Flanged Butterfly Valve with PTFE Seat And CF8M Disc | Split Body Design

Introduce:

The valve body is available with flanged ends conforming to international standards (EN 1092, ANSI B16.5, AS2129, etc.). The PTFE seat offers exceptional chemical inertness, making it suitable for a wide range of aggressive media including acids, alkalis, solvents, and high-purity fluids. The CF8M disc provides good mechanical strength and pitting resistance, particularly in chloride-containing environments.

Available in sizes from DN50 to DN600, this valve is engineered for chemical processing, pharmaceutical manufacturing, water treatment, and other industrial applications where media purity and corrosion resistance are critical. As a trusted China-based OEM manufacturer, we offer flexible customization of materials, pressure ratings, flange standards, and actuation options to meet specific project requirements.

Tianjin Worlds Valve Co., Ltd. – Your Reliable Source for Durable, Cost-Effective Flow Control

Key Features & Advantages:

1. PTFE Seat for Superior Chemical Resistance

• Chemically Inert: PTFE is resistant to almost all industrial chemicals, including strong acids, bases, solvents, and oxidizing agents.

• Low Friction: The self-lubricating nature of PTFE reduces operating torque and minimizes wear on the disc.

• Wide Temperature Range: Suitable for applications from -35°C to +200°C (depending on pressure and media).

2. CF8M Stainless Steel Disc for Corrosion Resistance

• High-Grade Material: CF8M (AISI 316) offers excellent resistance to pitting, crevice corrosion, and general corrosion in chloride and acidic environments.

• Durable Construction: Provides long service life in demanding industrial services.

3. Two-Piece Body Construction for Easy Maintenance

• Simplified Disassembly: The valve can be opened by removing the body bolts, allowing access to internal components without removing the valve from the pipeline.

• Quick Seat Replacement: Worn PTFE seats can be replaced in the field, reducing downtime and maintenance costs.

• Inspection Friendly: Regular inspection of disc, seat, and stem is straightforward.

4. Flanged Connections for Secure Installation

• Leak-Proof Bolted Joints: Integral flanges provide a rigid, reliable connection to pipeline flanges using gaskets and bolts.

• Standard Compatibility: Flange drilling conforms to EN 1092, ANSI B16.5, or other customer-specified standards.

• Suitable for Dead-End Service: The flanged design allows the valve to be used at pipeline ends without additional support.

5. Wide Size Range and Customization

• Size Range: DN50 to DN600 (2″ to 24″) – covering most industrial pipeline requirements.

• Customizable Pressure Ratings: Available in PN10, PN16, PN25, Class 150, or as specified.

• Actuator Ready: The top flange can be machined to ISO 5211 standards for direct mounting of electric or pneumatic actuators.
