Single-seat Valves
ECOVENT® Shut-off valves
ECOVENT® single-seat valves are used for simple shut-off in hygienic applications. The valves are characterized by their ease of operation and flexibility.
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.
