3 General summary Product summary Codification O-ring and diaphragm material Back Close? Codification IMF components (1) The main material means the material of the envelope (external parts) of the component (the body) Generally for a component made of stainless steel, all parts in contact with the media are made of stainless steel and others are made of Nickel plated brass. (2) The function defined the number of ports, the number of positions and the position of the valve (opened or closed) when the valve is not energized. (3) O-ring and diaphragms materials, and cleaning operating procedures are defined into the page O-ring and diaphragms materials. (4) The options define the complementary characteristics: - the "X" digits definition which are not mentioned in the table. - complementary definition of previous digits of the code. The option 1000 called "STANDARD VERSION" defines the basic version of IMF components (without any particularity). Example of codification: D 386 L S 85 N I P 1000 D = Reducer (PCV ) 386 = Type or family L = Brass construction S = Max inlet pressure (MWP) 420 b 85 = Outlet range 0 to 400 bar (as per data sheet) N = O Rings type = Nitrile O-ring / Cleaning procedure P902 I = SS 316L valve insert P = PEEK seat 1000 = Standard version (balanced valve & self venting )
