In the light weight, durability, and good corrosion resistance based on the advantages, GF 567 butterfly valve product line will expand, new products include PP-H from DN350 to DN600.
Thanks to Georg Fischer double eccentric design principles, 567-type butterfly rubber seal between the medium and greatly reduced the contact area. Market from 2005 until today, the design has stood the test of the market and with great success. In aid of double eccentric mechanism, and the support of the transition under pressure sealed, 567-type butterfly valve with the symmetrical design reduces torque than a 50% open, and open the state to achieve the valve plate no contact with the media. Of particular note is that in the chemical industry, which is expressed as two advantages: uniform opening torque makes the valve to open and close more secure while significantly reducing the wear and tear, the valve life expectancy has been extended. Easy maintenance is also reflected in the sealed design: Special flow seal without removing the disc in the case of replacement or shaft, which greatly reduces maintenance time as well as maintenance costs.
Benefit from the double eccentric characteristics, an increase of 567 butterfly valve operations and process safety, higher efficiency, longer life, better chemical resistance. This is the harsh application conditions, such as the chemical industry is particularly important. Other applications include water treatment, swimming pool and water park as well as chemical and power plants and other industrial wastewater treatment system.
In addition, GF flange valve design fit all common standards, just a model to be compatible with all standard piping system. Another significant advantage is that 567-type butterfly valve in comparison with the same size of the metal, the weight of more than 50% in the transport, installation and maintenance advantages.
