Flow direction of Globe Valves<\/h2>\r\n\r\n\r\n\r\n\r\nFor applications with low temperatures, Globe valves are normally installed so that the pressure is under the disc. This contributes to an easy operation and helps protect the packing.\r\n\r\n\r\n\r\n\r\n\r\nFor applications with high-temperature steam service, Globe valves are installed so that the pressure is above the disk. Otherwise, the stem will contract upon cooling and tend to lift the disk off the seat.\r\n\r\n\r\n\r\n\r\n
Typical Applications of Globe valves<\/h2>\r\n\r\n\r\n\r\n\r\nThe following are some of the typical applications of Globe valves..\r\n\r\n\r\n\r\n\r\n

China Angle Globe Valve<\/a><\/strong><\/h2>\r\n\r\n\r\n\r\n\r\nThe angle globe valve is a modification of the basic standard pattern globe valve where the ends are at an angle of 90 degrees.\r\n\r\n\r\n\r\n\r\n\r\nA variation on the straight globe valve, angle globe valves\u2019 have a design that encourages the media to flow at a 90\u00b0 angle, thus generating a lesser pressure drop. Preferred for regulating liquid or air media, angle globe valves are also ideal for applications that require pulsating flow due to their superior slugging effect capability.\r\n\r\n\r\n\r\n\r\n\r\nWith over 20 years of production expertise and employing the latest in manufacturing technology, ZECO is your supplier of choice for quality angle globe valves. Production is tailor-made to your specific needs, with 5 production lines completing large-volume orders within 30 days.\r\n\r\n\r\n\r\n\r\n
