When your process requires full-bore, unrestricted flow with zero dead legs, a sanitary ball valve is the right choice. The spherical closure element rotates 90 degrees between open and closed positions, providing a straight-through flow path that minimizes pressure drop and allows complete drainage — two properties that matter in every hygienic ball valve application from CIP return lines to high-viscosity product transfer.

What Brings Buyers to Sanitary Ball Valves
High-viscosity product will not fully drain, failing CIP validation
Butterfly valves leave a disc obstruction in the flow path that viscous products like thick sauces, yogurt, cream, paste do not clear during CIP. The valve fails swab testing.
Solution: Full-bore sanitary ball valve has zero obstruction. The 90-degree bore aligns completely with the pipe when open, leaving no retention surface.Tank bottom drain creates a dead leg that breeds bacteria
A standard elbow-and-valve outlet leaves 50-150 mm of stagnant product below the valve seat, a biofilm growth zone that CIP flow cannot reach.
Solution: Sanitary bottom ball valve mounts flush with the tank floor, zero dead leg, complete drainability in both open and closed positions.Acid or solvent is corroding through the valve body
316L stainless is attacked by concentrated hydrochloric acid, acetic acid above 20%, and chlorinated solvents, leading to pitting, product contamination, and valve failure.
Solution: PTFE-lined ball valve eliminates all metal-to-fluid contact with a chemically inert lining.Two-tank switching requires stopping production to manually redirect flow
If switching product between tanks requires closing one valve and opening another manually, there is a window where both are partially open, allowing cross-mixing.
Solution: Three-way ball valve switches flow direction in a single quarter-turn, no intermediate open position, no cross-contamination window.All Sanitary Ball Valve Models

Where Sanitary Ball Valves Are Installed
| High-Viscosity Food and Dairy | Cream, yogurt, cheese sauce, honey, jam, thick condiments. Full-bore ball valve is the only valve type that handles high-viscosity media without product hold-up or CIP failure. Widely used in European and Southeast Asian dairy exports. |
| Pharmaceutical and Bioprocess | Buffer tanks, sterile water loops, API solution transfer. Three-piece body allows inline seat replacement without removing the valve from the pipe, critical for continuous manufacturing lines. |
| Chemical and Solvent Lines | Concentrated acids, chlorinated solvents, reactive cleaning agents. PTFE-lined ball valves provide full chemical inertness, specified in fine chemical plants in Germany, France, and China. |
| Brewing, Winery and Spirits | Tank-to-tank transfer, centrifuge outlet, filter outlet. Bottom ball valves on fermentation and bright tanks eliminate the dead leg that standard outlet configurations create. Common in craft brewery equipment exports to the US and Mexico. |
Frequently Asked Questions
Ball valve or butterfly valve - which is better for sanitary applications?
Ball valves provide full-bore, zero-obstruction flow with complete shut-off, essential for high-viscosity products, dead-leg-free tank drains, and slurries. Butterfly valves are more compact, lighter, and lower cost, making them the standard choice for thin liquids, CIP water circuits, and high-frequency automated switching. The choice depends on your media viscosity, pipe size, and cycle frequency.
What is a tri clamp ball valve and how does it differ from a standard ball valve?
A tri clamp ball valve uses sanitary ferrule ends secured with a clamp band rather than threaded or flanged connections. This enables tool-free disassembly in seconds, essential in food, dairy, and pharmaceutical facilities where the valve must be removed, cleaned, and reinstalled multiple times per shift. All wetted parts are polished to Ra 0.8 um and manufactured from FDA-compliant materials.
Can a three-way ball valve replace two separate two-way valves?
Yes. A T-port three-way ball valve handles the function of two standard 2-way valves with a single actuator stroke. This reduces pipe complexity, eliminates one actuator, and cuts maintenance points by half for standard two-tank switching or product diversion applications.
Are HEYI sanitary ball valves compatible with CIP cleaning systems?
Yes. All HEYI sanitary ball valves feature full-bore geometry with no internal crevices in the flow path, PTFE seats rated for standard CIP chemicals, and FDA-compliant body seals. For SIP applications, specify FKM or high-temperature EPDM body seals rated to 140C.
