Frequently Asked Questions

Q: What is the difference between a T-Port and L-Port 3-way ball valve?

A: A T-Port ball valve uses a T-shaped internal bore and allows flow between any two or all three ports simultaneously via a 180° handle rotation. An L-Port ball valve uses an L-shaped bore and switches flow between two of three ports at a time with a 90° handle rotation. The T-Port is better for mixing or diverting flows, while the L-Port is ideal for simple two-path diversion.

Q: What sizes are available and what thread standard do they use?

A: This brass 3-way ball valve is available in five BSP (British Standard Pipe) female thread sizes: 1/4", 3/8", 1/2", 3/4", and 1". BSP is a widely used international standard compatible with most plumbing and hydraulic fittings.

Q: Is this valve suitable for gas and oil lines, not just water?

A: Yes. This valve is rated for use with water, air, oil, and gas at normal operating temperatures and medium pressure (PN16). Always ensure your specific installation meets local codes and the pressure/temperature requirements of your application.

Q: Does the valve require any tools or electricity to operate?

A: No electricity or actuator is required. This is a fully manual ball valve operated by a simple iron lever handle. Basic plumbing tools are needed for installation, but day-to-day operation is entirely hands-on.
