The QL8 is a single lever thermostatic faucet/mixer cartridge that blends hot water with cold water to ensure a constant, safe outlet temperature that maximises comfort levels and prevents scalding during periods of dramatic input temperature or pressure variation. Used in conjunction with the PEV (pressure equalisation valve) and/or the PBV (pressure balance valve) this product is designed to meet global certification standards. The benefits of the QL8 thermostatic cartridge design are: �Allows the storage of water at high temperatures or instant hot water heating to high temperatures thus removing the breeding ground for bacteria such as Legionella �Has, in conjunction with PBS, hot and cold water failure shutoff capability designed to prevent thermal shock or scalding � Ensures water is delivered to a shower and/or faucet at the required temperature at or below a factory preset maximum irrespective of the input water temperature or pressure �Will meet new certification requirements for water temperature safety and certification in markets where central authorities are now regulating safety and is ideal for residences, public facilities, hotels, retirement homes and hospital use. �Reduces hot water consumption by preventing waste of excessively hot water at the faucet and/or mixer and may reduce the need for excessively hot water storage facilities.
