What Makes Wouter Witzel Butterfly Valves a Superior Choice?

Most of you reading this likely know about butterfly valves and what makes them an excellent choice and an exceptional value. But for those of you not acquainted, here is a simple primer. A butterfly valve is a quarter-turn valve used to isolate or regulate flow. It accomplishes this through the use of a metal disc in the body of the valve, which is positioned perpendicular to the flow in the closed position, and rotated one quarter of a turn to be parallel to the flow in the fully opened position.

A popular choice because of their thin profile between flanges, reduced weight and smaller footprint when installed, butterfly valves are very precise, which makes them advantageous in industrial applications. They are extremely reliable and are often preferred due to their low maintenance and overall cost requirements.

World-renowned for their high-quality European craftsmanship, Wouter Witzel EuroValve Butterfly Valves are unique due to their innovative design and state-of-the-art materials. The bonded-to-body vulcanized rubber lining adheres directly onto the valve body forming a permanent bond and ensuring increased operational life. This manufacturing process ensures a perfect inner lining profile that seals the disc and integral flange gaskets. One of the major benefits of this process is increased operational life because any scuffing resulting from liner distortion is eliminated.

Wouter Witzel full bore butterfly valves feature special low profiled and streamlined discs, resulting in low-flow resistance and reduced energy costs. Lower operating torque means less wear and tear of the lining, making the valves more reliable and more efficient than other butterfly valves. Suitable for high-cycling frequencies, the energy cost savings of a Wouter Witzel Eurovalve may be several times the initial cost of the valve.

In 2016 Wouter Witzel celebrated 50 years of business excellence, and announced that they will now offer an unmatched 5-YEAR GUARANTEE on the rubber lined butterfly valve range. By becoming the world’s first manufacturer of butterfly valves to explicitly guarantee their valves with this warranty, Wouter Witzel again sets the standard for innovation in the industry.
