Thermal actuator (accessory)

• Pipe connections (accessory)

Materials

• Valve housing made of red bronze

• Valve insert made of red bronze and brass

• EPDM O-rings

• PTFE seat sealing

• Handwheel, pre-setting dial and display made of plastic, orange

Application

The Alwa-Kombi-4 is used as throttle valve for hydronic balancing of warm potable water circulation systems.

To achieve a hydronic balance the flow in the circulation pipe is throttled by manually pre-setting the valve. The valve can also be equipped with a thermal actuator which allows a regulation of the water temperature in the circulation system to the exact degree. The thermal actuator can be installed without interruption of the warm water supply.

When the thermal actuator 50 - 60 °C (122 - 140 °F) is used, a thermal disinfection according to DVGW worksheet W551 and W553 is supported. Hydronic balance is also retained during the thermal disinfection process to ensure disinfection of all pipelines and risers.

Special Features

• Meets KTW requirements

• For regulation according to DVGW worksheets W551 and W553

• Valve housing and all parts with flow-contact made of corro-sion-resistant red bronze

• Retrofittable automatic temperature-control with support of thermal disinfection

• Draining option with retrofittable and removable draining adapter

• No additional side connections to valve housing

• Cavity-free cartridge with maintenance-free spindle sealing

• Spindle thread is isolated from the flow

• Seat sealing made of PTFE

• Visible, digital pre-setting dial with concealed pre-setting handwheel

• High accuracy due to factory calibration to every single valve

FunzionamentoLa valvola Alwa-Kombi-4 regola la portata nelle tubazioni di distribuzione. L’effetto viene ottenuto chiudendo la valvola manualmente in una determinata posizione oppure automaticamente, se la valvola è dotata di attuatore termico.

Preimpostazione manuale: la valvola è preimpostata in base al valore calcolato e rimane in tale posizione. Ilflussodell’acquaèlimitatodallariduzionedell’aperturadella valvola.

Regolazione automatica: la valvola è dotata di attuatore termico ed è preimpostata alla temperatura dell’acqua desiderata. L’attuatore termico mantiene con precisione la temperatura nella valvola.Quando la temperatura dell’acqua scende, la valvola si apre eilflussodiacquacaldaaumenta.Quando la temperatura dell’acqua aumenta, la valvola si chiude e si esclude quando viene raggiunta la temperatura dell’acquapreimpostata(adeccezionedellapercentualediperdita).

Con la preimpostazione manuale, la valvola può essere impostata solo per il funzionamento ottimale a pieno carico. Il processo di regolazione automatica consente la regolazione permanente e un’erogazione ottimale in tutte le tubazioniconlamassimaefficienzaenergetica.

Come tutte le valvole della famiglia Honeywell “Kombi“, la valvola può essere dotata di ulteriori funzioni anche dopo l’installazione.

Tali funzioni vengono applicate con l’installazione di appositi adattatori nell’alberino della cartuccia:

• L’attuatoretermico(preferibilmente50-60°C)puòessereinstallato in qualunque momento senza interrompere l’erogazione dell’acqua calda. L’attuatore viene semplicemente avvitato all’inserto e consente il bilanciamento idronico permanente in base alla temperatura dell’acqua nel tubo di distribuzione.

• L’adattatorediscaricosiapplicaperfardefluirel’acquaepuò essere rimosso al termine del processo di scarico. Può essere utilizzato con qualunque valvola di bilanciamento per acqua potabile Alwa-Kombi-4 e anche con la valvola di bilanciamento del riscaldamento e del raffreddamento Honeywell Kombi-3-plus.

• La temperatura corrente nella linea di distribuzione può essere letta sul termometro in qualunque momento. Il termometro può essere utilizzato con o senza attuatore controllato dalla temperatura.

• La valvola di campionamento è utilizzata assieme all’adattatore di scarico e determina i parametri chimici e microbici.

Disinfezione termica a temperature superiori a 70 °C

Supportata dalla valvola Alwa-Kombi-4 se dotata di attuatore termico 50-60 °C.A partire dalla percentuale di perdita, la valvola si apre quando la temperatura dell’acqua raggiunge 63 °C e la portata aumenta.

Quandolatemperaturadell’acquaraggiunge72°C,ilflussoviene ridotto a una portata inferiore alla percentuale di perdita.In tal modo, il bilanciamento idronico viene mantenuto e l’acqua calda viene distribuita rapidamente in tutte le tubazioni e le montanti.

Quando il processo di disinfezione termica termina e la temperatura diminuisce nuovamente, la valvola Alwa-Kombi-4 torna nella posizione di controllo standard.

kvs-value of Alwa-Kombi-4 with installed thermal actuator50 - 60 °C (122 - 140 °F) in relation to water temperature atpre-setting 1.5

Pre-setting values for thermal actuators

We recommend:Pre-setting value =desired minimal temperature

(standard setting)

Desired minimal temperature55 °C (131 °F) = Pre-setting 1.5

If the required throttle position according to DVGW worksheet W553 is to the right of the 2K-line (tempreature in pipe is below 53°C [127°F] at pre-setting 1.5) the pre-setting has to be increased by 2K:

Desired minimal temperature55 °C (131 °F) + 2K = Pre-setting 1.7

If the required throttle position according to W553 is to the right of the 5K-line (temperature in pipe is below 53 °C [127 °F] at pre-setting 1.7) the following possibilities are left:

• Manually pre-set thermal actuator and valve with values calculated according to DVGW worksheet W553.

• Use valve of larger dimension.

• Increase pre-setting by 5K:55 °C (131 °F) + 5K = pre-setting 2.0The increased pressure loss over the valve must be taken into account when the pump is specified!

When installation is set according to above recommendations the hydronic balance is also retained at 70 °C (158 °F) - during the thermal disinfection process.

Valori di preimpostazione per attuatori termici

Si raccomanda:

• Valore preimpostazione = temperatura minima desiderata (impostazionestandard)

• Temperatura minima desiderata 55 °C = preimpostazione 1,5

Se la posizione richiesta della farfalla, in accordo al worksheet DVGW W553, è a destra della linea 2K (temperaturaneltuboinferiorea53°Cconpreimpostazione1,5), la preimpostazione deve essere aumentata di 2K:

• Temperatura minima desiderata

• 55 °C + 2K = preimpostazione 1,7

Se la posizione richiesta della farfalla, in accordo al worksheet DVGW W553, è a destra della linea 5K (temperaturaneltuboinferiorea53°C,conpreimpostazione1,7), la preimpostazione deve essere aumentata di 2K:

• Preimpostare manualmente l’attuatore e la valvola con i valori calcolati in base al worksheet DVGW W553

• Utilizzare una valvola di taglia superiore

• Aumentare la preimpostazione di 5K: 55 °C + 5K = preimpostazione 2,0

Quando l’installazione viene effettuata in conformità alle raccomandazioni sopra indicate, anche il bilanciamento idronico viene mantenuto a 70 °C durante il processo di disinfezione termica.
