Jan 2021 | Adjustable sliding gate orifice - Type 8090

The adjustable sliding gate orifice type 8090 uses almost the entire performance of the GS1/GS3 proven GS valve series and is suitable for precise and continuous adjustment of a defined flow. It can be adjusted and secured manually in the installed state during operation. Stops in the end positions and a high-resolution position indicator enable reproducible setting. Among other things, the orifice facilitates the hydraulic adjustment of cooling systems, e.g. when commissioning large engines in CHPs and on ships.

Nov 2020 | Press Release - Compact manifold for cooling and lubrication of the shaft seal on centrifugal pumps

Centrifugal pumps depend on cooling and lubrication to operate efficiently, reliably and with a long service life. The solutions commonly used for this purpose in the industry are mostly constructions made of a lot of different components. These are often not exactly matched to each other and also require a lot of space and installation effort.

Schubert & Salzer Control Systems has now developed an out-of-the-box solution for this specific application. In this case, the cooling and lubrication of the shaft seals in centrifugal pumps with the operating fluid is controlled via a compact manifold. The adjustable 7010 angle-seat shut-off valve integrated into the block allows a flow rate of 10 to 50 l / h to be set.

When the pump is started, the pneumatic valve opens simultaneously, so that cooling and lubrication are ensured immediately. The liquid sensor integrated in the manifold permanetly checks that coolant always flows when the pump is running. If there is no cooling the pump is switched off to prevent damage to the shaft seal and to prevent it from getting stuck. The switch-off and switch-on functions can be carried out via the pump control or can be taken over by a PLC.

Schubert & Salzer Control Systems thus offers an efficient out-of-the-box solution for the cooling and lubrication of shaft seals in centrifugal pumps. As a complete solution, the new system is not only more compact than the solutions commonly used in industry, but also significantly reduces installation and maintenance costs.
The manifold is suitable for all centrifugal pumps within the specified performance range. In addition, it can be extended with e.g. manometer connections, pressure and temperature sensors. Further options and intelligent, specific, modular solutions are also possible.

May 2020 | KS2 – The next generation of the ball sector valve

  • Extended application limits between -40°F and 428°F
  • Also suitable for use with steam applications
  • Much easier to mount/remove
  • Reduced maintenance costs
  • Additional nominal widths of 2 1/2" and 5" available
  • All known benefits of the previous KS1 design

With the redesigned KS2 ball sector valve, we have especially succeeded in extending the warranted application limits of this valve series as far as the application temperatures are concerned. The redesigned shaft seal and seat area now enable it to be used within a temperature range of between -40°F and 428°F, so that steam applications are now possible. Not only do the shaft seal that is held by a circlip make mounting and removal easier, this is also due to the screwed retaining and supporting ring on the seat area. Not only that: the series has also been extended by the nominal widths 2 1/2" and 5" in addition to a dihedron shaft connection.

Sep 2019 | Press Release - New Desuperheater with Segmented Disc Valve Controls Nozzle by Nozzle

Steam is not only a supplier of energy, but is also an important source of energy for a wide variety of processes for all operators of thermal systems such as producers of sugar or paper. Using desuperheaters, it is easy to control the pressure and temperature of the steam and condition overheated steam for the particular consumer in the process.

Desuperheaters have proven effective for injecting cooling water or condensate into overheated steam. Producing slightly overheated steam that is 3-20 K above the saturated steam temperature to subsequently provide consumers with steam with an optimal heat transfer coefficient is a specialized art. Schubert & Salzer has developed a completely new kind of desuperheater by integrating a segmented disc valve with four injection nozzles on the lance. This enables the outstanding advantages of this valve technology to be used for the finely tuned regulation of steam networks. [...]
