Non-return valvesOne way, without fussGuth non-return valves protect and secure against unwanted backflow - precisely and fast Guth non-return valves in the online product catalogue |
The plate non-return valves from Guth secure pipelines against an unwanted liquid return flow.
The spring-loaded fitting is characterised by a precise response and a reliable seal. Here, it is designed with optimised flow in mind and prevents turbulence in the direction of flow. For small pipe diameters, there are compact designs in the nominal diameters DN 10 and DN 15.
• hygienic seal, similar to DIN 11864
• flow-optimised housing
• minimum number of seals
• no corners/dead spaces
• flow-optimised plates
