Spirax Sarco SV604 full stroke valve, flange connection , suitable for steam , can not afford chemical applications of industrial gases and water systems.

Application

    SV604 safety valve for steam boilers , pipes , compressors and cylinders and other protection application process has been most protective equipment

    SV604 is PN40/AN300, can raise the standard DIN flanges and ANSI standard flanges . Sealing performance meets API527 standards. According to customer requirements to provide a soft seal spool .

    Spirax Sarco SV604 safety valve is widely used in food, beverage , petrochemical , steel, metallurgy , power plants and other fields, is the best choice for pressure vessels and piping equipment overpressure protection .

    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 temperature

5 , if there is back pressure , if any, is the number

6 , requires valve performance standards ( eg no special specified , specified by the supplier
