Instructions for use:

  • When storing gate valves in storage, their sealing slide should be fully open.
  • The environmental conditions of the warehouse to increase the lifespan of the product and rubber parts should be as follows:
    • Ambient temperature maximum 60 degrees Celsius
    • Maximum ambient humidity 70%
    • Away from direct sunlight
  • Due to corrosion and oxidation of the product in case of discoloration, care must be taken during transportation to prevent impact.
  • When transporting and unloading from the machine, avoid throwing or impacting it, as this will damage the axle rod and the product’s color.
  • Never lift the valve using its handle.
  • Before installing the valve, the pipe path must be cleaned of any dirt and debris such as gravel, wood particles, bolts, etc. If there is a possibility of such objects entering the pipeline, a strainer must be installed in the path of the valve.
  • When closing the valve, make sure that there is no tension in the connection. If the valve is connected via a flange, the corresponding screws should be tightened crosswise.
