Good News!
Sedelon has produced a big size gate valve for 36 inch 600LB this May. This big-size valve was exported to Iran. This Iran customer has done business with US from 2007. I believe this order for the big-size gate valve will take our business relationship to a higher position.
Congratulations! Sedelon ® Gate Valve has obtained Fugitive Emission certificates. Perfect design, Special facilities and excellenttechnique. Our products have been sold to Taiwan, America, Germany…ect,.
Fugitive Emission Valves are thosevalves which bleed only a small amount of leakage to the external environment.In some European countries, there are customized companies to provide Fugitive Emission Testing Service for the local manufactures and end users.
At present, theFugitive Emission Test Standards of International authority are the following three:EPAmethod21, ISO15848 and SHELLMESCSPE77/312.Among them, EPAmethod21 had detaileddescriptions of rules for the Fugitive Emission Testing Methods. ISO15848 and SHELLMESCSPE77/312 evaluate the performance of the valves in three aspects, such as Tightness Class, Endurance Class and Temperature Class. The classes are evaluated as A, B or C.
