Sanitary Three-Piece Tank Bottom Flange Ball Valve

High-Performance Hygienic Valve for Tank Bottom Applications

1. Introduction

The sanitary three-piece tank bottom flange ball valve is a specialized hygienic valve designed for efficient drainage and flow control at the bottom of tanks. Constructed from SS304 or SS316L stainless steel, with a highly polished interior surface (Ra ≤ 0.8 μm), this valve ensures hygienic operation, complete drainage, and zero fluid retention.

Its three-piece design enables easy disassembly for maintenance or seat replacement without disrupting the production line. Suitable for food, beverage, dairy, pharmaceutical, biotechnology, and cosmetic applications, the valve is compatible with CIP (Clean-in-Place) and SIP (Sterilization-in-Place) processes, delivering long-lasting, leak-free performance while complying with FDA, CE, ISO9001, and 3A sanitary standards.
