1. Key Features
• High-Platform Cast Bracket: Enhanced structural support for heavy-duty actuators, minimizing stem deflection
• Pneumatic Actuation: Double-acting or spring-return (fail-safe) options, compatible with 4-20mA control signals
• Bubble-Tight Shutoff: PTFE or metal-seated options, meeting ANSI/FCI 70-2 Class VI leakage standards
• Anti-Blowout Stem: Prevents stem ejection under high-pressure conditions
• Fire-Safe Design: Complies with API 607/ISO 10497 (optional fireproof graphite seals)
2. Performance Advantages
• High Pressure & Temperature Resistance: Rated for PN16-PN100 (ANSI 150-600) and temperatures from -29°C to 450°C
• Corrosion Protection: 316 stainless steel trim & optional epoxy coating for harsh environments
• Low Friction & Long Life: Hardened ball (WC coating available) and self-lubricating seats reduce wear
• Quick 90° Operation: Ensures fast response for process control
