Key Technical Advantages & Design Innovations:

1. Innovative Split Body for Effortless Maintenance

• Quick Internal Access: The unique two-piece body, secured by perimeter bolts, can be opened directly on the line. This allows for inspection, seat replacement, or disc service in minutes, without cutting the pipeline or disturbing adjacent flanges.

• Minimized Operational Disruption: Eliminates costly and time-consuming full valve removal, significantly reducing maintenance windows and total cost of ownership.

• Superior Cleanability: Ideal for sanitary or CIP (Clean-in-Place) processes, as the body can be opened for thorough cleaning and validation.

2. Full PTFE Seat for Universal Chemical Compatibility

• 100% Corrosion Resistance: The virgin PTFE seat provides inert, non-contaminating sealing against virtually all aggressive media, including strong acids, alkalis, and solvents across the full pH 0-14 spectrum.

• Bubble-Tight Shutoff: Ensures ANSI Class VI (Zero Leakage) sealing performance, tested to EN 12266-1 Class A standards.

• Wide Temperature Range: The PTFE seat maintains integrity in services from -35°C to 200°C .

3. CF8M Stainless Steel Disc for Durability

• Enhanced Corrosion & Erosion Resistance: The CF8M (AISI 316) stainless steel disc offers excellent protection against pitting and chloride stress corrosion, ensuring long-term structural integrity in harsh environments.

• Precision-Machined Surface: Optimized for perfect, low-friction contact with the PTFE seat, ensuring smooth operation and extended cycle life.

4. Compact and Efficient Wafer Design

• Space and Weight Savings: The wafer-style body installs directly between ANSI or DIN flanges using through-bolts, offering a lighter and more compact solution compared to lug-type or flanged body valves.

• Cost-Effective Installation: Reduces overall installation time and hardware requirements.
