Professional products for a wide variety of applications

Water supply
Whether from  rivers,  lakes or  the  ground water – clean  drinking water is a prerequisite for human life. Drinking water is understood as water that  is so clean  that  it is suitable for humans to drink or cook with.

In many  countries the  quality  of this  commodity  is strictly monitored. Water companies therefore have the  task  of thoroughly testing and guaranteeing the water quality from  the  point of extraction, via treatment and  transportation to supplying  the  water to the  end customer. Valves can assist here with perfect technical solutions that  meet all  national and  international require- ments and therefore consistently satisfy the strict hygiene  demands.

 

Dams
Dams fulfil a variety of tasks. They are used to collect water and stave off the risk of flooding, to generate energy, to help make  rivers navi-gable  and to assure the supply of industrial water for industry and agriculture.

Special demands are placed on the valves in the bottom  outlets. Due to the great forces involved in large reservoirs the  forces must be safely  and  reliably con- verted  without damage to the installation. This is associated with a high drain- age capacity  and large flow rates in the shortest possible time. These  functions must always  reliably be available at all times. The use  of valves  in dams is a particularly sensitive issue as they are  often not used  for many years and then have to serve their  purpose smoothly and reliably within a very short time.

Water treatment
Making specific changes to the water quality is known as water treat- ment. Substances are  either removed from  or added  to the  water, or certain parameters are  adjusted (e.g. adjustment of the pH value). For this, physical,  chemical as  well as  biological  methods are  used. Being  100 % suit- able  for drinking  water is therefore of decisive  importance for the  valves used in these processes.

Naturally all the materials, from the metals to the elastomers, used in the valves therefore satisfy the current regulations of many international organisa- tions, and this even applies to the smallest components such  as O-rings.


The extraction and transportation of drinking water, our most important commodity, place special requirements on the quality of valves.
v
alves guarantee safety and functional reliability of dams at all times.
W
ater treatment in modern waterworks or in desalination plants guarantees consistent and high quality of the drinking water.


Storage  installations

Many are  visible  from  a distance, others are  concealed under the ground, but all water storage facilities  serve the same purpose: they store water for covering  peak  demand or bridging  periods of disruption and at the same time  through their  elevated position  ensure the pressure  required in the pipeline  network.

In addition  to the actual storage area, water storage facilities  are also equipped with an area for the entire installation technology responsible for control, filling and  draining, for power  supply  etc.  It is therefore vital that the  valves used  do not affect  the  purity of the  commodity  water. The reliability of the  valve is also of the utmost importance in order to assure its proper functioning at all times. Frequently used  are  pressure and flow control valves, such  as float valves with which  a floating  ball  automatically assure an  adjustable minimum and  maxi- mum water level.


Pumping stations

Pumps are  used  in many water supply systems. They are  required to transport water to the  supply  areas or water towers, in the  extrac-tion of natural water and drinking  water from wells or in pumped storage hydro power plants.

We offer a large number of valves for pumping stations. The range extends from pump start-up valves via pump by-passes and check valves up to air valves for filling and draining the pipelines. In addition to operational safety and a long- service life, the  optimum design of the  installation is at  the  forefront of this application, as only correct dimensioning with optimum flow values  can assure long-term and cost-effective pump  operation with minimum energy  costs.


Pipeline  network

Many thousands of  kilometres of  pipeline   of  various   dimensions ensure that  drinking  water is available at all times and at the  high-est quality in every household and company. Water tanks and towers, as well as numerous hydrants for flushing the pipeline  networks and for supplying  water for the fire service supplement the system.

The special challenge for the  use  of valves  lies  in the  fact  that  pipelines and valves are  generally buried  in the ground. Many valves such  as service clamps, for example, are  not used  there for long periods of time,  but when called  upon they must exhibit full functional capacity  in order to avoid costly and sometimes almost impossible construction work. Extreme robustness, optimum protect  on against corrosion or the external impermeability of gearboxes  therefore play a decisive  role.


