The digital positioner type 8049 has received the FM approval (Factory Mutual Approvals) for the USA and Canada. . The version “8049 ExPro-FM” is now certified for use in potentially explosive atmospheres either with intrinsic safety circuits of Class I, Division 1 resp. Zone 0 or with non incentive circuits of Class I Division 2.
Also, the digital positioner Type 8049 ExPro is approved according to 2014/34/EU, ATEX and IEC-Ex.
In May 2021, the German Bundesrat (Federal Council) passed a long-discussed amendment to the Technical Instructions on Air Quality Control (TA Luft), thus specifying among other things stricter maximum values for emissions of harmful substances as well as significantly tightening irrelevance values and minor mass flows.
Following a helium leak test in accordance with ISO 15848-1, a correspondingly high leak-tightness was certified for the sliding gate control valves and ball sector valves from Schubert & Salzer. Therefore, they also meet the higher requirements of the Technical Instructions on Air Quality Control amendment 2021.
With the new types 7017 and 7027, Schubert & Salzer's range now includes two globe valves for regulating and shutting off media ranging from neutral to highly aggressive. In a stainless-steel version with nominal sizes from 1/2" to 2", the two valve types are suitable for a wide temperature range from -22 °F to +392 °F (optionally -148 °F to +428 °F) and for nominal pressures up to 580psi. The straight seat design enables a highly efficient and very simple isolation of the valve itself as well as the welded-on pipeline.
In mining, there are a multitude of demanding applications where Schubert & Salzer valves show their strengths. They control, for example, air in flotation cells, gases in coals seam gas extraction or MIBC on concentrators, and achieve particularly long service lives with wash water in gold or copper mining, but also with abrasive media such as coal dust or ore slag.
Find out which valves are particularly suitable for the various applications in mining and which advantages come with them in the new PDF brochure "Schubert & Salzer - Your partner in mining".
With the new type 8621, Schubert & Salzer combines ASME standards for the first time with sliding gate technology. It is the first sliding gate control valve not to be built in wafer design, but instead on the basis of ASME B16.34 incl. a flange connection according to ASME B16.5. Sliding gate valves can now be selected with a standardized overall length according to ANSI ISA 75.08.01; plant operators can quickly and simply replace traditional globe valves by much more efficient valves with sliding gate technology.
In comparison with globe valves, users of sliding gate valves benefit from critical advantages, such as minimal consumption of energy due to small actuation forces and fast response due to small strokes. Other features are the controllability of high differential pressures with small actuators, low-noise and cavitation-insensitive operation as well as high variable Cvs/Kvs values (you can find out more about sliding gate technology here).
The new sliding gate control valve type 8621 is the first Schubert & Salzer valve to be produced not only in Germany, but also in the USA at our location in Concord, North Carolina.
