Allway is a professional China globe valve Manufacturers and China globe valve suppliers. we started globe valve production and sale&wholesale earlier in the year of 2005 and then have been growing gradually towards mature. The staff has grown from 20 to nearly 200 in the past 16 years. we can help customers with pipeline design According to the actual working environment and replacement & maintenance within the warranty period after actual installation.
globe valve ‘s advantages are:
(1) Globe valve structure is simpler than gate valve, manufacturing and maintenance are more convenient.
(2) sealing surface is not easy to wear and scratch, good sealing, no relative sliding between the disc and valve body sealing surface when opening and closing, so wear and scratch are not serious, good sealing performance, long service life.
(3) when opening and closing, the disc stroke is small, so the globe valve height is smaller than the gate valve, but the structure length is longer than the gate valve.
(4) the opening and closing torque is large, the opening and closing is more laborious, and the opening and closing time is principal.
(5) the fluid resistance is large, because the medium channel in the valve body is more tortuous, the fluid resistance is large, and the power consumption is large.
(6) Medium flow direction nominal pressure PN≤16MPa, the general use of downstream, medium from the lower direction of the valve disc;Nominal pressure PN≥20MPa, the general use of countercurrent, medium flow from the direction of the disc.To increase the sealing energy.When used, the globe valve medium can only flow in one direction, can not change the direction of flow.
(7) When fully open, the disc is often eroded.
Stem axis of globe valve is perpendicular to sealing surface of valve seat.Stem opening and closing stroke is relatively short and has very reliable cutting action, making this valve suitable for medium cutting or regulating and throttling use.
globe valve has original design,.exquisite technique,perfect manufacture and complete testing ways, it has passed ISO9001 international quality system certification and has been selling well all over china and exporting to many countries and areas, which are used widely in water supply and drainage, electric power, petrol chemical industrial,metallurgy and other trades.
