Thanks to ongoing enhancements to this product range, its area of use has continued to grow in recent years. With immediate effect, in addition to the existing DVGW approval for water, this series will also have the certificate for gas.
Equipment that has been tested in accordance with DVGW's regulatory code is guaranteed to comply with the applicable regulatory codes and standards and to meet high quality guidelines.
This means that it is now possible to use the GEMÜ 481, GEMÜ 487 and GEMÜ 488 butterfly valves for applications that demand DVGW gas approval. Examples of this include gas production, treatment and injection. Depending on the product type, the butterfly valves are available with the new approval in versions that have manual, pneumatic or motorized actuators.
