ANSI Class 150 flanged globe valve, also known as stop valve, is usually made of stainless steel or carbon steel, most of which are operated by manual handwheels. Large ones can also be changed to bevel gear operation, saving the force required for switching.
China Class 150 Flanged Globe Valve Manufacturer
We are American standard globe valve manufacturer located in China, we have advanced factory and high quality globe valve
The valve body is barrel-shaped or streamlined, with beautiful appearance, the flow channel shape is straight-through, and the fluid resistance is small. The closing part (valve disc) and the valve seat are sealed by conical surface, with small closing force, erosion resistance and reliable sealing. The valve seat can be a replaceable valve seat, which can be combined with the material of the sealing surface of the closing part in any combination to meet the requirements of various working conditions and prolong the service life.

Class 150 Stop Valve/Class 150 Globe Valve
Class 150 Stop Valve/Class 150 Globe Valve opening and closing parts of the globe valve are plug-shaped discs, the top of the seal is a plane or a sea cone surface, and the disc moves linearly along the center line of the valve seat. The movement form of the valve stem, there are also lifting and rotating rod types, which can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. Therefore, this type of shut-off globe valve is very suitable for shut-off or regulation and throttling. Because the valve stem of this type of valve has a relatively short opening or closing stroke, and has a very reliable cut-off function, and because the change of the valve seat port is proportional to the stroke of the valve disc, it is very suitable for flow regulation.
Frequently Asked Questions
Can I use this Class 150 globe valve for flow regulation as well as shutoff?
The page discusses shutoff and throttling service. If flow regulation is required, provide the operating flow range, inlet and outlet pressure and temperature and confirm that the selected valve and trim suit the duty. Do not treat the general globe-valve description as a guarantee of a particular control performance.
Which flow direction should I confirm before installing this globe valve?
Request the permitted flow direction for the exact valve configuration and follow the approved installation instructions. Include the intended piping arrangement and operating conditions in the review rather than assuming one direction applies to every globe-valve design.
Should I order handwheel or bevel-gear operation?
The page describes manual handwheel operation and bevel-gear alternatives. Confirm the selected valve size, required operating torque and available access space before choosing the operating arrangement. The order should identify the actual configuration required.
