      The certificate of the obligatory certification system ГОСТ Р № РОСС RU.AB72.B00460 is issued by the certification authority LLC " Scientific – technical centre " Techno – standard" reg. №РОСС RU.0001.11AB72.       "EZTM" JSC quick-change restriction devices (QCDs) are manufactured under ТУ 3667-013-05744403-2009 of comliance with industrial safety requirements of current normative documents (GOST 12.2132-93). "EZTM" JSC QCDs have a set of advantages over domestic and abroad analogues:

• symmetrical pocket construction in front of the membrane and behind it as well as mechanical treatment of the device in whole ensures the constant flow of gas;
• ease and simplicity of maintenance;
• membrane replacement is carried out during 20 minutes irrespective of nominal bore;
• aperture design for pressure tap ensures condensation flowing at gas of high-humidity transportation;
• availability of apertures for blowing.

      All the QCDs produced at "EZTM" JSC are designed and made taking into account the organization of the full mechanic safety on operation, repair and control. Before shipping to Customer each quick-change restriction device undergoes an intensive control and full acceptance testing on a specialized stand on a special programme under the pressure being 1.5 times larger than the working one.
