Product Description

The DN50 welded butterfly valve is the standard discharge valve for IBC totes, permanently welded to the HDPE inner tank outlet for a zero-leak-path connection. Its quarter-turn butterfly mechanism delivers instant full-bore flow — critical for viscous liquids that resist flow through smaller-bore valves. The ergonomic lever handle allows one-hand operation in gloved conditions, and handle colour is fully customisable for colour-coded product identification or safety systems.
Jieyuan also supplies a full range of IBC valve types to suit different installation, flow, and application requirements:
  • Standard: Welded Butterfly Valve — DN50, quarter-turn, welded connection
