T-Type vs. L-Type — What's the Difference?

• T-Type: Connects all three ports simultaneously — ideal for flow splitting or mixing from a single inlet to two outlets (or vice versa).
• L-Type: Connects two of the three ports at a time, allowing flow to be redirected 90° — perfect for switching between two separate flow paths.

Why Choose 304 Stainless Steel?

304 stainless steel is one of the most widely used alloys in plumbing and industrial applications. Its chromium-nickel composition provides excellent resistance to corrosion, oxidation, and extreme temperatures — making it suitable for both indoor and outdoor installations.

Frequently Asked Questions

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

A: A T-Type 3-way ball valve allows flow through all three ports simultaneously, making it ideal for mixing or splitting flow. An L-Type 3-way ball valve connects only two ports at a time, redirecting flow 90° from one path to another — ideal for switching between two separate circuits or outlets.

Q: What media is this 3-way ball valve compatible with?

A: This 304 stainless steel ball valve is compatible with water, oil, air, and gas. Its corrosion-resistant construction makes it suitable for a wide variety of residential, commercial, agricultural, and light industrial applications.

Q: What is the maximum operating pressure for these ball valves?

A: These BSP female 3-way ball valves are rated for a maximum operating pressure of less than 850 kPa. Please ensure your system's operating pressure does not exceed this rating for safe and reliable performance.

Q: Are these ball valves food-safe?

A: Yes. The valves are made from 304 stainless steel, which is nationally recognised as a food-grade material and is widely used in food processing, beverage, and medical-grade plumbing systems.

Q: Which BSP sizes are available?

A: These 3-way ball valves are available in 1/4", 3/8", 1/2", 3/4", and 1" BSP female thread sizes, corresponding to DN10, DN15, DN20, and DN25 metric pipe designations. Both T-Type and L-Type configurations are available in the most common sizes.
