APPLICATION

  • Water treatment plant
  • Water source project
  • Building Services
  • Municipal facilities
  • Power & Utility

INSTALLATION INSTRUCTIONS

  • The valve's rated parameters should match the equipment's.Make sure that the valve's rated flow satisfies the actual demand.
  • The installer must be trained or experienced so as to operate the installation correctly.
  • Water supply pipe network should be washed before pressure reducing valve installation, eliminating sand, graval and other debris in the pipe;
  • The flow direction from Inlet to outlet should be paid attention to in installation, and maintenance space around the valve is convenient to assemble;
  • For the size below DN150, the main valve can be installed horizontally or vertically, but horizontal installation is better. the size aboveDN150 only can be installed horizontaly.
  • After debugging, the pilot valve and the needle type flow valve must be locked with locknut;
  • Valve should be checked regularly, ensuring the debris in filter being cleaned.
