The ARI-ZETRIX 018 is a high-performance, triple-offset butterfly process valve with metallic sealing, designed for demanding industrial applications like oil & gas, power, and chemical plants, offering a long, maintenance-free life with low torque, bubble-tight shutoff, and broad media/temperature compatibility (e.g., -60°C to +450°C) through its unique design and stellited seats, ensuring reliable isolation in tough conditions.
Key Features & Design
- Triple Offset: The disc, seat, and stem are offset, creating a frictionless, 90° rotary movement for wear-free operation and tight sealing.
- Metallic Sealing: A self-aligning, free-floating sealing ring and stellited seat (Stellite® 21) provide a permanent, leak-proof seal.
- Heavy-Duty Construction: Available in cast steel or stainless steel bodies with hardened stainless steel bearings, built for harsh industrial environments.
- Versatile: Handles liquids, gases, steam, and extreme temperatures (-60°C to +450°C).
- High Integrity: Vacuum-tight, firesafe (API 607/ISO 10497), and compliant with standards like TA-Luft/ISO 15848 (optional).
- Application: Ideal for refineries, power plants, petrochemicals, district heating, and other critical systems needing reliable flow control.
Benefits
- Low Torque: Requires minimal force to open and close, reducing actuator size and cost.
- Extended Life: No friction during movement means less wear and longer service intervals.
- Superior Sealing: Achieves bubble-tight shutoff for critical isolation needs.