Water storage facilities can be in the form of underground tanks or water towers. Pumps are used in many water supply systems to transport water to the supply areas or water towers, to extract natural water and drinking water from wells or in pumped storage hydro power plants. Municipal water distribution encompasses large supply pipelines for entire regions down to the individual house connections.

 

Industry

There  is hardly  an  industrial production process that  can  manage without  water, for which reason a reliable and cost-effective supply of drinking,  industrial and cooling water is a decisive  economic factor. In addi- tion  to water, other media  must be  transported safely,  e. g. chemicals from acidic to alkaline, gases or media  containing foreign  matter. Through  the broad knowledge of its brands can  competently and  flexibly react to even  the most  special requirements and offer highly individual solutions.

The emphasis is on  valves  for  extremely high  pressures and  flow rates, the development and production of which requires an enormous amount of experi- ence and skill. Just as important is our knowledge in relation to special coatings and special materials to be used  in case of problematic substances.


Energy recovery

The use  of hydroelectric power  plants is an important component in the energy  mix, particularly in order to compensate for fluctuations in solar and wind energy  as can be implemented in storage power  plants. For valves  in such  installations, in addition  to many  years of reliable and  precise operation, a high level  of cost-effectiveness is of decisive  importance. This is achieved by, among  other things,  low zeta values. Precise regulation of the valve over a large range is also important.

With its decades of experience, we have  the necessary know-how, not only in the  development and  production, but also  in the  optimum designing of valves for  special solutions, such  as  an  alpine  hydroelectric power  plant  that was equipped with needle valves of the extreme pressure stage PN 160.


P
ower plants

Whether for coal-fired or nuclear power  plants, large quantities of water are required for the cooling. The reliability of circulating water systems in these applications is of extreme importance. Numerous successful installations throughout the world are proof that  valves are meeting these requirements.

Special  challenges can also  be easily overcome, e. g. when the cooling system is operated with seawater and therefore the  castings are  provided  with a spe- cial ceramic internal coating.  Hydraulic  gravity actuators guaranteeing secure operation if the  power  supply  fails  also  provide  additional safety  for butterfly valves and check  valves.


The constant irrigation of large agricultural areas is of immense importance for feeding the world’s population.

The reliable and safe supply of water and other media is a basic factor for many industrial processes, ranging from the chemical industry, via metal processing  to breweries.

The use of clean hydraulic power in pumped storage hydro power plants or drinking water pipelines represents an important component  in the energy mix.

Reliable cooling is required for the safe operation of power plant installations.

Numerous installations throughout the world prove our competence in matters of sewage technology. The range of applications is supplemented with biogas generation plants.

Before the gas can be used on the cooker at home, it has to travel through many kilometres of pipelines and pipe networks.

 

Sewage and sewage treatment

The central task  of sewage technology is the  storage, transporting and  cleaning of waste water as well as industrial sewage and  rain-water run-off. With its broad range we offer the most  extensive spectrum of products on the European market.

For  use  in sewage technology protection against blockage of the  passage is the order of the day. Smooth  and abrasion-resistant passage surfaces are  also required. Particularly in the case of heavily contaminated sewage, great impor- tance is attached to the  choice  of suitable materials and  optimum protection against corrosion.


Gas

Around 50,000 kilometres of pipelines, some with diameter of up to 1.60 m, extend throughout Europe  and  connect the  European trunk pipeline  network with the pipelines delivering the gas from Northern and East- ern  Europe.  For distribution by local  energy  suppliers much  smaller pipelines are used to assure an effective, safe and environmentally-friendly energy supply.

Our valves  are  used  in both  networks and  have  all the  necessary approvals and certificates. When used  in gas pipelines the impermeability of the valve is the uppermost premise. A pressure test  in accordance with international stand- ards is therefore carried out on all our valves.
