1. Key Features
• V-Port Ball Design – Provides precise flow control with linear or equal percentage characteristics
• Bubble-Tight Shutoff – PTFE or metal-seated options, meeting ANSI/FCI 70-2 Class VI standards
• Anti-Cavitation & Erosion Resistant – Hardened alloy coating (WC/Stellite) for abrasive media
• Pneumatic Actuation – Double-acting or spring-return (fail-safe) with 4-20mA position feedback
• Fire-Safe Design – Complies with API 607/ISO 10497 (optional graphite seals)
2. Performance Advantages
• High Precision Control – Adjustable flow with 0-90° rotation for fine-tuning
• Wide Pressure & Temperature Range – PN16-PN100 (ANSI 150-600), -29°C to 450°C
• Low Torque Operation – Reduced actuator load for energy efficiency
• Corrosion & Wear Resistance – 316 stainless steel trim, optional epoxy coating
