Valves for applications with product contact
Our sterile valves with EHEDG certification or 3A conformity are designed to handle demanding applications with product contact, making them ideal for use in food and beverage production. Our FDA-compliant pinch valves are equally suitable for handling products with high viscosity or mixed products that require gentle handling. These valves are used in brewing beer, manufacturing soft drinks, coffee, wine, milk, yogurt with fillings, dense and liquid chocolate, cooking sauces, and condiments.
Valves for bottling processes
Valves from Schubert & Salzer are also used in the bottling of beverages and food. Seat valves and sliding gate valves are used for dosing different process gases and regulating tank pressure, or flow rates. Our angle seat valves in hygienic versions meet the requirements of the EC regulation 1935/2004 and are ideally suited for KEG cleaning and bottling plants in the beverage industry. Aseptic valves in two-way stop design, provide a cleaner alternative to typical stem seal single seat products.
Valves for CIP and SIP processes
Regular cleaning processes (CIP/SIP) are undertaken to prevent contamination of the product during product changes or the effect of bacteria and microorganisms during stoppages. Plants in the food industry and the valves installed in them undergo these cleaning processes. With valves from Schubert & Salzer, the cleaning media is tempered and fed to the plants. Sterilization with steam is performed for strict requirements or complete plants are kept free of bacteria with sterile air.
Valves for heating and cooling processes
Valves from Schubert & Salzer are used to shut off, vent, and regulate operating media such as steam and hot air, as well as heating and cooling water. These are used in cooking and chilling, autoclaves, retorts, or pasteurization. In the food and beverage industry, these valves are used in vessels for the manufacture of preserves, canned cocktails, hard seltzers, and beer, tempering of chocolates, refining of edible oils, potato peeling, fryers of snack foods and specialty potatoes, freeze-drying of fruits, spray drying of milk products, and hot and cold smoking plants for meat and fish.
Valves for auxiliary media
Schubert & Salzer's valves are commonly used for auxiliary media in the food and beverage industry, such as water, air, CO2, or nitrogen. Sliding gate valves are particularly useful for very high or low temperatures, high pressures, or when fast switching processes, high control accuracy, or rangeability are required. Angle seat valves are ideal for small nominal sizes and low operating pressures where high leak tightness is necessary. Ball sector valves are suitable for pure auxiliary media like brewing or drinking water, as well as for gases and liquids that safely transport the product.
Most valves in Schubert & Salzer's range comply with EC regulation 1935/2004, and the elastomers used are FDA-compliant.
Valves for explosion-proof areas
In various applications such as the distillation of alcohol and the granulation of flour, strict regulations have been put in place to ensure explosion protection. Schubert & Salzer offers shut-off and control valves that are compliant with ATEX 2014/34/EU regulations, making them suitable for use in these areas. Additionally, these devices can be used in areas that require FM approvals according to non-incendive field wiring Class I Division 2 or intrinsic safety field wiring Class I, Division I.
