Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of automatic exhaust valves, it is recommended to prioritize confirming key technical parameters such as nominal diameter, pressure rating, and applicable medium temperature to ensure compatibility with existing pipeline systems.
  • When deploying automatic exhaust valves in HVAC or industrial fluid systems, the valve body material (such as brass or stainless steel) should be selected based on the maximum working pressure of the system to meet the corrosion resistance requirements of different scenarios.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support to balance procurement risks and long-term cooperation stability.
  • For application scenarios such as high-rise buildings or long-distance water pipelines, it is recommended to choose automatic exhaust valves with dual exhaust structures to improve gas emission efficiency and reduce the risk of water hammer effect.
