Product DescriptionIntroductionAdvantages of German - Standard Cast Iron Globe Valves? Good Sealing Performance: The sealing surface is overlay - welded with Co - based hard alloy, which has excellent wear - resistance, corrosion - resistance and anti - friction properties, resulting in a long service life. The double - bellows sealing design (bellows + packing) ensures zero leakage of the valve stem, complies with international sealing standards, avoids fluid loss, and improves the safety of factory equipment.? Structural and Technological Advantages: The structure is relatively simple, with good manufacturability, facilitating maintenance. The friction force between the valve disc and the valve body sealing surface is small, so it is wear - resistant. The opening height is generally only 1/4 of the diameter of the valve seat passage, and the stroke is short.? Wide Application Range: There are various driving methods to choose from, such as manual, gear - driven, electric, and pneumatic. It can be applied to a variety of media and is suitable for numerous industries including petrochemical, chemical fiber textile, plastic paper - making, power and steel industries, as well as pipelines with media such as water, steam, oil products, nitric acid, and acetic acid. It has a relatively wide applicable temperature range, generally able to work in an environment of about - 20℃ - 450℃.? High Cost - performance Ratio: The cost of cast iron material is relatively low, and it has a good cost - performance ratio when certain usage requirements are met. Disadvantages of German - Standard Cast Iron Globe Valves ? High Flow Resistance: When the fluid passes through the valve, due to the structure of the valve disc and other reasons, a relatively large resistance will be generated, which affects the circulation efficiency of the medium and increases energy consumption.? Limited Regulating Performance: It is usually more suitable for fully - open or fully - closed working conditions and is generally not used for fine - tuning the flow rate (although it can be customized in some cases). SpecificationApplicationsBasic SpecificationsSize: Usually ranges from NPS 2" to 16", with different nominal diameters to choose from according to specific pipeline sizes.Pressure Class: Common pressure classes are Class 150 - 600. Different pressure classes are applicable to pipeline systems with different pressure requirements.Material1: The valve body, bonnet, gate, and stem are made of stainless steel materials such as 304, 316, and 316L. The seat sealing surface is made of PTFE, stainless steel + hard alloy, or hard - alloy - welded materials. Packing materials are generally hard alloy, PTFE, asbestos - graphite, or flexible graphite.End Connection: Flange connection is adopted, and various domestic and foreign piping flange standards and flange sealing surface types can be used to meet different engineering needs and user requirements.After Sales ServiceStandard Warranty: 12 months or 2,000 operating hours (whichever comes first).Extended Warranty: Optional coverage up to 36 months.Global Support: 24/7 technical assistance and spare parts supply.Training: On-site or remote operation/maintenance training.Company ProfileWhy Choose Us?OEM/ODM capabilitiesCompetitive pricing & bulk discountsFast shipping & customs clearance supportTurnkey project solutionsFAQQ: What’s the lead time for orders?A: Standard models ship in 15–30 days; customized units require 30–45 days.Q: Do you provide after-sales service overseas?A: Yes, we have partnered service centers in key regions.Q: Can I request a customized bucket size?A: Absolutely!
