Qual è la differenza tra una valvola di erogazione manuale e una automatica?

Manuale: rimane aperta finché si preme la leva – l'utente deve chiuderla da sé. Automatica: si chiude da sola tramite un sensore di depressione quando il serbatoio è pieno – impedisce il sovrariempimento e gli schizzi di ritorno. Particolarmente importante per i piccoli serbatoi SCR delle auto.

Perché mi serve una valvola di erogazione specifica per l'AdBlue?

L'AdBlue corrode rame, zinco, ottone e alluminio. Le valvole di erogazione per AdBlue sono in PP, PVDF o acciaio inox. Non utilizzare una pistola per gasolio per l'AdBlue – la contaminazione dei materiali danneggia in modo permanente il sistema SCR.

Quale portata mi serve per la mia valvola di erogazione?

Auto/furgoni (serbatoio SCR 5–25L): max. 10–20 l/min – la Elaflex LV 4AF.0 F è limitata specificamente a 10 l/min. Camion (40–100L): fino a 40 l/min (Elaflex HV 4M.0 F). PIUSI SB325 e HORN A2003-KS per la fascia media di 20–45 l/min.

Cosa significa A2003-KS o SB325?

A2003-KS (HORN): serie automatica, KS=plastica, uscita 19mm – la valvola standard per impianti HORNET. A2003-ES: versione in acciaio inox. SB325 (PIUSI): valvola automatica della linea Suzzarablue, 3/4". ZVA (Elaflex): HV=Heavy Vehicle (camion), LV=Light Vehicle (auto).

Manual – simple & low-cost

PIUSI manual dispensing valve (€79.94, 80 l/min) and HORN plastic dispensing valve (€119.50) with a swivel joint – for the simple dispensing of AdBlue® from drums and IBC containers without an automatic shut-off. For operations that dose manually and control the quantity themselves.

Automatic – with shut-off

The HORN A2003-KS (€215) and PIUSI SB325 (€282) shut off automatically when the tank is full – preventing overfilling and AdBlue® splash-back. All made of AdBlue®-resistant plastic (PP/PVDF), with a swivel joint for comfortable refuelling.

Stainless steel & with a meter

The A60 INOX automatic dispensing valve (€364) made of stainless steel with a swivel joint for a particularly corrosion-resistant version. The PIUSI SB325M + meter (€436) with an integrated digital meter for a direct quantity display without a separate flow meter – practical for internal operational consumption recording.

Truck & car-specific

The Elaflex ZVA HV 4M.0 F (€660) for truck refuelling – 40 l/min, a 1" stainless-steel connection, for large SCR tanks. The Elaflex ZVA LV 4AF.0 F (€670) specifically for cars – max. 10 l/min, preventing the overfilling of small SCR tanks. Both for professional stationary dispensing points.
