PFA Fully Lined Floating Ball Valve

Description

TECHNICAL DATA SHEET

Fully Lined PFA Floating Ball Valve
Series: PN1.0~1.6MPa, Class 150LB

1. PRODUCT OVERVIEW

Fully lined PFA floating ball valve features high-pressure injection/molding PFA (Perfluoroalkoxy) lining applied to carbon steel or stainless steel valve body and ball surface. Designed for on-off control of highly corrosive media, widely used in chemical, pharmaceutical, petroleum refining, metallurgy, electronics, food industries and high-purity applications.

Key Features:

• Zero Leakage Seal: PFA/reinforced PTFE soft seal between ball and seat, achieving bubble-tight sealing under both low and high pressure.
• Full Corrosion Protection: PFA lining covers all wetted parts including body cavity, ball and stem channel – no metal contact with media. Resists “all strong corrosives except molten alkali metals and elemental fluorine”.
• Blow-out Proof Stem: Integrally forged ball and stem design prevents stem ejection under sudden pressure surge.
• Full Bore Design: Smooth, equal diameter flow path minimizes pressure drop and facilitates pipeline pigging/cleaning.

5. DIMENSIONS & CONNECTIONS (PN16 / 150LB)

Unit: mm

Note: For ASME B16.5 Class 150LB dimensions, replace flange dimensions accordingly; L dimension refer to ASME B16.10.

6. PERFORMANCE CURVES & TORQUE DATA

6.1 Pressure-Temperature Rating (PFA Lined)

• Maximum Operating Temperature: 150℃ (continuous service)
• Do not exceed 150℃ for prolonged periods to prevent PFA softening/deformation.

6.2 Operating Torque (Reference @ 25℃ Water)

*Note: For media with high specific gravity, crystalline/corrosive nature or containing particles, apply safety factor 1.2~1.5.*
