Pipeline project contractors and municipal water system operation supervisors often run into bottlenecks when sourcing large-diameter shut-off valves. Most DN150 ball valves available on the market either skip the ISO5211 standard top mounting platform, forcing extra custom adapter brackets for later automation upgrades, or adopt thin-wall stainless steel casting that deforms and leaks under long-term PN16 water and weak corrosive medium transport.This DN150 CF8 stainless steel flanged ball valve addresses both pain points simultaneously. End users who installed this valve on municipal water supply trunk pipelines, food factory large-diameter beverage conveying mains and light chemical dilute liquid delivery systems shared that the thickened CF8 stainless steel casting body delivers stable rust and corrosion resistance even under years of continuous operation. The integrated ISO5211 high mounting base supports direct assembly of electric and pneumatic actuators without secondary modification. The two-piece split body design allows maintenance crews to replace worn PTFE seat seals without detaching the entire valve from DN150 large pipelines, cutting unplanned production downtime losses effectively.
This large bore DN150 stainless steel flanged ball valve implements a complete set of domestic industrial standards covering design, structural length, flange connection and factory pressure testing, all standards are recognized by third-party testing institutions and global export customs authorities:
• Hydrostatic & Air Tightness Inspection Standard: GB/T26480Our factory owns full production workshops including precision stainless steel casting, CNC heavy-duty machining, mirror polishing and pressure testing. Every finished DN150 ball valve undergoes shell strength test and high-pressure tightness test before shipment. Complete material certificates, pressure test reports and dimension drawings can be supplied for overseas municipal, chemical and food project bidding and customs clearance filing.
Global Industrial Application Scenarios
1. Municipal Water Supply & Sewage Treatment ProjectsMain pipeline shut-off valve for urban tap water trunk lines, sewage treatment plant main pipelines, reclaimed water reuse pipe networks. Thickened CF8 stainless steel avoids secondary water pollution and resists slight corrosion of sewage medium, matching DN150 large-flow municipal transportation demand.2. Food, Beverage & Brewing Large Production LinesMain pipeline on-off control for fruit juice, wine, edible syrup, purified water conveying mains. Stainless steel material complies with food contact sanitary standards, no harmful substance precipitation, suitable for factory large-volume beverage continuous production.
3. Light Chemical & Fine Chemical Factory Main PipelinesShut-off equipment for dilute acid, dilute alkali, low-corrosion chemical solvent delivery trunk lines, thick stainless steel casting delays medium corrosion damage to valve body under long continuous operation.
4. Thermal Heating & Boiler Auxiliary Main PipelinesSwitch valve for factory heating steam mains, boiler auxiliary large-diameter pipelines. Anti-blowout stem and graphite packing eliminate high-temperature steam leakage risk.
5. Old Factory Large-Diameter Pipeline Automation RenovationReserved ISO5211 high platform matches all mainstream electric/pneumatic actuators on the market, ideal for DN150 large-bore automatic fluid control transformation of aging workshop pipeline systems.
6. Coastal & Offshore Municipal Engineering PipelinesStainless steel valve body resists salt fog and seawater corrosion, suitable for humid coastal urban water supply and marine fluid conveying main pipelines.
Core Trustworthy Product Advantages
1. Thickened CF8 Stainless Steel Cast Body for DN150 Large BoreThe DN150 valve body adopts thick-wall stainless steel casting, stable structural strength under long-term PN16-PN4.0 pressure operation, not easy to deform, far superior to thin-wall stainless steel ball valves of the same caliber.
2. Integrated ISO5211 Standard High Mounting PlatformUniversal international actuator installation interface, support direct assembly of electric/pneumatic actuators without custom transition brackets, save later automatic control transformation investment for large pipeline projects.
3. Zero-Leakage PTFE Soft Sealing SystemPrecision solid ball core cooperates with PTFE/PPL high-temperature resistant valve seat, 100% pass tightness test before delivery, stable sealing without medium leakage under rated working pressure.
4. Split Two-Piece Body for Convenient Large Pipeline MaintenanceOnly loosen connecting bolts to split valve body, maintenance staff can replace worn sealing parts on site without cutting DN150 large pipelines, greatly reduce equipment overhaul downtime and labor maintenance cost.
5. Complete Size & Pressure Customization SupportFull DN range DN15-DN150, PN16/PN25/PN40 three pressure grades available, support OEM logo engraving and customized special high-temperature sealing materials.
