Product advantages:
1. The spring adopts ni-base alloy x-750, which has good corrosion resistance, seawater resistance and stable torque, and can provide material proof.
2. The spring is treated with solid solution, with high tensile strength of 910MPa, Brinell hardness HB350, high hardness and good fatigue resistance. After heat treatment, the residual deformation stress is eliminated, which greatly improves the service life of the spring.
3. Rubber is treated with special process to avoid rubber aging after high-temperature spraying and give full play to rubber performance.
4. The valve body adopts the casting process of production line, with smooth appearance, clear casting, high dimensional accuracy and guaranteed delivery time.
5. The mechanical properties of the main material fully meet the qt450-10 standard, and the spheroidization rate can reach level 3.
