Sets of pure expanded mineral graphite rings ( 99.9%) combined with MG-420 packing rings at each end give improved valve sealing over a wide range of pressures and temperatures. A range of grades is available: industrial, nuclear (in both cases, with and without corrosion inhibitor GRAFOIL ®GTK, GTJ.) with a variety of sections and densities. These sets give high value to valve manufacturers.

ECOGRAFLEX VALVE STEM SEALING SYSTEM FOR LOW FUGITIVE EMISIONS
Ecograflex sets are die formed rings sets made of pure mineral graphite rings from pure exfoliated tape with corrosion inhibitor, combining 3 different packings giving 3 types of sealing system sets.
Ecograflex´s geometry and density design have been developed to solve fugitive emissions problems, on a wide range of chemical products, even with fire safe restrictions and in cryogenic conditions.

Ecograflex 420 combines GRAFOIL shaped rings with MG 420 rings to offer low fugitive emission service at high pressures.
Ecograflex 780R combines GRAFOIL shaped rings with MG 780 R rings to give low emissions service in cryogenic and high temperature conditions (fire safe test certified packing as per API 589:607).
Ecograflex 250 combines GRAFOIL shaped rings with MF 250 rings for use on difficult chemical service such as alkylation.
