HYGIENIC VALVE PRODUCTS

Valves & components for hygienic liquid processing

Product Overview

Hygienic valves have been manufactured by GEA for over 80 years. They are the core component in matrix-piped process plants and contribute significantly to the highest product quality. With our range of valves we provide the market with solutions for highly complex tasks as well as for basic functions. Our valves are economically designed for the application they are intended for.

Benefits

  • The design of the valves and individual components without dead space satisfies the most exacting hygienic requirements and prevents unnecessary product losses.

  • Thanks to the metallic stops, the seals used are characterized by a very long service life. This significantly cuts operating costs.

FLANGE CONNECTIONS & FITTINGS

The valve housings can be specified with a welded-on or other connection fitting.

If the vertical ports within a valve have different configurations, there are different connection fittings. The seal which may be included corresponds to the sealing material of the valve.

PRODUCT RECOVERY SYSTEMS

Cleaning of process lines is always an issue – both to meet the strictest criteria for hygienic design both also to gain as much product out of the pipes as possible. The answer to both cleaning and maximum output is a Product Recovery System.
