Description
Tank mounted flush bottom ball valves are specialized industrial valves designed for efficient and complete discharge of media from reactors, tanks, vessels and containers. These valves feature a unique surface-engineered inlet flange that allows direct welding and flush mounting at the lowest point of process equipment. The smooth tapered bore and ultra-short distance between the valve ball and tank bottom eliminate media accumulation at the entrance, ensuring smooth and complete discharge of even viscous or solid-laden fluids.
Our flush bottom ball valves are engineered with an ISO 5211 direct mounting platform, enabling straightforward actuator installation without the need for additional mounting brackets. This design reduces installation time and minimizes potential leak points. Manufactured to the highest international standards, these valves deliver reliable performance in demanding industrial environments where product purity and process efficiency are critical.

The flush bottom ball valve operates on the quarter-turn principle, where a hollow ball with a through bore rotates 90 degrees to control fluid flow. When the valve is open, the bore aligns perfectly with the tank outlet, creating an unobstructed flow path. When closed, the ball rotates to block the flow completely.
The unique flush-mounted design positions the valve body directly at the tank bottom, eliminating any dead space where media could accumulate. The smooth tapered inlet ensures that even viscous materials, slurries or products with solid particles flow freely without getting trapped. This design prevents cross-contamination between batches and simplifies cleaning procedures, making these valves ideal for hygienic applications.
The most significant advantage of our flush bottom ball valves is their zero dead space configuration. The valve ball sits extremely close to the tank bottom, and the smooth tapered bore ensures complete drainage of process media. This eliminates product waste, reduces cleaning time, and prevents bacterial growth in hygienic applications.
All our flush bottom ball valves come standard with an ISO 5211 direct mounting platform. This allows for quick and easy installation of pneumatic or electric actuators without the need for custom brackets or adapters. The direct mount design also ensures precise alignment between the actuator and valve stem, improving reliability and reducing maintenance requirements.
We offer a wide range of optional features to meet specific application requirements:
Anti-static device for flammable media applications
Purge ports for cleaning and sterilization
Heating jackets for viscous media that require temperature control
Body cavity fillers to prevent media entrapment
Inclined stem design for improved accessibility in tight spaces
Our tank mounted flush bottom ball valves are widely used across various industrial sectors where efficient and complete fluid discharge is essential. Typical applications include:
Pharmaceutical reactors and processing equipment
Food and beverage processing tanks
Cosmetics and personal care product vessels
Chemical mixing plants and storage tanks
Bioreactors and fermentation systems
Industrial containers and process vessels
These valves are particularly well-suited for applications requiring frequent batch changes, strict hygiene standards, or handling of viscous, abrasive or solid-laden media.
