How It Works

The Sanitary Manual Butterfly Valve Mod.SIG/19 operates on a simple yet highly effective principle:

1. Flow Control Mechanism – A disc (butterfly plate) is mounted on a rotating shaft within the valve body

2. Handle Operation – The stainless steel lever handle is turned to rotate the disc

3. 90° Rotation – Rotating the handle 90° moves the disc from fully closed (perpendicular to flow) to fully open (parallel to flow), or to any intermediate position for precise flow regulation

4. Position Locking – The 12-position handle allows the disc to be locked at multiple angles, providing repeatable, precise flow control

5. Sealing – The disc compresses against the seat (EPDM, Silicone, or Viton) to create a tight, leak-proof seal when closed

6. CIP/SIP Compatibility – The smooth, crevice-free design allows cleaning and sterilization fluids to flow through effectively, maintaining system cleanliness without disassembly

This design provides a reliable, hygienic, and user-friendly solution for flow control in sanitary processing systems.
