• Long Service Life – Premium stainless steel construction and FDA-approved seals ensure exceptional durability under repeated CIP/SIP cycles

• Flexible Automation Ready – Interchangeable actuator design allows easy upgrade from manual to pneumatic or electric operation

• Leak-Proof Reliability – Opposing body bolt design and positive sealing ensure secure, vibration-resistant performance

• Versatile Applications – Suitable for food processing, beverage production, dairy, pharmaceutical, biotech, cosmetics, and chemical industries

• Multiple Seal Options – Choice of Silicone, EPDM, or Viton seals to match specific process media and temperature requirements

How It Works

The SIG/16 Sanitary Manual Butterfly Valve operates on a simple yet highly effective quarter-turn principle:

1. Flow Control – A stainless steel disc is positioned within the valve body, rotating on a central stem to regulate flow

2. Handle Operation – The stainless steel pull handle rotates the disc 90 degrees from fully open to fully closed

3. Position Locking – The 12-position spring-loaded locking mechanism allows the handle to be securely locked at any position for precise throttling

4. Sealing – When closed, the disc compresses against the FDA-approved elastomer seal (EPDM, Silicone, or Viton), creating a bubble-tight shut-off

5. Connection – Tri-clamp ends connect to mating ferrules with a sanitary gasket and clamp, creating a hygienic, leak-proof seal

6. Cleanability – The smooth, crevice-free design and sanitary finish support CIP (Clean-In-Place) and SIP (Sterilize-In-Place) procedures without disassembly

This design provides reliable, hygienic flow control with the flexibility of manual operation and the option for future automation.
