Santon ALK01 Expansion Vessel Kit for Aqualine

Aqualine ALK01 accessory kit. Expansion vessel, expansion relief valve, pressure reducer / strainer & non-return valve.

For all situations where the mains pressure is greater than 4.1 bar. The pressure reducing valve reduces incoming pressure to 3.5 bar while the strainer filters coarse impurities from the incoming water. The expansion valve acts as a backup to the expansion vessel, opening at 6 bar. The non-return valve prevents back-flow of hot water which could cause cross-contamination of the inlet water. The pressure reducing valve must be installed on the mains side of the expansion vessel. For balanced hot/cold water supplies, the pack should be fitted on the mains side of the cold water draw off; this is particularly important where mixers are used.
