Home FAQ
  • Q: After purchasing a Zhongxun valve, if you encounter technical problems during the installation process, can you get professional guidance?
    A: 
    Of course. Zhongxun Pipeline is equipped with an expert team of 4 senior technicians, who can provide free on-site surveys, 3D modeling pre-installation guidance, and solve installation problems in real time through a remote video system to ensure the perfect match between the valve and the pipeline system.
  • Q: When there are quality problems with the product, how does Zhongxun protect the after-sales rights?
    A: 
    The company promises "three guarantees" service (refund/replacement/repair), and provides CNAS certified quality inspection reports based on 9 advanced testing equipment (including German imported penetrants). If it is confirmed to be a product defect, a solution will be issued within 48 hours, and a new device will be replaced free of charge if necessary.
  • Q: Does Zhongxun provide after-sales service for non-standard customized products?
    A: 
    We provide full life cycle service. For customized valves, we establish exclusive digital files, regularly track material changes through direct reading spectrometers, and detect structural integrity through ultrasonic flaw detection to ensure a safe service cycle of more than 10 years.
  • Q: Can Zhongxun provide upgrade and transformation services for old equipment?
    A: 
    Launch the "valve remanufacturing" plan. Use X-ray flaw detection to evaluate the fatigue of the old valve body, use laser cladding technology to repair key components, upgrade sealing materials, and restore the performance of old valves to more than 95% of new products, extending the service life by 3-5 years.
  • Q: How fast is Zhongxun's emergency response under emergency conditions?
    A: 
    Establish a three-level emergency mechanism:

    level 1 response(within 2 hours): Provide electronic drawings and virtual assembly instructions;
    level 2 response(within 24 hours): Technical personnel arrive at the site with spare parts;
    level 3 response(within 72 hours): Coordinate spare valves to ensure production continuity.
