Product DescriptionBellows Seal Globe Valve Straight Cast Steel Globe Valve Water High Temperature and High Pressure Steam Boiler ValveProduct DescriptionBellows Seal Globe ValveA bellows seal globe valve is a linear motion control valve primarily used for regulating, starting, and stopping fluid flow in pipelines. Unlike conventional globe valves, it includes a metal bellows element that acts as a dynamic and flexible seal around the valve stem. This unique design prevents the escape of process fluid into the environment—an essential feature for handling toxic, flammable, or radioactive substances.The globe valve's design allows for precise flow control, and its robust construction ensures long-term operation even in extreme temperature or pressure environments. These valves are also a solution to the long-standing issue of stem leakage in industrial valves, which not only poses safety hazards but also violates environmental and emission regulations.1. Bellows Seal Construction: The bellows is welded at one end to the valve stem and at the other end to the valve bonnet. This creates a hermetically sealed chamber, isolating the stem from the process medium. 2. Double-Seal System Primary Seal: The bellows itself. Secondary Seal: Traditional gland packing, which acts as a backup in the event of bellows failure.3. Valve Operation: Turning the handwheel or activating the actuator moves the stem and disc vertically. As the stem moves, the bellows flexes accordingly while maintaining the seal. 4. Leak Prevention: If the bellows ruptures, the backup packing prevents immediate leakage, allowing maintenance crews time to shut down the system safely.Technical SpecificationsModel NO.RSTV GLVActuatorManualManualCarbon SteelStructureY-Global Globe ValveSealing FormGland Packings Globe ValveStem Thread PositionOutside Screw Stem Globe ValveStandardDIN, GB, ANSI, JISConnection EndsFlange & WeldingSealPTFE/Rptfe/PplWorking PressurePn16~Pn64MOQ1Warranty18 MonthsDelivery Time15~20 DaysAdvantageOEM/ODM Is ApplicableWorking Temperature-196~450oCTransport PackageStandard Plywood CaseSpecification1 1/2′′-36′′(Dn40-Dn900)TrademarkDEYIHS CodeChinaHS Code7307920000Packing & DeliveryCompany ProfileFAQ
