Packing change

Saval's design allows replacement of the packing without the need to isolate the valve and avoid shutting down a production line or pressure in a piping system.
See the following instructions for replacing the packing:
  • 1

    Open the valve fully so that the valve is in the upper position.

  • 2

    Loosen the bolts on the sides of the cable gland and remove it.

  • 3

    Remove the gasket using the appropriate tool.

  • 4

    Prepare new packing material by cutting this mitre.

  • 5

    Fit successive turns of packing ensuring that the cuts are positioned at 90° on the successive turns.

  • 6

    Replace the cable gland.
