Function
In the simple shut-off, there is only one seal in the one piece valve disc separating the pipelines from one another. This means liquid can pass from one pipeline to the other in the eventuality of a seal defect. For this reason, single-seat shut-off valves are not suitable for separating incompatible products.
Special Features
- Certified, hygienic configuration
- Metallic stop
- Flexibility because of the modular principle
- Proven seal geometry
The ECOVENT® valve series is characterized by its compact design.
| Single-seat shut-off valves |
| DN 10 – DN 100 |
| OD 1" – OD 4" |
| Recommended Flow Direction | Feature | Type |
| from Bottom to Top | Compact Design | Single-seat Valve, Type N/ECO |
| from Bottom to Top | Small Nominal Width
DN 10 or DN 15 | Single-seat Valve, Type N/ECO small |
Application Examples
In practical use, these valves are used
- as emptying / drainage valves
- for shutting off a bypass line
- as dosing valves
The ECOVENT® small valve type N / ECO in nominal widths DN 10 or DN 15 is predominantly used as a feed valve for supplying the spray cleaning of double-seat valves.

GEA Insights
The breakthrough that changed spray drying
In 1976, NIRO engineers responded to a competitive challenge by rethinking what spray drying could do. Their idea became the multi-stage dryer MSD. Fifty years later, the same fundamental principle helps turn liquids into the powders used in essential nutrition products and important medicines around the world. Refined through decades of engineering expertise, customer insight and continuous development, MSD is a story of innovation with lasting impact.
Beyond the machine: unlocking better plant performance
An efficient machine does not automatically make an efficient factory. Real improvement often starts by looking beyond individual equipment and understanding how processes, energy systems and operating decisions affect one another. It’s a holistic approach designed to uncover opportunities that might otherwise be missed.
How a valve reshapes the way food and drinks are made
In food and beverage plants, valves are commonly operated using compressed air. GEA Hydract® Actuation Technology moves valves with water instead, in a closed, digitally controlled circuit. The result is a valve that can be held exactly in place and steered in fine-tuned steps. This results in lower energy use and greater control.
