1. Key Features
• Full/Reduced Port Design – Optimized for high flow capacity (full bore) or space-saving installation (standard bore)
• Bubble-Tight Shutoff – PTFE or metal-seated options (ANSI Class VI/IV)
• Fire-Safe Construction – Complies with API 607/ISO 10497 (optional graphite seals)
• Anti-Static & Blowout-Proof Stem – Ensures safety in flammable media applications
• Pneumatic Actuation – Double-acting or spring-return (fail-safe), with 4-20mA position feedback
2. Performance Advantages
• High Pressure & Temperature Rating – PN16-PN100 (ANSI 150-600), -29°C to 450°C
• Low Torque Operation – Reduces actuator load for energy efficiency
• Corrosion & Wear Resistance – 304/316 stainless steel, optional hard coatings (WC/Stellite)
• Quick 90° Operation – Fast response for process automation
