DELTA UF3 Model
DELTA UFR3 with modeling cone to maintain constant pressure
Possible application
An example of pump protection in production.
- Discharge pump
- DELTA UFE34 with CIP saddle lift
- Pump suction line (low pressure)
- Direction to the processing line (high pressure)
Advantages
- Optimum cleanability due to Ball-shaped housing without sump or dome. No dead spaces in the valve body.
- No stroke limitation by seat lift actuator; the full opening cross section is available during cleaning.
- Very easy to service - only four screws must be released and the valve insert can be lifted out
- 3-A approved, comply with ATEX
- In addition, all valves can be provided with a seal lifter, e.g. to relieve pressure during cleaning operations. High pressure version is available on request.
