TALIS UK UNVEILS LATEST ENERGY SAVING BUTTERFLY VALVE

Posted: Monday 11th May 2015

Talis UK, the UK valve, meterbox and water fitting specialist, has introduced a new butterfly valve to its offering. The ERHARD ROCO wave Butterfly Valve aims to establish new industry standards of valve safety, economic efficiency and durability with its innovative, fresh design.

The latest in ERHARD‘s proven range of valves, the ROCO wave represents a new generation of butterfly values. It has been designed in a flow-optimised way so it can safely withstand the force of water, as well as realise the least possible pressure loss compared with other butterfly valves available on the market.

The valve comes with two disc designs – ERHARD’s principle wave disc is the best for standard pressure ratings and small diameter valves, while ERHARD’s new ‘Skeleton’ butterfly disc has been designed for stability and to optimise flow performance for larger diameter valves and higher pressure ratings. As a result, the valves can be operated with the least possible pumping capacity, ensuring permanently low operating costs.

The curved wave shape of the ROCO butterfly valve makes it ideal for seamless opening and closing without resistance, and the addition of the improved slider-crank mechanism (SKG) gearbox, which helps to operate the butterfly disc, helps to slow down the valve’s closing speed. This new feature ensures the valve is closed softly, helping to minimise the danger of pressure surges and leaks.

The valve also benefits from a polygon connection between the shaft and the tilting disk allowing for continuous corrosion protection and clean potable water. In addition to this the torque transmission is more efficient and the load is spread more uniformly over the circumference of the shaft.

As well as boasting reliable, secure and maintenance friendly seals to reduce water leakage, the valve has also been manufactured using high quality coatings to ensure long-term protection against corrosion.

The ROCO wave is available in a range of nominal widths (DN 150 to DN 1600) and pressure ratings (PN 10 to PN 40), meaning it is suitable for an extensive range of applications, either small or large. What’s more, it is suitable for use in plant and pipe networks and for water applications.

Mark Hodgens, managing director of Talis UK, said: “We are really pleased to be able to offer this new product to our customers. Butterfly valves need to be sufficiently stable in order to withstand the tremendous forces of water in a safe way during opening and closing. On the other hand, they need to have minimal impact on the flow rate when the valve is open. The new ROCO wave Butterfly Valve has been designed to do all of this to the highest of standards and is one of the best of its kind on the market. Its optimised valve design provides better flow rates and higher energy efficiency to ensure optimum financial savings.

“Whether it’s used in plants or mounted in the ground, for drinking water or for aggressive media, the durable ERHARD ROCO wave is ideal for any application as its enhanced curved design and robust coating ensures the smooth and easy transportation of valuable water.”
