Water, digester gas, and biogas applications

 

As one of Sweden’s leading suppliers of valves and instruments, we offer a wide range of products and qualified technical support for water, digester gas, and biogas applications. We supply everything from individual components to complete valve packages for both small and large water infrastructure projects across the country. Don’t hesitate to contact us if you’d like to discuss technical solutions or request a quote for upcoming investments.

Products approved for drinking water applications

We offer several products that are certified for use in drinking water systems. For example, we provide products with WRAS-approved EPDM, epoxy coatings approved under French ACS standards, and components certified by the German DVGW.

Read more below about the different materials and certifications.

WRAS-approved EPDM

We offer a variety of products containing EPDM (ethylene propylene diene monomer rubber), a synthetic rubber material known for its excellent resistance to heat, ozone, and aging. Thanks to these properties, EPDM is well-suited for use in water systems, including those for potable water.

Our EPDM products are WRAS-approved (Water Regulations Advisory Scheme), which means the material has been tested and meets UK requirements to ensure it does not affect water quality or pose any health risks. A WRAS approval is a recognized assurance that the material is safe for contact with drinking water.

ACS-approved epoxy

We offer several products with epoxy coatings, particularly for applications requiring a durable and corrosion-resistant surface that is also safe for drinking water contact. The epoxy coating provides effective protection against chemicals, wear, and rust.

The epoxy we supply is certified for drinking water use under the French ACS (Attestation de Conformité Sanitaire) standard. This means the material has been tested and approved to ensure it does not compromise the quality or safety of drinking water. ACS certification is a requirement in France and a recognized indicator of suitability for use in potable water systems.

DVGW-certified for drinking water

We provide products that meet the stringent requirements for DVGW (Deutscher Verein des Gas- und Wasserfaches) certification for drinking water systems. This means the products have been tested and approved for use in potable water systems without affecting water quality or safety.

DVGW certification includes both hygienic and technical standards, ensuring that materials do not release harmful substances and that components are designed for long-term use in drinking water installations. It is a widely recognized standard in Germany and across the EU, and serves as a reliable assurance that a product is safe for use in drinking water applications.
