New high strength top works execution on the WB valve range up to DN 600/24"

 
The coated steel beams supplied earlier on the WB range (WB, WB11, WB12 and WB14) up to DN 600/24" have been replaced by Stafsjö’s high strength top works with stainless steel tie rods encapsulated inside structural aluminum beams together with stainless steel gate guards on remote operated valves. This new standard execution offers great corrosion resistance and a precise gate alignment independent of valve position.

After 350 years Stafsjö Valves are stronger than ever

In recent years, Stafsjö has invested over SEK 50 million in order to expand. Within four years the turnover should be SEK 200 million annually. This goal will be attained with new products within new market sectors as well as new countries, whilst simultaneously strengthening the position on existing markets.

– Innovation and local availability worldwide are our strengths, says Thomas Carlson, the President of Stafsjö. 

–Together with our customers we work to understand the demands placed not only on today’s processes, but also those of tomorrow. By ensuring that our valves are in stock around the globe we operate as a fast and flexible supplier of high performance knife gate valves for complex processes in varying dimensions, he adds.

Stafsjö may be something of a ’dark horse’, but it is a well known name amongst major players within paper and pulp, mining, power generation and water treatment. Over 1 million of our valves have been installed around the world and 86% of the production is exported. Growth markets are the USA, Australia and South East Asia, the latter primarily driven by Indonesia. An initiative made in the mining industry in Mexico has also been sucessfull.

– We now have a product portfolio covering a considerably broader range. Our long experience of tight shut-off valves for full flow applications enables us to allow our development team to push this technology still further, says Carlson. 

Established already in 1666, Stafsjö is today one of the oldest operating company in Sweden. Production commenced with the manufacture of cannons for the Swedish armed forces and remained the core business activity for two centuries. In 1881, the production of valves started and in 1928 the first knife gate valve was launched for the paper and pulp industry in the region.

Since 2005 Stafsjö has been owned by Ebro Armaturen Gebr. Bröer GmbH headquartered in Hagen, Germany, and a specialist in production and development of butterfly valves. With Stafsjö’s knife gate valves, the group can offer a complete range of valves for the process industry. Bröer Group has around 1000 employees and is represented at 26 locations across the globe. A 70-strong workforce is employed at Stafsjö. In the financial year 2015, the Bröer Group generated revenues of EUR 160 million.

 

If you wish to conduct your own interview with Stafsjö’s President, Thomas Carlson, who can tell you more about our product development, new products and production, take advantage of contacting him directly and arrange an appointment.

The 350th anniversary celebrations commence with speeches and a cannon salute at 17.00 Thursday, May 26. Thomas Carlson can be reached on Tel +46 (0)11-36 75 55 or by e-mail thomas.carlson@stafsjo.se 
 

Stafsjö expand in Australia, South and North America with the new WB14E

After extensive collection of customer input converted into product features by a dedicated engineering team with a strong focus on quality in every detail and later first rate manufacturing, the high performance WB14E knife gate valves are now on its way to the market. Stafsjö’s WB14E is a high performance shut-off valve with superior flow characteristics, offering bi-directional zero leakage shut-off up to 150 psi/10 bar up to 24” (DN 600). It is suitable for media such as pulp stock, chemicals, slurry, sludge, bio mass and water.

During the past years Stafsjö has invested significantly in development of new products in order to expand the business into new field of applications. A strong focus has also been to extend the product range and to customize solutions in order to meet new and challenging process demands from markets and applications Stafsjö historically has worked with for a long time, such as the pulp and paper segment.  The new WB14E knife gate valve will strengthen our position on some target markets, applications and helps us grow into new segments as well.

- We have seen a strong demand from especially the North American and Australian markets for WB14E – a high performance fully lugged shut-off valve with superior flow characteristics offering bi-directional tight shut-off. As one of the pioneers and still leading brand in knife gate solutions we wanted to strengthen our position on the target markets and further establish ourselves as a trusted partner to segments like pulp and paper, mining and mineral processing, water and waste water handling and power plus various other process industries with a need for a valve offering reliable and zero leakage shut-off. With over 100 years experience of valve manufacturing and more than a million valves installed worldwide we are confident this WB14E will also provide reliability to our customers process systems with a competitive cost of ownership, says Maria Persson, Sales and Marketing Director at Stafsjö.

Stafsjö 350 years – from royal cannons to a world leading knife gate valve manufacturer

It all started out with manufacturing of cannons and it became a nearly 200 year long tradition (1666-1859). Today Stafsjö is a globally leading supplier of knife gate solutions for shut-off and flow control within the process industry. We have over 1 million valves installed worldwide. Major players in pulp and paper, mining, power and water utilities depend our valve solutions reliability and performance every minute, every day, year after year.

Already in 1881 the first valve was manufactured at Stafsjö – a gate valve. The manufacturing of knife gate valves started in 1928 in close co-operation with the near-by pulp and paper mills. The first knife gate valve came with a bottom pocket (draining pocket) and pretty soon thereafter a model came without bottom pocket. The name for these valves was Pulp Valve and they were available in sizes DN 80 up to DN 500. A control valve was also developed.

During the first manufacturing years the valve came in cast iron. In mid 1930’s, valve parts such as valve body, gate and gland were available in acid-proof metal (bronze). On request, valves in acid-proof steel were also available.

Leveraging on this long experience of tight shut-off valves for full flow applications we continue to focus our development team to push this technology as far as possible. And through our sister company Ebro Armaturen and external sales partners, we are able to provide fast deliveries, high quality service and support to local markets worldwide.

Stafsjö invest in increased capacity

Stafsjö, a company in the German Bröer Group, has recently made substantial investments to increase capacity and raise production efficiency. The investment, that amounts to 2,3 M EUR, includes among others two new multi-operation machines, three new assembly and pressure testing lines and a new testing facility for product development and R&D.

– Now we have the opportunity to increase our capacity, to be even more flexible than we are today and above all to meet the increasing demand of our products. This and other investments during the past years, clearly states that our owner, the German family owned company Bröer Group, truly believe in our strategy and on a long-term ownership, says Thomas Carlson President/CEO at Stafsjö.

The investment in the two new machining centers is only one in a series carried out in the recent years. In 2007 a new multi-operation machine were acquired to machine valves up to DN 1600 and a few years later a new grinding machine were acquired. This year Stafsjö’s research and design department also have expanded and modernized its testing facilities to meet the demand for larger valves and products for the mining industry, Stafsjö’s fastest growing business segment. As part of Stafsjö’s lean strategy, integrated assembly and pressure testing lines are also installed. This is an important element in streamlining and optimizing the production, according to Thomas Carlson.

About the multi-operation machines
HC Nexus 6800-II from Mazak is a flexible and modular designed machining centre which will be used to machine valve bodies. It has 180 tool pockets and 12 pallets which gives flexibility, speed and minimal down time. MVC 1600 from Spinner will mainly be used to machine gates.
