DN600 Two-Piece Flanged PTFE Butterfly Valve with WCB Body & Gear Operated

Introduction：

Tianjin Worlds Valve Co., Ltd. presents a Two-Piece Flanged Butterfly Valve engineered for demanding applications requiring exceptional chemical resistance and reliable shut-off. This valve features a PTFE seat and a stainless steel disc fully encapsulated with PTFE (polytetrafluoroethylene) , creating a complete fluoropolymer barrier that isolates all wetted metal components from the process media.

The valve body is manufactured from WCB (cast carbon steel) , offering good mechanical strength for industrial service. The two-piece body construction allows for easy disassembly, simplifying maintenance, seat replacement, and inspection without removing the entire valve from the pipeline. Operation is controlled by a worm gear operator (turbine head) , providing smooth, high-torque manual control suitable for valves up to DN600.

Available in sizes up to DN600, this valve is designed for corrosive media handling in chemical processing, pharmaceutical manufacturing, and other industries where media purity and equipment longevity are critical. Pressure ratings and flange standards are customizable to meet specific project requirements, with common options including PN10, PN16, and Class 150.

As a trusted China-based OEM manufacturer, we offer flexible customization and international certifications to meet your project specifications.

Key Features & Advantages:

1. PTFE Lined Disc & PTFE Seat for Full Chemical Resistance

• Complete Media Isolation: The stainless steel disc is fully encapsulated with PTFE, creating a seamless, non-porous barrier that prevents any contact between the process media and the metal substrate, eliminating corrosion risk.

• Chemically Inert PTFE Seat: The PTFE seat provides exceptional resistance to a wide range of aggressive chemicals, including strong acids, bases, solvents, and oxidizing agents.

• Non-Stick Surface: PTFE’s low-friction, non-stick properties prevent media adhesion and scale buildup, ensuring consistent performance and easy cleaning in high-purity applications.

2. Two-Piece Body Construction for Easy Maintenance

• Simplified Disassembly: The two-piece design allows the valve to be opened for inspection, cleaning, or seat replacement without removing the valve from the pipeline.

• Reduced Downtime: Quick access to internal components minimizes maintenance time in critical process lines.

• Extended Service Life: The ability to service the valve without pipeline disruption simplifies spare parts management and extends overall system life.

3. Worm Gear Operation for High-Torque Control

• Smooth, Effortless Operation: The gear operator provides significant mechanical advantage, making manual operation of larger valves (up to DN600) smooth and manageable.

• Self-Locking Mechanism: The worm gear design holds the disc securely in any position without creeping, ensuring stable flow regulation.

• Clear Position Indication: The gear operator includes a visual position indicator for quick, at-a-glance valve status verification.

4. Robust WCB Carbon Steel Construction

• High-Strength Material: The valve body is cast from WCB (ASTM A216 Grade WCB) , offering good mechanical properties and weldability for industrial applications.

• Durable Exterior Coating: Standard exterior coating protects against atmospheric corrosion; optional coatings are available for harsh environments.

• Secure Flanged Connections: Integral flanged ends provide a rigid, leak-proof connection to the pipeline, suitable for permanent installations.

5. Customizable Specifications for Project Flexibility

• Pressure Ratings: Available in PN10, PN16, Class 150, and other ratings as specified.

• Flange Standards: Conform to EN 1092, ANSI B16.5, AS2129, or other international standards.

• Size Range: Available from smaller diameters up to DN600, accommodating a wide range of pipeline requirements.

• Actuation Options: Can be fitted with electric or pneumatic actuators for automated control.
