1. Material properties
Chemical properties: If the material is corrosive, such as strong acid, strong alkali, etc., a Stellite valve seat with excellent corrosion resistance should be selected to ensure that the valve seat will not be damaged by corrosion and affect the homogenization effect.
Physical properties: For high-viscosity, particle-containing materials, such as the food industry and cosmetics production, the high hardness and wear resistance of the Stellite valve seat can resist the erosion and wear of the material, maintaining good surface finish and dimensional accuracy.
2. Working conditions
Pressure: Cobalt-based alloys can withstand high pressures. During high-pressure homogenization, the sealing performance between the valve seat and the valve core can be ensured to prevent material leakage.
Temperature: Stellite alloy has good high temperature resistance and can withstand the heat generated by the high-speed flow and shearing of the material during the homogenization process. It will not affect the sealing performance and homogenization effect due to thermal deformation.
3. Homogenizer type and specification
Type: Different types of homogenizers may have different requirements for valve seats. For example, high-pressure homogenizers usually require valve seats with higher strength and sealing performance to withstand high-pressure environments; while high-shear homogenizers pay more attention to the wear resistance and shear resistance of valve seats.
Specifications: Choose valve seats of appropriate size and model according to the specific specifications of the homogenizer, such as flow rate, power, etc. Make sure that the diameter of the valve seat matches the inlet and outlet diameters of the homogenizer to ensure that the material can pass smoothly while meeting the processing capacity requirements of the homogenizer.
4. Service life and cost
In the long run, choosing Stellite Homogenizer can reduce downtime and maintenance costs caused by frequent replacement of valve seats. You only need to clean and inspect them regularly to ensure that their surfaces are free of impurities and damage. It is more economical for companies with large-scale and continuous production.
