## Long description

The CALEFFI BallStop Ball Valve 1/2 Inch with Built-in Check Valve is an engineered plumbing component designed to regulate fluid flow while preventing reverse flow in residential and commercial applications. This reliable shut-off and check valve combination integrates two essential functions into a single compact unit, streamlining system layouts and reducing the number of individual fittings required.
Advantages

The robust construction ensures dependable operation under standard operating conditions in both heating and plumbing setups, while the integrated check valve reliably stops backflow to protect upstream equipment.
Suitable for
Residential plumbing systems

Streamlining compact piping layouts
When it may not be suitable

How to use
