Spirax Sarco advanced valve design , full range , the material widely ( bronze, ductile iron , carbon steel, alloy steel, stainless steel and other materials ) , widely used in the temperature range , all products are certified authority . To provide a safety valve meets the requirements of the different standards .In the vacuum station system, in order to prevent the rated pressure relief valve downstream pressure is higher than the equipment operation , valves must be installed downstream of the valve . Pressure relief valve must be set within the maximum allowable operating pressure range of the device between the normal operating pressure and there is enough pressure to prevent the valve sealing surface damage resulting in frequent jump . Relief valve setting must be performed by qualified personnel. When the safety valve selection should guarantee the safety valve set pressure through the valve can flow through the maximum flow .The following parameters:1 , system or equipment must displacement and the proposed number of valves installed .2, the opening pressure ( or set pressure )3 , and the proportion of medium (liquid medium ) or molecular weight and compressibility factor ( for gaseous media )4, the valve inlet medium temperature5 , if there is back pressure , if any, is the number6 , requires valve performance standards ( eg no special specified , specified by the supplier 英國斯派莎克SV60閥中文版介紹： 英國斯派莎克SV604全行程閥，法蘭連接，適用于蒸汽、不起化學(xué)作用的工業(yè)氣體和水系統(tǒng)的應(yīng)用。
