  • 500 pounds per square inch (gauge) (psig) for cold working pressure (CWP) and 250 psig for steam working pressure (SWP)
  • Bolted bonnet for reduced risk of leakage
  • Flanged connections for bolting to pipes

Product Description

This class 125 Apollo 721F series inline cast iron globe valve has a bolted bonnet, rising stem, cast bronze seat, and flanged connections, and is used to control flow (throttling) in a pipeline or water plumbing system. The valve body is constructed of cast iron for strength and corrosion resistance, and has a cast bronze seat. The valve’s maximum pressure is 500 pounds per square inch (gauge) (psig) for cold working pressure (CWP) and 250 psig for steam working pressure (SWP). It has a bolted bonnet for tight assembly and reduced risk of leakage, and flanged connections for bolting to pipes and greater ease of installation than welded connections. This class 250 valve meets standard Manufacturers Standardization Society (MSS) SP-85 for quality assurance. 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.

Conbraco Industries, Inc. manufactures ball, mixing, and relief valves, actuators, water gauges, marine fittings, heating and plumbing products, and backflow prevention devices under the Apollo Valve brand. The company, founded in 1928 and headquartered in Matthews, NC, meets international standard ISO/IEC 17025:2005 and makes products that meet International Organization for Standardization (ISO) and American National Standards Institute (ANSI) standards.
