When it comes to rotary and diverter valves, compliance with international standards and certifications isn't just a formality. It is a critical part of ensuring safety, performance, and market acceptance. Whether operating in explosive atmospheres, hygienic environments, or demanding industrial settings, these components must meet stringent regulations. This page provides an overview of the key labels and certifications that apply to Coperion rotary and diverter valves, helping you understand what each one means and why it matters for your application.
Standards, Certificates & Labels of Coperion Components
Certificates and Labels
ATEX
ATEX regulations are essential for ensuring safety in explosive atmospheres within the EU. They consist of two key directives: Directive 2014/34/EU, which covers equipment and protective systems intended for use in potentially explosive environments, and Directive 1999/92/EC, which focuses on the responsibilities of employers to maintain safe working conditions in such areas. Together, these directives help reduce the risk of ignition in hazardous zones by setting clear requirements for both equipment design and workplace safety practices. Compliance with ATEX standards is not only a legal obligation but also a crucial step toward protecting workers and facilities.
CE
CE refers to a crucial declaration that equipment and systems meet EU standards for safety, health, and environmental protection. This includes compliance with directives such as the Machinery Directive, the Pressure Equipment Directive, and ATEX Directive 2014/34/EU when used in explosive atmospheres. For manufacturers and operators in sectors like chemical processing, oil and gas, or pharmaceuticals, CE marking ensures that process equipment, such as rotary or diverter valves, is safe to operate and legally permitted for use within the European Economic Area.
EHEDG
EHEDG (European Hygienic Engineering & Design Group) plays an important role in promoting hygienic design and engineering. EHEDG certification ensures that equipment is designed for easy cleaning and minimizes the risk of contamination, supporting compliance with strict hygiene and food safety regulations. Components like rotary or diverter valves, that carry the EHEDG mark have been tested to meet rigorous standards for cleanability and microbial safety. For manufacturers, using EHEDG-certified equipment not only helps meet regulatory requirements but also ensures product quality and consumer protection in hygienically sensitive processes.
USDA
USDA is a certification for food and pharmaceutical applications (specifically from the USDA’s Agricultural Marketing Service). It certifies that the equipment meets the sanitary design standards required for use in federally inspected facilities in the United States. This includes requirements for materials, construction, and cleanability to prevent contamination and ensure food safety. USDA-compliant equipment, which also includes rotary or diverter valves, is typically made with non-toxic, corrosion-resistant materials and designed to allow thorough cleaning and inspection. For manufacturers and processors exporting to or operating in the U.S. market, USDA approval is a key indicator of hygienic design and regulatory compliance in food-grade processing environments.
