Product Overview
The KOZO Q641H / Q641Y Pneumatic High-Temperature Ball Valve is designed for remote on/off isolation where elevated temperature makes conventional soft seats unsuitable.
Key Design Features
- Pneumatic quarter-turn actuator.
- Hard or metal-seat configuration.
- Flanged industrial connection.
- Optional limit switch, solenoid and filter regulator.
Typical Applications
- Thermal oil
- High-temperature process fluids
- Steam-adjacent isolation where design permits
- Severe industrial service
Selection Notes
Maximum temperature must be confirmed from the complete body, seat, packing, gasket, trim and actuator configuration rather than from the model name alone.
