Rubberlined Butterfly Valves

We offer an extensive range of extremely durable butterfly valves under the well-known brand name Wouter Witzel. With our multiple choice in styles, materials and sizes, we cover many light- general- and heavy duty applications. Our famous and unique vulcanized bonded liner and profiled disc design has taken functional performance to highest levels.

True dedication creates a clear value proposition to our customers. Decades of application driven know-how, material behavior research and innovation in efficient manufacturing technologies, resulted in our excellent product performance.

Designed in compliance to latest international standards and regulations, we make sure to meet latest environmental friendly requirements. For many years, Wouter Witzel rubber lined butterfly valves are exchanged against conventional types of valves.
