Sanitary Tri Clamp Ball Valve for VDF
This is a 1-inch 304 stainless steel sanitary tri clamp ball balve designed for VDF. Its wetted parts feature a mirror-polished finish with no dead corners or residue buildup, complying with GMP/FDA hygiene standards for the food and pharmaceutical industries.
It comes with a manual lever design (pneumatic/electric actuation upgrades available); a 90° rotation is all it takes to open or close the valve, making it ideal for the frequent-operation demands of filtration processes.
Constructed from 304 stainless steel paired with high-quality seals, it offers a service life of over 100,000 opening/closing cycles—perfect for the long-term, stable operation of vacuum drum filters.
- Body Material: Valve body, ball, and stem are all made of 304 stainless steel (suitable for both food-grade and industrial applications; 316L is available for high-end scenarios)
- Connection Type: Clamp-type (TC-style), allowing tool-free quick assembly and disassembly—ideal for pipeline maintenance of vacuum drum filters

core function
- Fluid On/Off Control: A 90° rotation of the lever enables quick opening/closing of the filter’s feed/discharge pipelines. It aligns precisely with the drum’s rotation cycle, ensuring stable control of material flow.
- Vacuum Pressure Retention: When closed, it provides a high-seal performance for the pipeline (typically with a leak rate ≤ 1.3×10⁻⁴Pa·L/s), preventing external air infiltration that would disrupt the filter’s negative pressure environment and ensuring filtration efficiency.
- Cleaning CompatibilityIts clamp-type design and dead-corner-free structure allow easy disassembly for cleaning (supports CIP in-place cleaning), meeting the periodic cleaning requirements of vacuum drum filters.
- Material Backwash Assistance: After a filtration cycle, vacuum drum filters require filter cloth backwashing (to remove filter cakes). This ball valve can quickly switch the pipeline flow direction, coordinate with the introduction of backwash media (e.g., clean water, compressed air), assist in efficient filter cloth cleaning, and quickly restore the filtration pipeline via its clamp-type design—reducing equipment downtime.
