Advantages
The glass-lined steel construction of CleanValve ensures zero metal contamination, making it ideal for hygienic and high-purity applications across a wide temperature and pressure range. Designed for rigorous cleaning operations, it features:
- Optimized Cleanability: A 5º downward-sloping port facilitates efficient internal cleaning, preventing residue buildup.
- Patented Flat Seat Design: Eliminates material accumulation in the annular space between the valve seat and nozzle wall.
- Retractable Spray Nozzle System: Enhances cleaning efficiency without process interruption.
- Accurate Temperature Measurement: Accommodates temperature sensors and measurement electrodes at the vessel’s lowest point for precise, reliable readings.
- High Corrosion Resistance: Made from cast steel with DD3009 glass enamel, identical to De Dietrich reactors, ensuring durability against corrosion, thermal, and mechanical shocks. Wetted parts include fluoropolymer (PTFE, PFA) coatings for enhanced protection.
CleanValve guarantees superior process safety, cleanability, and reliability, making it the optimal bottom outlet valve for demanding pharmaceutical, chemical, and food-processing applications.
