Discharge valve for liq. products

摘要

The valve has an actuator (32), a product duct (30) and a sterilisation or ringing duct (20), coupled to the product duct in one valve position, and a product valve (26) stopping the product duct. A sterilisation valve (28) between the product and sterilisation ducts is controlled by the valve actuator. Pref. the valve actuator automatically stops the product valve prior to opening the sterilisation valve. It automatically opens the latter on stopping the product valve. Typically the sterilisation valve directly opens into the product passing section of the product duct, pref. near the product valve.
