1. Strong Corrosion Resistance
   Made of 304, 316 stainless steel, the passivation film on the surface resists water, acids, alkalis, salts, and corrosive media, suitable for corrosive environments in chemical, pharmaceutical, and food industries.
2. High Strength and Temperature Resistance
   Operable between -20ºC and 400ºC, with tensile strength over 520MPa, meeting high-pressure and high-temperature requirements (e.g., steam pipelines, high-pressure fluid systems).
3. Excellent Hygienic Properties
   Surface roughness ≤0.8μm, compliant with FDA and 3A standards, preventing medium residue and bacterial growth for food-grade and pharmaceutical fluid control.

 

• Precise Back Pressure Adjustment
  Manual knob or electric adjustment of spring preload enables precise setting between 0.1-10MPa, with adjustment accuracy of ±2%.
• Dynamic Pressure Compensation
  When system flow fluctuates, the disc automatically adjusts the opening to maintain stable outlet pressure (e.g., chromatographic analysis systems, high-pressure infusion pumps).
• Surge Protection
  Prevents pump outlet surge caused by sudden pressure drop, protecting equipment safety (common in centrifugal pumps, compressor systems).
