Sanitary Tie Rod Type Butterfly Welded Ball Valve

High-Performance Hygienic Valve for Industrial Applications

1. Product Overview

The sanitary tie rod type butterfly welded ball valve is a specialized hygienic valve designed for high-purity pipeline systems that demand precise flow control, structural stability, and long-term reliability. Crafted from SS304 or SS316L stainless steel, the valve features a polished interior surface (Ra ≤ 0.8 μm) for complete drainage and contamination-free operation.

The tie rod construction enhances mechanical strength, ensuring stability under high pressure, while the welded body provides leak-proof performance. Ideal for food, beverage, dairy, pharmaceutical, and biotechnology industries, this valve supports CIP (Clean-in-Place) and SIP (Sterilization-in-Place) processes.
