• Extended application limits between -40°C and 220°C
• Also suitable for use with steam applications
• Much easier to mount/remove
• Reduced maintenance costs
• Additional nominal widths of DN65 and DN125 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°C and 220°C, 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 DN 65 and DN 125 in addition to a dihedron shaft connection.

The pneumatic 7032 stainless steel flange valve is now also available in wider nominal sizes. The nominal size DN 15, 20, 25, 32, 40 and 50 that were available in the past have now been supplemented with DN 65 and 80. All of the valve components that come into contact with the media are made of high quality stainless steel. The installation length and the flange pattern comply with DIN and ANSI.

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. ºÚÁϸ£ÀûÉç 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. [...]

A high control precision requires an almost backlash-free transmission of the actuating forces to the valve seat. This is the only possibility for the set point to correlate with the opening angle of the valve and the resulting volume flow. The electrical actuator, Type S1500, is able to break a 90° rotary movement down into a maximum of 1,500 steps and also reduces the hysteresis to under 0.15%. A compact actuator transfers the actuating rotation to the valve seat – the ball sector – with almost no backlash.

By combining the precise motor actuator and the robust ball sector valve, ºÚÁϸ£ÀûÉç has succeeded in manufacturing an accurate and reliable control valve for large volume flows with an enormous rangeability. The set point can either be 4 – 20 mA or 0 – 10 V according to choice and a position feedback is provided via 4 - 20 mA. The valve assembly that comprises the actuator and the ball sector valve is IP67 rated and designed for ambient temperatures of between – 40°C and + 80°C. The ball sector valve in its wafer design is available in sizes from DN 25 up to DN 250 and for a nominal pressure of up to PN 40 for flanges that are conform with DIN EN 1092-1. The actuating time for a 90° rotary movement is approx. 20 seconds and the operating time with an OT of 100 % leaves nothing to be desired. Of course, an emergency manual override is also available.

It was possible to integrate the ingenious and space saving design in the head section of the valve. Due to the differential pressure, assisting the actuator, it is possible to reduce the actuating force by approx. 97%. This means that the especially designed Type 7010 angle seat valves and the Type 7210 angle seat motorised control valves are a real alternative when it comes to very high differential pressures with much smaller actuators.

The balanced trim design is available for stainless steel angle seat valves in size DN32 up to DN80. With the selection of temperature-resistant sealing materials, it could easily be used in steam applications up to 220°C, for example.
