Reliable butterfly valves from NieRuf

Within closed pipeline systems, different and sometimes aggressive media have to be controlled and operated reliably. Shut-off valves from NieRuf Industrial Valves play a crucial role in a closed pipeline system and ensure that your facility operates reliably. Butterfly valves can be used to stop the flow rate entirely, thereby preventing damage to the facility. But they also play a crucial role in maintaining proper operation. Since the flow rate varies depending on the pipeline system you are using, we offer butterfly valves with different denominations from DN25 to DN400.

Double-eccentric butterfly valves  DN50 to DN400 - with hand lever, gearbox or automated

Double-eccentric butterfly valves provide precise and reliable shut-off solutions for demanding industrial applications. Thanks to their special design with double-eccentric discs, they minimize contact between the seal and the disc, resulting in a longer service life and higher efficiency. These valves are ideal for use in the oil and gas, chemical, and water and wastewater industries. They provide excellent sealing performance even at high pressures and temperatures. We supply double-eccentric butterfly valves in nominal diameters of DN50 to DN400 and offer various actuation options, including hand levers, gearboxes or automated actuators (electric or pneumatic), depending on your individual requirements.
