The stem axis of the J41W stainless steel flanged globe valve is perpendicular to the seat sealing face. Stem opening or closing stroke is relatively short, and the J41W globe valve has reliable shutoff action, making the valve suitable for medium shutoff or adjustment and throttling. Once J41W series stainless steel valve is fully open, it will no longer have a contact between the seat and clapper sealing surfaces, and thus its sealing surface mechanical wear and tear is small, because most of the cut-off valve seat and valve disc is easy to repair or replace the whole valve sealing components without removed from the pipeline, for valves and pipeline welding into one occasion is very applicable. The flow direction of the medium through this type of valve has changed, so the flow resistance of the globe valve is higher than other valves.
Instructions for ordering:
1. If there is no selected model, please provide detailed parameters, such as medium, temperature, pressure, caliber, material, etc., and our technicians will select the model for you
Ii. If the selected model is available, please provide it according to the selected model
Non-standard products shall be provided with samples or confirmed by drawings
Note: the information is for reference only, or may not be complete, so we apologize for any inconvenience caused to you. The company can be selected according to different requirements and parameters. The company has various sizes of caliber, pressure, different materials, connection mode, drive mode, to meet different needs of various types of gate valves. Please contact 021-6651 8677 or consult online.
Designed and manufactured according to gb12235-89
The length of the structure is gb12221-89
Flange dimensions are JB/ g79-94
Valve inspection and test according to GB13927
1, stainless steel globe valve structure is simpler than gate valve, manufacturing and maintenance are more convenient.
2, the sealing surface is not easy to wear and scratch, good sealing, open and close when there is no relative sliding between the valve disc and the sealing surface of the body, so the wear and scratch are not serious, good sealing performance, long service life.
3, open and close, the disc travel is small, so the height of the globe valve is smaller than the gate valve, but the length of the structure is longer than the gate valve.
4, opening and closing torque, opening and closing more effort, opening and closing time principal.
5, fluid resistance, because the medium channel in the valve body is more tortuous, fluid resistance, power consumption.
6. Medium flow direction: when the nominal pressure PN is less than 16MPa, the medium is generally downstream, and the medium is upstream from the lower direction of the disc; When the nominal pressure PN≥20MPa, the general use of reverse flow, medium from the direction of the disc flow, to increase the sealing element energy. In use, the globe valve media can only flow in one direction, can not change the flow direction.
7. When J41W globe valve is fully open, the disc is often eroded.
