Austria
An underground supply line in the tunnel system for firefighting operations required a safe and maintenance-free solution for the implementation of suitable shut-off valves. The KLINGER Ballostar was able to successfully establish itself here with its significant product advantages, as its robustness combined with its unique sealing system meets the highest quality standards.

A chemical plant using the KLINGER KVN piston valve in a condensate collector produces phthalic anhydride. This process requires an immense amount of steam. In order to shut-off or by-pass the existing steam traps for maintenance the operator was looking for a safe and cost effective solution over the complete life cycle of the used shut-off valve. The KLINGER KVN piston valve with its guided piston construction is insensitive against pressure surges and is therefore the ideal solution for such applications. It ensures reliable tightness for decades, easy maintenance and prevents from financial losses caused by leaking steam.

The plant, where the operator decided to use KLINGER Fluid Control Ballostar KHI, is used to reduce the carbon content from approx. 4,5% to 0,03-0,04% using the Linz Donawitz process. This process requires blowing pure oxygen at a pressure of 12 bars on the raw iron for about 15 minutes to finish that process. The KHI ball valves are fulfilling up to 10.000 opening cycles (with a maximum closing time of 3 sec.) per year. For 30 years, the operator did not have a malfunction occurrence or any other problem related to the installed valves.

A valve was required for installation on a rail tank car for loading and unloading liquid ammonia. Due to temperature changes, the expansive behavior of ammonia can cause damage when using a valve. The ammonia version of the KLINGER Ballostar KHA was equipped with a special stuffing box featuring ammonia-resistant O-rings and an upstream sealing element with a pressure relief bore. This bore provides additional pressure equalization for the valve cavity to prevent excessive expansion of the medium inside the valve.

As part of the construction of the Grand Paris Express, Idex La Défense is upgrading its heating and cooling networks by replacing pipes with larger diameters to enhance system efficiency and meet increased demand. To meet these new requirements, KLINGER Fluid Control supplied several units of the KHSVI ball valves that have been successfully tested to ensure they meet stringent specifications for safety, reliability and durability.

The requirements from the district heating company on a valve were to get a valve with a long service life, extended shaft, maintenance free, fulfillment of EN 488, operable with a T-wrench and easy to install. The unit was installed in an underground concrete channel with operation possible from ground level. KLINGER offered the Monoball KHO fully welded, tested acc. EN 488 with an extended shaft with a square end and stop on top. Maintenance is not necessary because of the reliable construction of ball stem and sealing system. Several KHO ball valves were installed.

In Germany, a gigantic heat storage facility was equipped with 25 KLINGER Ballostar ball valves, some of which are also used in the pumping station. This major project is part of the energy transition and protects the city's district heating network from short-term outages. Like an oversized thermos flask, the 55-meter-tall giant stores enough thermal energy to supply district heating customers with hot water for heating and household use for up to a weekend. In addition to reliability and availability, a long-term, effective maintenance strategy was also a decisive argument for the use of KLINGER valves.

The customer intended to use two existing DN 1400 pipelines to include them in the new plant section. It has been shown that it is technically better to install a DN 1000 ball valve with extension cones (DN 1000 to DN 1400) instead of butterfly valves of the same size. A KHI DN 1000 has a significantly higher KV value than a butterfly valve DN 1400. This fact prevents from hydraulicly problems in the future and saves costs during operation. Besides time and cost savings, the Double Block & Bleed function was the key convincing factor for the choice of the KLINGER Ballostar.

Geothermal water has the negative side effect of causing deposits to form when pressure fluctuates in the system at operating temperatures above 70°C. The geothermal plant in Germany was affected by this "scaling effect" and replaced the existing butterfly valves with KHI ball valves with metal sealing elements and additional flushing/drain connections to significantly reduce turbulence in the system and thus the effects of calcification. Since then, the operator no longer has to shut down the valve cleaning process, and in addition to cost savings, plant availability has also increased.

Our recommendation for one of the largest district heating providers in Italy to use a pre-insulated fully welded ball valve with a mechanical gearbox and an underground extension telescope won over the client.

KLINGER Ballostar KHI ball valves in line size DN 200 were installed in transportation lines on top of a cement tank to carry cement powder. In this application the particular media is compressed air and cement powder. Hence the challenge for the valves is to handle media with abrasive solids. The end user required both an absolute tight shut off mechanism and a maintenance free operation for this application. Despite an abrasive solid containing media, KLINGER Ballostar KHI ball valves with soft sealing elements KFC (leakage rate A) were used and are working perfectly in this case.

A ball valve for liquid CO₂ and oxygen at -196 °C with leakage rate A was required for a supply line. KLINGER supplied a special Ballostar KHA design with PTFE seals, an extended spindle, a pressure relief bore, and an oil- and grease-free stainless steel body. The bore ensures pressure equalization in case of ice formation, while special low-temperature lubricants and PTFE sealing materials guarantee reliable operation at extremely low temperatures.

The end user searched for a valve solution, where a "smooth" opening and closing should be possible to avoid pressure hammers which can destroy the pipeline, other devices and the valve itself. The KLINGER solution was a KHSVI ball valve with electric actuator from AUMA with a drain/test cock (double block & bleed) for maximum safety. Also a bypass pipe with an installed piston valve ensured the smooth opening/closing function.

South Korea
The biggest district heating provider in South Korea decided to extend their distribution network to improve heat transfer from the production facilities to commercial and public locations. As the distances between the main shut-off valves are quite long, it was of highest priority to install maintenance-free valves which ensure reliable operation for decades. Finally, the district heating provider was absolutely convinced that there is only one choice - KLINGER ball valves. In the end, the valve package included 16 pieces DN 600 fully welded ball valves type KLINGER Ballostar KHSVI VVS acc. to EN 488 standard.
