This class 125 Apollo 121T-LF series inline bronze globe valve has a threaded bonnet, lead-free construction for use with potable water, rising stem, bronze seat, and female National Pipe Taper (NPT) threads on both ends, and is used to control flow (throttling) in a pipeline or water plumbing system. The valve body and seat are constructed of American Society for Testing and Material (ASTM) B62 bronze for strength and corrosion resistance. The valve’s maximum pressure is 200 pounds per square inch (gauge) (psig) for cold working pressure (CWP) and 125 psig for steam working pressure (SWP). It has a threaded bonnet for tight assembly and reduced risk of leakage, and female NPT threads on both ends for connecting to male threaded pipes. This class 125 valve meets standard Manufacturers Standardization Society (MSS) SP-80 for quality assurance and complies with California Assembly Bill AB1953, Vermont Act 193, Maryland HB372, Louisiana HB471 and federal public law 111- S3874, which limit the amount of lead in plumbing fixtures that come in contact with water intended for human consumption. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure. This rising stem globe valve is for use in various pipeline or water plumbing systems.

Globe valves control flow rates in a piping system by the lift of a vertical stem and disk, which must be turned to open and close the valve. A seated disc extends into the center of the valve to act as a plug to restrict or open the flow path, depending on how tightly the valve stem is turned. The stem on globe valves can be either rising (moves up as the valve opens) to indicate if the flow is on or off, or non-rising (stem height remains constant when the valve is either open or closed) for use in small spaces. Globe valves are used in various water, gas, air, and steam piping systems that require frequent throttling operations.
