2PC ISO5211 High Platform Flanged Ball Valve：
Many pipeline system integrators, chemical plant engineers and water treatment project contractors share the same trouble when upgrading manual valves to automatic control: ordinary flanged ball valves lack standard top mounting bases, extra customized adapter brackets are required to match electric or pneumatic actuators, which extends construction cycle and raises procurement cost.This 2-piece high platform flanged ball valve solves this problem fundamentally. Equipped with ISO5211 unified high mounting platform, it can directly install actuators without transition parts. End users who have deployed this valve on steam, purified water, edible liquid and light corrosive medium pipelines feedback that its zero leakage PTFE seat and wide temperature range (-29℃~300℃) greatly cut down post-operation maintenance frequency. It supports PN1.6, PN2.5, PN4.0 three pressure grades, covering most industrial fluid cut-off working conditions.
All valves are manufactured, sized, connected and inspected strictly following national unified industrial standards, which are recognized by global industrial purchasers for export certification and third-party testing:
• Design & Manufacturing Standard: GB/T12237
• Face-to-Face Dimension Standard: GB/T12221
• Flange Connection Standard: JB/T79-2015, HG/T20592
• Pressure Inspection Standard: GB/T26480
Our factory owns complete casting, CNC machining, polishing and pressure testing production lines, every finished valve passes shell strength test and high-pressure tightness test before delivery, test reports can be provided for customs clearance and project bidding.
We offer 4 mainstream body material combinations to match different medium corrosion resistance demand, all spare parts adopt standardized industrial raw materials with traceable material certificates:
Clear Structural Dimension Definition
L: Overall face-to-face length of valve body, unified according GB/T12221
H: Total height of full valve
A: Height of ISO5211 top mounting platform
Φd: Outer diameter of flange; Φd1: Flange sealing surface diameter; Φd2: Flow bore inner diameter
n-Φh: Flange bolt quantity & bolt hole diameter
T: Flange thickness; f: Sealing surface projection height
The split 2-piece body design allows quick disassembly for seat replacement, reducing maintenance downtime.
Standard Pressure & Temperature Performance
DataThree pressure classes are available, all test pressure values are executed per GB/T26480 inspection standard:
1. ISO5211 Standard High PlatformUniversal international mounting interface, match all mainstream electric/pneumatic actuators on market, no custom brackets needed, lower automation renovation cost.
2. Anti-Blowout Valve Stem Safety DesignMulti-layer flexible graphite packing + limit anti-ejection structure, prevent medium leakage under high pressure steam working condition.
3. Full Port Flow ChannelSmooth straight-through bore, low flow resistance, no medium residue, suitable for viscous and edible liquid pipeline.
4. Strict Double Pressure TestEvery finished valve undergoes shell strength test + seat tightness test, zero leakage qualified rate reaches 100% before shipment.
5. Wide Material & Pressure CustomizationCarbon steel / stainless steel body optional, PN16/PN25/PN40 three pressure grades support OEM custom logo and special sealing material.
