Waterbehandeling
In this market Wouter Witzel EuroValve has access to an elaborate network, including contacts with end users, consultants and contractors and further enlarged by the many international offices of our mother company AVK. As a result we can closely monitor developments in this market, respond to them, and, most importantly, offer worldwide services. The water treatment market requires a specific approach; experienced advisors with knowledge of the many applications and processes, fast and adequate service and, especially, a high degree of reliability of the products and materials used. They contribute to a successful formula.

Applications
With 40 years of experience Wouter Witzel EuroValve is completely at home in the many processes and applications in the water treatment sector. As a result, our butterfly valves can be found in installations for the treatment of e.g. drinking water, waste water, industrial process water, but also in pumping installations and water transport piping. Besides functioning as blocking valves Wouter Witzel butterfly valves are also used as control valves. For many drinking water companies and large industries Wouter Witzel EuroValve has become an important partner in the production process.

The ever increasing complexity of the various water treatment processes also requires our products to be even more reliable and durable. This not only goes where they are used as valves but especially in situations where they are an essential component of total process automation. From traditional sand filtration to reverse osmosis (membrane filtration), disinfection with ozone, chloride or UV and water quality improvement by means of e.g. softening – for all these processes Wouter Witzel EuroValve offers a wide and affordable range of valves. Wouter Witzel EuroValve butterfly valves have earned many international quality marks.

Especially in the drinking water market these quality marks serve as a guarantee that the proper materials are used.

Products
For the water treatment process we offer three product lines: rubber lined butterfly valves, high performance butterfly valves, and actuators.


Wouter Witzel rubberlined butterflyvalves
Wouter Witzel EuroValve butterfly valves for use in water treatment systems meet this market’s specific demands. There is a wide choice of materials and coating systems on offer. A material often used for the valve disc is corrosion proof and wear resistant duplex stainless steel. This material is very suitable for use in e.g. membrane filtration or demineralised water, because of its resistance to chemicals. What’s more it offers sufficient strength when pressure rises up to 25 bar. Additionally, we offer many sealing materials, such as EPDM, NBR, Viton and silicon rubber. As a producer we make it possible for butterfly valves to be supplied with coating that matches your specifications. With diameters of DN 40 up to even DN 2200 and an impressive range of butterfly valves in types such as wafer, semi-lug, tapped-lug, u-section, single flange and double flange we have every right to call our product offer complete. An important characteristic of our butterfly valves is the centric design and the vulcanised s aling. As a result our butterfly valves offer important advantages, such as a low and reliable operating moment, being suitable for many operating cycles and excellent protection of the valve casing. These very properties matter especially when it comes to water treatment processes; reliability and durability. For more information about our Wouter Witzel valves, click here.


Dynaxe
The high-quality, durable butterfly valve for heavy duty applications. Industrial water treatment especially implies high pressures, high temperatures and water with aggressive chemicals sometimes making it impossible for rubber lined butterfly valves to be used. Our Dynaxe high performance butterfly valves have a doubly excentric design and are available in many high-quality materials, including stainless steel 316, duplex steel and Alubronze. They also come with a variety of sealing materials. For more information about our Dynaxe valves, click here.

Actuators
Another important component of the butterfly valve is the actuator. Besides manual operation by means of a lever or gear unit we offer a wide range of automatic actuators and accessories such as terminal switches, regulating valves and positioners for control valves. In water treatment process automation it is of the utmost importance that the right type of actuator be chosen. Wouter Witzel EuroValve has many years of specific experience in this area and can give you the advice you need to make a choice that is both responsible and affordable. Besides our own electric and pneumatic actuators we can supply almost any brand. We are also very experienced in assembling, setting and testing actuators. This is only natural, as the combination of actuators and Wouter Witzel butterfly valves largely determines the reliability of your installation.
