Product Recommendations

 

Product Description

• 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.
