Hygienic Valves
From simple on/off duty to aseptic processing and mixproof separation, Alfa Laval’s hygienic valves cover the full spectrum of sanitary flow control for food, beverage, dairy, and biotech applications. Available in manual and pneumatic actuation with a complete range of positioners and feedback, the portfolio includes:
Butterfly (LKB / LKB-F)
Cost-effective in-line isolation; manual handles or air actuators.
Single-Seat Shut-off & Changeover (Unique SSV / SSV Aseptic)
Reliable product/CIP routing with excellent cleanability.
Mixproof (Unique Mixproof / PMO / CP-3)
Double-seat design allows two fluids in one manifold without cross-contamination; ideal for high-utilization dairy and CIP.
Ball (SBV)
Full-bore, minimal pressure drop for viscous or particulate media; manual or automated.
Diaphragm (Unique DV-ST UltraPure)
Aseptic valve series for high-purity service in pharma/biotech.
Regulating/Control (Unique RV-ST)
Precise, continuous control of flow, pressure, or temperature.
Sampling (SMP / SB)
Sanitary and aseptic point-of-use sampling solutions.
Automation
For pneumatically actuated valves, we pair with Alfa Laval ThinkTop® V50/V70 control tops—single-sensor, auto-setup in seconds with a 360° status LED, IO-Link connectivity, and rugged IP66/67/69K protection—compatible across DV-ST diaphragm, butterfly, single-seat, and mixproof valves; optional Burst/Pulse Seat Clean can cut CIP use on mixproof/drain valve cleaning by up to 90–95%.
