Overview
The Smith-Cooper 4798 ball valve is a 3/8″ NPT full-port brass valve engineered for industrial, commercial, and plumbing applications requiring dependable on-off flow control. With a 600 psi WOG (water, oil, gas) working pressure and 150 psi WSP (water service pressure) rating, this valve delivers the pressure handling capability needed for demanding systems. The forged brass body and chrome-plated ball provide corrosion resistance and longevity in diverse fluid media.
Key Features
- Full Port Design: Minimizes pressure drop and allows maximum flow capacity
- PTFE Seats and Seals: Chemical-resistant, reliable sealing across pressure cycles
- Forged Brass Body: Inherent corrosion resistance, suitable for water, oil, and gas service
- Chrome-Plated Ball: Enhanced durability and smooth operation
- Blow-Out Proof Stem: Prevents stem ejection under pressure, improves safety
- Quarter-Turn Operation: Quick on-off control with minimal effort
