High Platform Flanged Ball Valve

High Platform Flanged Ball Valve

High Platform Flanged Ball Valve ：

This 2-piece high platform flanged ball valve is manufactured from stainless steel CF8, featuring a full port design, manual lever operation, and ISO5211 standard top mounting platform. It perfectly matches electric/pneumatic actuators without extra conversion brackets, widely used in chemical, water treatment, food, petroleum, and pipeline fluid cut-off control systems. The flanged connection complies with PN16/PN25 pressure standards, with stable sealing, anti-leakage performance, and long service life under corrosive medium working conditions.

Core Advantages

1. ISO5211 Standard High Mounting Platform

Universal actuator matching interface, direct installation of electric/pneumatic actuators, simplified automation pipeline modification, no customized adapter required.

2. Stainless Steel CF8 Body & Ball Core

Excellent acid & alkali corrosion resistance, suitable for weak acid, weak base, edible liquid, purified water media; precision machined solid ball core reduces flow resistance.

3. Two-piece Split Body Structure

Convenient disassembly for internal seat maintenance and replacement, low post-maintenance cost; integral flanged connection, uniform stress distribution during pipeline installation.

PTFE sealing seat achieves zero leakage under nominal pressure, flexible opening & closing with only 90° rotation of the handle.

5. Dual Pressure Grade Support PN16 & PN25

Two pressure specifications optional for different pipeline pressure demands, complete size range DN15-DN100.

Installation Notes

1. Confirm nominal pressure DN size and flange standard before pipeline installation 2. Clean pipeline internal impurities to avoid scratching PTFE sealing seat

3. Valve handle rotation angle is limited to 90°, do not apply excessive torque

4. When assembling actuators, align ISO5211 platform square shaft without forced assembly

5. For high-temperature medium, select reinforced PTFE seat version to extend service life
