Stainless Steel Hygienic Pneumatic Actuated Ball Valve
Engineered for absolute purity and reliability in critical process industries, our Stainless Steel Hygienic Ball Valves are available in both manual and pneumatic actuated configurations. These valves are specifically designed to meet the stringent requirements of pharmaceutical, biotechnology, food & beverage, and cosmetic manufacturing, where contamination control, cleanability, and aseptic operation are paramount.
Constructed from certified AISI 304 or 316L stainless steel with mirror-finished internal surfaces, these valves feature zero dead-leg designs and crevice-free construction to prevent bacterial harborage and facilitate effective Clean-in-Place (CIP) and Sterilize-in-Place (SIP) procedures. The manual versions provide precise, tactile control for routine operations, while the pneumatic actuated models enable automated process control, rapid shut-off, and integration with modern Process Control Systems (PCS). Both types ensure bubble-tight sealing and compliance with global hygienic standards.
Product Detailed Description
Hygienic Design & Construction:
The valve body is precision investment cast or forged from 304/316L stainless steel, followed by extensive CNC machining. The design incorporates:
Drainable Body: Fully self-draining angle prevents liquid entrapment
Crevice-Free Internals: Continuous polished surfaces with radii ≥3mm
Quick Disassembly: Clamp or threaded connections for easy maintenance
Stem Seal System: Multiple FDA-grade stem seals with secondary containment
Ball & Sealing Technology:
Precision Ball: CNC-ground and polished to sphere tolerance Grade 25 (max deviation 0.025mm)
Low-Friction Seats: Reinforced PTFE seats with spring-loaded compensation for wear
Bi-Directional Sealing: Equal sealing performance in both flow directions
Fire-Safe Design: Available with metal secondary seats per API 607
