Long into the Valve Co., Ltd. Zhejiang is a professional manufacturer of steam traps, steam traps is the basic role of the condensate in the steam system, air and carbon dioxide emissions as soon as possible; while maximizing automatically to prevent steam leakage. Many kinds of traps, each with different performance. Use traps, the first of its features should be selected to meet the best run of steam heating equipment before considering other objective criteria, so choose what you need is the correct and effective trap. Working pressure: the trap inlet pressure and outlet pressure (back pressure) the pressure difference. If the outlet is the atmosphere, back pressure is zero; if the pressure fluctuations, the maximum pressure difference should be taken. (2) Maximum displacement: should have access to the condensation of water vapor device multiplied by the reserve factor. Reserve coefficient generally take 2 to 4 (drum drying equipment, spare factor of 6 to 10).
