IMP Armature>Non-return valves

Non-return valves

They are distinguished by a series of exceptional features and quality. We manufacture flanged swing check valves, diaphragm valves and wafer swing check valves in various designs and adjustments.

Non-return valves enable complete and quick closing of the return flow in pipelines. The simple construction allows for easy handling and maintenance and a long service life. Microbiological suitability is guaranteed by EPDM seals and Epoxy powder protection, as supported by relevant certificates.

We also offer appropriate additional equipment. With the added weight, the backflow arrester is even faster. Their use can be upgraded by a lifting valve and manometer connections.
