How to install and operate the valve

  • The buried fire hydrant is installed in ponds with appropriate valves, completely level and vertically.
  • The valve, shaft, and wrench for the valve are designed to be easily opened and closed by an ordinary person. Therefore, the use of any inappropriate tools or excessive force to open and close the valve should be strictly avoided.
  • The wrench closes the valve in a clockwise direction and opens it in a counterclockwise direction.
  • After each use of the valve and ensuring that it is completely closed, be sure to replace the valve outlet cap.
  • Use standard hose ends that match the valve outlet.
  • In order to maintain safety, care should be taken to ensure that the septic tank is located in a suitable location and basin, away from other installation equipment, especially power transmission cables, and protected from any foreign materials, especially water, spilling into the tank.
  • As soon as any valve accessories, such as chain caps, etc., are missing, take steps to secure and reinstall them.
  • Use a suitable strainer to prevent foreign objects from entering the pipeline and valve.
  • Use a suitable sealing washer and standard bolts and nuts to connect the valve flange.
  • To prevent damage to the valve, it is essential to store it in a covered and suitable location before installation. In addition, use appropriate equipment to move the valve and avoid throwing it.
