– Model: 61002283 Proportional Pressure Reducing Valve
– Material: High-strength precision alloy (304 stainless steel), treated with aging and surface nitriding for corrosion protection, with a hardness of HB200-230. It is wear-resistant, corrosion-resistant, high-pressure resistant, fatigue-resistant, and not prone to jamming, deformation, or rusting. It is suitable for various media scenarios.
The 61002283 proportional pressure reducing valve is independently developed and adapted by Sany. It is precisely suited to the complex construction conditions of engineering machinery, such as high pressure, high frequency proportional adjustment, and high dust. It effectively solves the industry pain points of traditional pressure reducing valves, such as fixed pressure reduction ratio, large adjustment deviation, slow response, and sealing leakage. As the core pressure reducing and regulating component of the hydraulic system, it uses the difference in cross-sectional area between the two ends of the piston inside the valve body to achieve proportional pressure control. It reduces both dynamic and static pressure, directly ensuring the pressure stability of the equipment’s hydraulic system and avoiding high pressure impact damage to related components. Its adaptability and durability are outstanding.
