In the realm of Building Services WWE offers a complete range of butterfly valves and actuators to be fitted in a wide variety of fully automated systems. With an installed base of about three million valves WWE is a undisputed favourite worldwide.
WWE supplies a wide range of rubber lined butterfly valves perfectly suited to be used in buildings and swimming pool installations. 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:
- Heating systems
- Ventilation systems
- Air conditioning (HEVAC)
- Swimming pools
For buidling services 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 the building industry meet this marketís 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. Whatís 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 vulcansed sealing. 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 building processes; reliability and durability. For more information about our Wouter Witzel valves, click here.
The high-quality, durable butterfly valve for heavy duty applications. The building services 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.
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 building 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. For more information about our actuators, click here.
