YE200MX Electric Pilot-operated Cage-style Control Valve

S-shaped flow path with integrated flow guide vane ensures low pressure drop, high flow capacity, wide adjustable range (50:1), and precise flow characteristics (±1% accuracy).

Enhanced with a pilot plug for precise low-opening regulation, improving overall control capability beyond standard cage-style valves.

Class V shut-off capability (ISO 5208) with robust sealing, suitable as vent shut-off valve.

High capacity, excellent dynamic stability (per IEC 60534-8-3), and compatibility with harsh operating conditions (-196°C to 650°C).

Compact electric actuator design with high thrust output (up to 80kN), supporting HART/PROFIBUS communication.
