Stainless Steel Sanitary Flange Butterfly Valve

Thisstainless steel sanitary flange butterfly valve is engineered for hygienic fluid control in pipelines across food, dairy, beverage, pharmaceutical and chemical industries. It delivers reliable shut-off and flow regulation with a compact flange-to-flange design and a smooth, crevice-free bore that meets strict sanitary standards.

The valve body, disc and stem are available in SS 316L or SS 304, offering excellent corrosion resistance and long service life. The multi-position manual handle provides precise flow control, while the optional electric or pneumatic actuator mount makes it easy to upgrade to automated process control.

1. Hygienic flange construction F: One-piece forged body with mirror-polished wetted surfaces. A: Reduces media residue and bacterial growth risk. B: Ideal for CIP/SIP systems and clean process lines.

2. Quick 90-degree operation F: Multi-stop polymer handle with spring return option. A: Operators can set flow precisely and release to close automatically. B: Saves operation time and prevents accidental backflow.

3. Wide size and seal range F: DN15 to DN300 with EPDM, PTFE or silicone liner choices. A: Covers almost every hygienic pipeline specification. B: One supplier reduces procurement and spare-part complexity.

4. ISO-compatible mounting pad F: Top flange drilled per ISO 5211 for actuators and gearboxes. A: Direct electric or pneumatic actuator installation without adapters. B: Future automation upgrades are fast and cost-effective.

5. Leak-free flange gasket sealing F: Precision-machined flange faces with replaceable liner. A: Maintains tight seal across pressure and temperature cycles. B: Low maintenance downtime and reliable process integrity.
