Cast Steel Angle-Type Globe Valve J44H-16C

Product Description

The closing member of the J44H Angle-Type Globe Valve is a plug-shaped disc with a flat or conical sealing surface. The disc moves in a straight line along the centerline of the fluid flow. Angle-type globe valves are also known as angle valves. The valve stem operates in two modes: the lifting-only type (where the valve stem moves up and down but the handwheel remains stationary) and the lifting-and-rotating type (where the handwheel rotates and moves up and down with the valve stem, and the nut is mounted on the valve body). Angle-type globe valves are only suitable for fully open and fully closed positions; they must not be used for regulation or throttling. Globe valves are of the forced-seal type; therefore, when the valve is closed, pressure must be applied to the disc to ensure that the sealing surfaces do not leak. When the medium enters the valve from below the disc, the operating force must overcome the resistance caused by friction between the valve stem and the packing, as well as the thrust generated by the medium’s pressure. The force required to close a “angle-type globe valve” is greater than that required to open it; therefore, the valve stem must have a larger diameter. Otherwise, the valve stem may bend.

Scope of Application

The angle-type globe valve is a commonly used shut-off valve primarily designed to open or close the flow of media in a pipeline; it is generally not used for flow regulation. Globe valves are suitable for a wide range of pressures and temperatures, but are typically used in medium- and small-diameter pipelines and are suitable for media such as water, steam, oil, etc. at temperatures up to 250℃.
