Sanitary Pneumatic Tank Bottom Valve
This sanitary pneumatic tank bottom valve is specifically designed for direct installation at the bottom of process tanks, providing automated shut-off, discharge, and sampling control. The Y-shaped body eliminates dead zones, ensuring complete tank drainage and preventing media residue. Constructed from high-grade stainless steel with hygienic seals, it meets the strict standards of food, beverage, pharmaceutical and biotech industries, enabling reliable, contamination-free process control.
Sanitary Pneumatic Tank Bottom Valve
Key Features
- Zero-Dead-Zone Drainage: Optimized Y-shaped body design eliminates dead corners, allowing full tank emptying and preventing media buildup or bacterial growth.
- Pneumatic Actuation: Equipped with a stainless steel pneumatic actuator for fast, automated opening/closing, suitable for remote control and automated production lines.
- Hygienic Construction: 304/316L stainless steel body with polished, crevice-free surfaces, fully compatible with CIP/SIP cleaning processes.
- Food-Grade Sealing: Sanitary diaphragm seal (EPDM/PTFE optional) provides leak-tight sealing, isolating the media from the actuator to prevent contamination.
- Easy Installation & Maintenance: Flange-style tank bottom connection for direct mounting; modular design allows quick disassembly for cleaning and maintenance.
