The operating medium water means that despite all advantages, the requirements on the valve technology are higher due to the lower viscosity and low lubricating properties. In addition to stainless steel, also special alloys and surface coatings are applied.
Because of the continuous development of recent years, today the complete assortment of valves range from nominal diameters up to DN300 and nominal pressures up to PN400. Furthermore a special cartridge valve for descaling systems was developed, which is fitted out with soft seat technology due the increased dirt level.
In addition to the oil hydraulic the water hydraulic offers following valve types:
