VALVE STEM SEALING RING SETS
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 different packings giving 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. NEW Ecograflex X1000R combines GRAFOIL© GTX (Shell MESC SPE 85/203) shaped rings with NEW MG-1000 R packing rings to offer low fugitive emission service at high temperature and pressures. TA LUFT in process ) Ecograflex 420 combines GRAFOIL © shaped rings with MG-420 rings to offer low fugitive emission service at high pressures. Ecograflex 780 R 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 Ç(589:607). Ecograflex 250 combines GRAFOIL© shaped rings with MF-250 rings for use on difficult chemical service such as alkylation.

SET OF RINGS MG 420+EG

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 gradesis available: industrial, nuclear (in both cases, with and without corrosion inhibitor GRAFOIL© GTB, GTJ y GTX marca GRAFTECH © with a variety of sections and densities. These sets give high value to valve manufacturers.
