Features & Benefits
- Superior Hygienic Integrity: The valve is constructed from SS304/SS316 stainless steel with a highly polished surface to minimize media adhesion and prevent bacterial growth. Its sanitary-grade design ensures a smooth, unobstructed flow path that is easy to clean and sterilize.
- Flexible & Secure Connections: Choose the connection style that best fits your process. Tri-Clamp ends allow for rapid disassembly for frequent cleaning and inspection, while Butt Weld ends create a permanent, seamless, and exceptionally strong joint within the pipeline.
- FDA-Compliant Sealing: Equipped with EPDM or Silicon food-grade seals, the Hearken valve provides a bubble-tight shut-off that is safe for direct contact with consumable products, ensuring zero leakage and maintaining process purity.
- Washdown-Ready Automation: The IP67-rated pneumatic actuator is fully sealed against dust and water ingress, making it ideal for the frequent washdown cycles common in sanitary environments. It provides reliable and responsive automation for any modern processing plant.
