Overview
The Smith-Cooper 4798 ball valve is a premium-grade brass ball valve engineered for general-purpose fluid control in industrial and commercial systems. This 1/4″ NPT model combines durable brass construction with quarter-turn operation, providing reliable on-off control with minimal leakage. The full-port design minimizes pressure drop and allows straightforward installation in new builds and retrofit applications.
Key Features
- 1/4″ NPT threaded connections for standard pipe compatibility
- Full-port design minimizes flow restriction
