ECOGRAFLEX VALVE RINGS

Formed Valve Sealing Ring Assemblies

Ecograflex is a set of shaped rings, made of pure expanded mineral graphite (99.9%) with a corrosion inhibitor.

It has combined with three different packings , resulting in three different sealing systems for valves with which to solve:

  • Problems of work at cryogenic temperatures
  • Working in high temperature conditions
  • Work with chemical products (acids and alkalis) and environmental regulations such as fugitive emissions or Cl- F-.

The geometry and density of the different rings of these assemblies make Ecograflex a sealing system for valves and equipment that meets the most stringent restrictions of fugitive emissions.

Its shape has been designed to reduce to the maximum friction with the rod .

Available in various references:

  • Ecograflex X 1000 R Combines Grafloil® GTX and MG 1000 R, the new packing that guarantees maximum tightness.
  • Ecograflex 780 R Combines Grafoil® and MG 780R . Minimum gas emission, designed to work in both cryogenic and high temperature services (certified according to the API 589: 607 fire test).
  • Ecograflex 420 Combines Grafoil® and MG 420 for high pressure services, allowing optimal emission control of the equipment.
  • Ecograflex 250 Combination of Grafoil® and MF 250 , special for alkylation and for chemical products.
