District Cooling

In this market Wouter Witzel has access to an elaborate network, including contacts with end users, consultants and contractors, and further enhanced by the many international offices of our mother company AVK. As a result we can closely monitor developments, respond to them and, most importantly, offer worldwide services.


We supply a wide range of rubberlined butterfly valves for district cooling systems. These valves are distinguished by robust design, corrosive resistance, minimum condensation and long, maintenance free life thanks to the vulcanised lining concept. Suitable for many water qualities, disinfection systems and chemicals, our valves are used in:


  • Transmission lines (also buried service)
  • Pumping sytems (suction and pressure)
  • Control and Scada systems
  • Disinfection and water treatment systems

Special features are:
Disc material suitable and full corrosion proof for many water qualities (even brackish or desalinated water).
Easy insulation because of compact design energy saving as the rubber liner is a good isolator.


Rubberlined Butterfly Valves

The Wouter Witzel butterfly valve is suited for various applications. For tailored to market needs such as reliability, no maintenance and long service life we have developed a complete range of industrial butterfly valves under the well-known brand of Wouter Witzel.

The unique bonded lining concept and profiled sealing design have improved the functional performance to a very high level, Long application experiences, continuous material research and innovation of efficient manufacturing technologies have resulted in an up-to-date product range.

Desgined in accordance with the latest international standards, our butterfly valves also meet environmental requirements. For many years our centric rubberlined butterfly valves have replaced conventional double eccentric valves or ball valves.

High Performance Butterfly Valve

We classify our high performance butterfly valve in two categories:

  • Dynaxe
  • Econaxe

Dynaxe excels in all markets where the process conditions are high pressure, severe conditions or abrasive media. This high performance valve is extremely durable, has an ultra long life time with low operating costs and meet the most stringent international standards.

Econaxe is a new range of double-offset butterfly valves for applications in various industries and is available in different types and materials. Econaxe is the most economic solution for high abrasive applications.


The Eurocheck valve is a maintenance free self acting pivoting check valve of the double disc wafer type. Special design features and carefully selected materials combine to make the Eurocheck a very reliable product at low operating costs.

This range valves is mainly used in water applications. Their compact design is space saving. Maintenance costs are low to nil and pressure loss has been reduced to an absolute minimum.


The Wouter Witzel philosophy for actuation is being able to supply, out of a wide spectrum of brands and types, the optimum solution for each specific case of valve actuation according to the requirements of different market segments and customers. In order to match the desired quality, specification and performance at the right price, we classify the actuators into three categories:

  • Economic
  • General purpose
  • Heavy duty
