2PC CF8 Stainless Steel ISO5211 High Platform Flanged Ball Valve

luid system contractors and factory process engineers often face two core headaches when upgrading pipeline control equipment. Many low-cost flanged ball valves on the market only reserve space for manual handles, without a unified ISO5211 top mounting base. If factories plan to realize automatic remote control later, they have to buy extra custom adapter brackets, which pushes up procurement costs and delays construction schedules.In addition, cast iron or thin-wall carbon steel valves used in water treatment, food and light chemical pipelines will rust and leak within a short service cycle after contacting humid, slightly corrosive media. This CF8 stainless steel high platform flanged ball valve solves both problems perfectly. Clients who installed this valve on purified water, beverage, dilute chemical liquid and steam pipelines share that the integrated ISO5211 platform supports direct assembly of electric and pneumatic actuators without modification. The thickened stainless steel casting body resists rust and corrosion stably, and the split two-piece design lets maintenance workers replace worn PTFE seats without removing the whole valve from the pipeline, greatly cutting downtime losses.

 

This stainless steel flanged ball valve follows complete domestic industrial standards covering design, dimension, flange connection and delivery inspection, all standards are recognized by third-party testing institutions and export customs authorities: • Design & Manufacturing Standard: GB/T12237 • Valve Face-to-Face Length Standard: GB/T12221 • Flange Connection Specification: JB/T79-2015, HG/T20592 • Hydrostatic & Air Tightness Inspection Standard: GB/T26480Our factory owns full production workshops including precision casting, CNC machining, mirror polishing and pressure testing. Every finished valve undergoes shell strength test and high-pressure sealing test before shipment. Formal material certificates and test reports can be provided for overseas project bidding and customs clearance.  

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

L: Overall flange-to-flange length of valve body, unified according to GB/T12221
H: Total overall height of the complete ball valve
A: Mounting height of ISO5211 standard top high platform
Φd: Outer diameter of flange; Φd1: Flange sealing surface diameter; Φd2: Full straight through port inner bore diameter
n-Φh: Quantity of flange bolts & bolt hole diameter
T: Flange thickness; f: Height of flange sealing surface boss

Three pressure grades support customized production, all test pressure data strictly implemented per GB/T26480 inspection rules:

1. Municipal Water Supply & Sewage Treatment ProjectsMain pipeline cut-off valve for urban tap water, sewage treatment plant, reclaimed water reuse pipe networks. CF8 stainless steel material avoids secondary water pollution and effectively resists slight corrosion of sewage medium.

2. Food, Beverage & Pharmaceutical IndustryOn-off control for fruit juice, wine, edible syrup, pharmaceutical purified water conveying pipelines. Stainless steel meets food & medical contact standards, no harmful substance precipitation.

3. Light Chemical & Fine Chemical PlantsCut-off equipment for dilute acid, dilute alkali, low-corrosion chemical solvent delivery pipelines, stainless steel casting delays medium corrosion damage to valve body.

4. Thermal Heating & Boiler Auxiliary SystemsSwitch valve for factory heating steam, boiler auxiliary pipelines. Anti-blowout stem and graphite packing eliminate high-temperature steam leakage risk.

5. Industrial Automatic Pipeline TransformationReserved ISO5211 high platform matches all mainstream electric/pneumatic actuators on market, ideal for new factory automatic fluid control and old workshop pipeline renovation projects.

6. Coastal & Offshore Engineering PipelinesStainless steel body resists salt fog and seawater corrosion, suitable for humid outdoor, coastal marine fluid conveying pipelines.

Core Trustworthy Product Advantages

1. Integrated ISO5211 Standard High Mounting PlatformUniversal international installation interface, support direct installation of electric/pneumatic actuators without custom transition brackets, compatible with global mainstream actuator brands, save later automation transformation cost.

2. Thickened CF8 Stainless Steel Cast BodyStable rust-proof and anti-corrosion performance, service life far longer than cast iron and thin-wall carbon steel valves under humid and slightly corrosive medium conditions.

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 On-Site MaintenanceOnly loosen connecting bolts to split valve body, maintenance staff can replace worn sealing parts without cutting pipeline, reduce equipment downtime and maintenance labor 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.
