Physical Data

Post Indicator Valve - Flanged - PIF

Materials List


  • Piping systems and valves should be thoroughly cleaned and free from ingress of foreign materials.
  • Visually inspect the valve seating and ports for cleanliness immediately prior to installation.
  • All valves should be independently supported against movement and stress from the connected piping system.
  • Ensure that the valve pressure rating is compatible with service conditions.
  • Operate the valve at least once from the open to closed position.
  • Gate valves are not suitable for throttling applications.
  • Gate valves should be installed in the vertical position on horizontal pipework and in the horizontal position on vertical pipework.
  • See indicator post datashet for further installation instructions.

Inspection and Maintenance

  • Valves should be inspected periodically and should be cycled to prevent buildup of foreign materials in the piping system and valve body.


Gate valves are manually operated multi-turn valves and are opened by a handwheel or other operating device, generally in a counter clockwise direction and then closed clockwise
