    Spirax Sarco SV607 whole trip , the whole nozzle valve for steam, air , application role can not afford chemical inert industrial gases and non- hazardous liquids.

Application

SV607 safety valve : the whole trip , the whole nozzle valve . Suitable for the application of steam , air can not afford chemical industrial gases and non- hazardous liquids . For steam or hot water boilers, generators , pressure vessels , gas tank and air compressor , autoclave valve downstream protection.

Diameter DN15 ~ 50, the pressure PN25, BSP or NPT threaded connections DN15 ~ 25 provides for sanitary clamp connections . Sealing performance meets API527 standards. Provides a soft seal spool . SV607/SV604 safety valve : full stroke valve flange connection . Mainly used in steam boiler pipes. Pressure vessels, compressors and cylinders and other protective guard and most of the industrial process equipment.

Comply with the requirements of DIN320 TRD421 with TUV certification , caliber DN20 ~ DN150, SV607 pressure level is PN16/25, SV604 is PN40/AN300, can provide standard flanges and ANSI standards DIN flanges . Sealing performance meets API527 standards. According to customer requirements to provide a soft seal spool .

    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
