Ductile Iron Butterfly Valve is a valve that uses a disc disc as the closing member and rotates 90° around the valve axis to realize opening and closing. It has the following advantages:

  • Ductile iron has good mechanical properties and wear resistance, can withstand high pressure and high temperature conditions, and ensure the stable operation of the valve.
  • Ductile iron has good corrosion resistance and can be applied to various corrosive media, such as sea water, sewage, acid and alkali, etc., to prolong the service life of the valve.
  • Ductile iron has lower cost and weight, which can save material and installation space, and reduce operating costs.
  • Ductile iron has good flow control characteristics, can realize precise opening and closing, and improve the sealing performance and service life of the valve.

Of course, ductile iron is not a perfect material, it also has some disadvantages, such as:

  • The strength and toughness of ductile iron are lower than that of steel, so it cannot bear excessive impact load.
  • Ductile iron has low fatigue strength and is prone to cracks or fractures in long-term use.
  • Ductile iron has low thermal conductivity and is prone to thermal stress or deformation at high temperatures.

In order to overcome these shortcomings, VALTECCN adopted the following measures when designing and manufacturing ductile iron butterfly valves:

  • Select high-quality ductile iron material, and carry out reasonable heat treatment and surface treatment to improve its strength, toughness and wear resistance.
  • Reasonable structural design and process parameters are adopted to reduce stress concentration and deformation, and improve its impact resistance and fatigue resistance.
  • Use effective heat insulation measures and cooling systems to keep the temperature of the valve uniform and suitable to avoid thermal stress or deformation.
