Hygienic Design
Smooth, crevice-free surfaces and polished finishes meet strict sanitary standards (e.g., FDA, EHEDG, 3-A), preventing bacterial growth and ensuring cleanability.
Non-Contaminating
Constructed from high-quality stainless steel (e.g., 316L) with compliant diaphragms (e.g., PTFE, EPDM), ensuring no contamination of process media.
Leak-Proof Operation
The diaphragm isolates the fluid from mechanical parts, eliminating leakage risks and enhancing seal integrity.
Bubble-Tight Shutoff
Provides reliable sealing even for viscous or particulate-laden fluids, critical in sanitary applications.
Corrosion Resistance
Stainless steel construction resists rust, chemicals, and high-pressure cleaning (CIP/SIP compatibility).
Pneumatic Actuation
Enables quick, automated control (on/off or modulating) without manual intervention, improving efficiency.
Low Maintenance
No internal seals or moving parts in contact with fluid reduce wear and simplify upkeep.
Versatile Flow Path
Full-bore or reduced-port designs accommodate various flow rates with minimal pressure drop.
Bi-Directional Flow
Suitable for multi-directional piping systems without compromising performance.
Wide Compatibility
Ideal for food, beverage, pharmaceutical, and biotech industries handling sterile or aggressive fluids.
