Detailed Description
Inflatable Seal Spherical Valve – Optimized Solution for Hygienic Discharge from Cone-Bottom Vessels
The Inflatable Seal Spherical Valve is engineered for high-performance, hygienic discharge applications from conical hoppers or vessels. Its unique spherical outlet structure, combined with advanced inflatable sealing technology, ensures excellent containment, easy cleaning, and reliable material flow control. The valve is adaptable to various process conditions through optional configurations including bottom drainage, clean gas purge, and tool-free CIP support.
Key Features & Advantages:
Efficiently drains residual liquids from the vessel bottom during processing or cleaning. Optional mesh filter screens are available to meet different process needs.
Allows connection to clean gas lines for purging and drying residual or sticky materials near the discharge zone—ideal for preventing buildup and improving discharge consistency.
Provides zero-friction, zero-particle-release sealing with exceptional tightness. This non-invasive sealing system reduces wear and ensures extended valve life, especially suitable for sterile and high-purity environments.
Constructed with sanitary-grade components and smooth internal surfaces to meet stringent hygienic standards. Supports CIP (Clean-in-Place) cleaning without disassembly, ensuring fast turnaround and minimal contamination risk.
The valve is suitable for liquids, powders, granules, and slurries, making it a flexible and reliable choice for the pharmaceutical, biotech, food, and fine chemical industries.
