What Is a 3/4 in Brass Ball Valve? Definition and Characteristics
The 3/4 in brass ball valve is a quarter-turn valve designed with a spherical ball inside its brass body. The ball contains a hole through which fluid passes when aligned with the flow path. Turning the valve 90 degrees closes the hole, stopping flow. The valve’s 3/4 inch measurement refers to the diameter of the internal passage, compatible with 3/4 inch piping.
Key Characteristics
- Material Strength: Brass provides excellent mechanical strength and corrosion resistance.
- Leak Prevention: PTFE or similar high-grade seat materials offer superior sealing to avoid leaks.
- Ease of Operation: The lever handle allows quick, intuitive quarter-turn control.
- Pressure and Temperature Range: Suitable for pressures up to approximately 200 PSI and temperatures commonly up to 200°F.
- Connection Types: Available with threaded, solder, or compression ends to suit various installations.
This combination makes the valve dependable for preventing leaks while providing reliable flow control.
