    frequently asked questions

    • Q: Is downward piping allowed for the JK20 corrosion-resistant series?

      Yes, downward piping is permitted, but it must comply with the product’s installation specifications. The JK20’s pressure elements (bellows for low pressure, Bourdon tube for high pressure) are designed to withstand vertical downward fluid flow, but improper piping layout may cause accuracy deviations or corrosion acceleration. It is mandatory to follow the "JK20 Installation Manual" for slope and support requirements.
    • Q: What are the key prerequisites for safe downward piping?

    • Q: Can downward piping be used for vacuum or high-pressure (>40MPa) scenarios?

    • Q: What piping materials are compatible with JK20 downward piping?

    • Q: How to design downward piping to prevent medium stagnation?

    • Q: What sealing components are required for downward piping joints?

    • Q:How to avoid cavitation damage in downward piping?

    • Q:Why does the JK20 show inaccurate readings after downward piping installation?

    • Q:Can JK20 be customized for special downward piping needs?
