Pentair Südmo Double Seal Valve SD Economic
Pentair Südmo Double Seal Valve SD Economic is an cost effective yet technologically-sophisticated alternative to liftable and balanced mixproof double seat valves.
The design of the SD Economic is based on many years of experience in valve construction and production. Pentair Südmo’s SD Economic is an cost effective yet technologically-sophisticated alternative to liftable and balanced double-seat valves.
SD stands for single-disc Seat valve with Double seal functionality. With this type of valve, two incompatible media (e.g. CIP and product) can be separated in the pipelines without mixing. This is ensured by two separate seals, between which an open air space enables any potential leaks to be detected and removed. Additionally, the leakage chamber can be externally flushed by two valves fitted on each side.
Product Description
Valve position “Closed”
- Two incompatible media are separated without mixing (e.g. CIP and product)
- Flush/leakage valves open with spring force
- Any potential leaks are detected and removed
Valve position “Open”
- Upper and lower lines connected
- Flush/leakage valve closed with air pressure
- Recommended direction of flow during closing procedure (see arrows)
Flushing of the leakage chamber
- 180° offset positioning of flush valve prevents cleaning shadows
Sterilization
- Sterilization of seat area over flush valve
- Sterilization of stem area with optional sterile chamber
Innovative Sealing Solution: SAFE – DURABLE – EASY MAINTENANCE
1. RSC (Radial Seal Complete) seal as radial sealing element
- Small contact area (optimized friction characteristics)
- Very good swelling compensation
2. O-ring as axial sealing element
- Metallic stop to protect against excessive stress
3. PEEK as sealing of leakage outlet
- Sealing close to product area
