Electric High-Performance Butterfly Valve
Electrically driven double/triple-offset butterfly valve with reliable sealing and low torque, ideal for remote control in high-temperature, high-pressure severe service.
Inquire NowProduct Overview
High-performance butterfly valves use double-offset or triple-offset geometry to achieve cam-action seating with near-zero friction between the disc and seat. Combined with a multi-turn electric actuator, they deliver precise positioning for modulating and tight shutoff for isolation service in demanding conditions.
These valves handle temperatures from -196C to +800C with pressure ratings up to Class 1500, making them a cost-effective alternative to gate and globe valves in severe service.
Key Features
- Friction-Free Seating: Offset design eliminates seat wear during opening/closing
- Zero Leakage: Metal-to-metal or laminated seal achieves ANSI Class VI tight shutoff
- Fire-Safe Certified: API 607 / ISO 10497 fire-safe design standard
- High Temp Range: Handles cryogenic to high-temperature service with appropriate trim
- Electric Precision: Smart electric actuator with 4-20mA control, Modbus/Profibus options
Technical Highlights
