2PC Stainless Steel High Platform Flanged Ball Valve DN150 

Large pipeline engineering contractors and factory fluid system managers often struggle with large-diameter cut-off valve selection. Most DN150 ball valves on the market either lack ISO5211 standard top platform, making later automatic transformation impossible; or adopt thin-wall casting, which deforms and leaks easily under long-time PN16 pressure delivery of steam, wastewater and chemical dilute liquid.This DN150 flanged ball valve solves these two core pain points. The valve body is thickened CF8 stainless steel casting, with ISO5211 unified high mounting platform reserved on the top. Clients who equipped this valve in chemical production lines, municipal water supply pipelines and food brewing workshops shared that the full-port straight flow channel brings small flow resistance and no medium sediment. Even after years of continuous operation within -29℃~300℃ temperature range, the PTFE soft sealing seat still maintains zero leakage performance. The two-piece split body design also lets maintenance staff replace sealing parts without removing the whole valve from large pipelines, greatly cutting equipment downtime loss.

 

All specifications of this DN150 flanged ball valve strictly implement complete Chinese industrial standards, which can pass third-party testing and meet export customs document review requirements: • Design & Manufacturing Standard: GB/T12237 • Valve Face-to-Face Length Standard: GB/T12221 • Flange Connection Standard: JB/T79-2015, HG/T20592 • Hydraulic & Air Tight Inspection Standard: GB/T26480Our factory has independent casting, CNC machining, polishing and pressure test production lines. Each DN150 finished valve will complete shell strength test and high-pressure sealing test before delivery, formal test reports and material certificates can be provided for overseas project bidding and customs clearance.

Multiple material collocations are available to match different medium corrosion resistance and temperature demand, all raw materials have traceable quality documents:

• L: Overall flange-to-flange length of valve body, unified in accordance with GB/T12221

• H: Total overall height of complete ball valve

• A: Mounting height of ISO5211 standard top platform

• Φd: Outer diameter of flange; Φd1: Flange sealing surface diameter; Φd2: Full straight through port inner diameter

• n-Φh: Quantity of flange bolts & bolt hole diameter

• T: Flange thickness; f: Height of flange sealing surface bossThe full-port large flow channel design of DN150 model effectively reduces fluid flow resistance, avoids material accumulation, and is suitable for large-flow medium transportation. The multi-layer flexible graphite packing plus limit anti-blowout stem structure prevents medium ejection under high temperature and high pressure steam working conditions. Two-piece split body design realizes on-site disassembly maintenance without pipeline cutting.

Three pressure grades can be customized, all test pressure data strictly implemented per GB/T26480 inspection standard:

1. Municipal Water Supply & Drainage ProjectsMain pipeline cut-off valve for urban tap water, sewage treatment plants, reclaimed water reuse pipe networks; large DN150 flow channel meets large-volume water transportation demand, stainless steel material avoids secondary water pollution.

2. Chemical & Petrochemical IndustryProduction pipeline cut-off for dilute acid, dilute alkali, low-corrosion chemical solvent delivery; thickened stainless steel casting resists medium corrosion, wide temperature range adapts hot steam heating pipelines.

3. Food, Beverage & Brewing IndustryCut-off control of fruit juice, wine, edible syrup, purified water conveying pipelines; CF8/316 stainless steel material complies with food-grade contact standard, no chemical reaction with edible fluid.

4. Thermal Power & Heating SystemMain pipeline switch valve for factory heating steam, boiler auxiliary pipeline; anti-blowout stem and graphite packing eliminate high-temperature steam leakage risk.

5. Industrial Automatic Pipeline TransformationThe reserved ISO5211 high platform can directly match electric/pneumatic actuators, suitable for large-diameter automatic fluid control projects in new factories and old workshop renovation. 

1. Thickened Stainless Steel Cast Body for DN150 Large DiameterThe DN150 valve body adopts thick-wall CF8 stainless steel casting, no deformation under long-time PN16-PN4.0 pressure, stronger pressure bearing capacity than thin-wall cast ball valves of the same caliber.

2. Manual & Automatic Dual-purpose Universal DesignCan be equipped with stainless steel hand lever for manual operation at present; ISO5211 standard platform reserves space for later installation of electric/pneumatic actuators, no need to replace the whole valve during pipeline upgrade.

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 under rated working pressure.

4. Split Two-piece Body for Easy Large Pipeline MaintenanceOnly loosen connecting bolts to split the valve body, operators can replace worn sealing parts on site without cutting the large DN150 pipeline, greatly reducing maintenance cost and downtime.

5. Customization Support & Complete Specification CoverageSupport OEM logo printing, customized pressure grade and special high-temperature sealing material; our product line covers DN15-DN150 full size to match different pipeline calibers.
