Product Overview
The KOZO High-Temperature Metal-Seated Ball Valve is designed for severe industrial service where conventional soft seats cannot withstand the required temperature or solids loading. Metal seating and hard-facing can be selected to improve wear resistance and maintain shut-off performance.
Key Design Features
- Metal-to-metal seat configuration.
- Hard-faced sealing surfaces available.
- Quarter-turn isolation.
- Extended bonnet/stem options where temperature isolation is required.
- Manual or automated operation.

Typical Applications
- High-temperature process fluids
- Thermal oil
- Steam-related isolation where design permits
- Dirty or solids-containing severe service
Selection Notes
High-temperature capability must be based on the complete design, including body, ball, seat hard-facing, stem packing, gasket, bolting and actuator/gear environment. One metal-seat configuration should not be generalized to all sizes/classes.
How to Specify This Valve
Please provide size, class, medium, temperature, solids content, leakage requirement, body/trim/hard-facing materials, connection and actuation.
