2PC Manual ISO5211 High Platform Flanged Ball Valve：
System integrators, chemical plant operators and water treatment project buyers often encounter two common problems during pipeline transformation. First, ordinary manual flanged ball valves lack a standardized top mounting base. If later you want to install electric or pneumatic actuators for automatic control, you need to buy extra custom adapters, which raises extra procurement cost and delays construction progress. Second, many low-cost ball valves adopt thin castings and simple sealing structures, which will leak frequently under long-term steam and weak corrosive medium working conditions, bringing repeated maintenance work to the workshop team.This manual high platform flanged ball valve solves both troubles at once. It reserves the unified ISO5211 mounting platform on the valve top while keeping the convenient hand lever operation for manual control. Clients who have applied this valve to DN15-DN100 water, steam and edible fluid pipelines mention that its CF8 stainless steel body and PTFE soft seal maintain zero leakage stably within -29℃ to 300℃ working temperature, and the split two-piece body makes daily seat replacement much easier without removing the whole valve from pipelines.
The whole valve follows complete national industrial standards in design, dimension, flange connection and factory inspection, all standards are accepted by third-party testing institutions and export customs authorities:
• Design & Manufacturing: GB/T12237
• Face-to-face structural length: GB/T12221
• Flange connection specification: JB/T79-2015, HG/T20592
• Pressure tightness & strength test: GB/T26480We have full production workshops covering casting, CNC machining, surface polishing and hydrostatic test. Every finished valve will go through shell strength test and high-pressure sealing test before delivery, and formal test reports can be provided for bidding and customs clearance.
Multiple material combinations are available to match different medium corrosion resistance requirements, each raw material has traceable material certificate：
| Component Name | Optional Material Options |
|---|---|
| Valve Body & Bonnet | WCB Carbon Steel / CF8(304) / CF8M(316) / CF3M(316L) |
| Ball Core | WCB / CF8 / CF3M |
| Anti-blowout Stem | 2CR13 / F304 / F316L |
| Seat Seal | PTFE / High temp resistant PPL |
| Stem Packing | Flexible Graphite |
| Body Gasket | PTFE Gasket / Metal Spiral Wound Gasket |
| Fasteners (Bolt & Nut) | 35# Carbon Steel / 304 / 316 / 316L Stainless Steel |
| Operating Handle | QT450 Ductile Iron / Cast Stainless Steel |
Internal structure & dimension parameter explanation
• L: Overall flange-to-flange length of valve body, unified per GB/T12221
• H: Total overall height of the complete ball valve
• A: Height of ISO5211 standard top mounting platform
• Φd: Flange outer diameter; Φd1: Flange sealing surface diameter; Φd2: Straight through full port inner bore diameter
• n-Φh: Quantity of flange bolts & diameter of bolt holes
• T: Flange thickness; f: Height of flange sealing surface bossThe full port straight flow channel minimizes fluid resistance, avoids medium residue buildup, which is ideal for beverage, oil and clean water pipelines. The anti-blowout stem structure with multi-layer graphite packing effectively prevents medium ejection under high temperature and high pressure.
