Durapipe 3-Way Ball Valves

Durapipe ABS 3-way ball valves are designed for applications where flow diversion or mixing is required within an ABS pipework system. Manufactured by Durapipe to exacting standards, these valves combine robust construction with intelligent design features, making them a reliable choice for industrial, water treatment and process control installations.

Available in sizes from ½" to 2", the range includes both L-port and T-port configurations, allowing you to select the correct valve type for your specific flow requirements. All valves feature plain ends for solvent weld installation, ensuring secure, leak-free joints without the need for hot works.

• Suitable for industrial, water treatment and process applications

Durapipe ABS 3-way ball valves provide a dependable, flexible solution for complex flow control requirements, combining ease of installation with long-term performance and serviceability.

While both valve types are used to control and redirect flow, their internal bore designs offer distinct functionality:

T-Port Ball Valves

The ball is drilled with a T-shaped bore, allowing:

• One inlet to feed two outlets simultaneously
• Two inlets to be mixed into a single outlet

When fully open, flow can pass through multiple directions at once, making T-port valves ideal for mixing or distribution applications.

L-Port Ball Valves

The ball features an L-shaped bore, meaning:

• Flow is diverted between outlets, but only one flow path is open at a time
• The valve can be fully closed, stopping all flow

L-port valves are commonly used for flow diversion where isolation is required.

Durapipe ABS 3-way ball valves incorporate the patented DualBlock® locking system, which prevents union nuts from loosening due to vibration, pressure changes or thermal expansion. This significantly improves long-term system integrity, particularly in demanding installations.

The fully unionised design allows the valve body to be removed easily from the pipeline, enabling seal and seat replacement without disturbing surrounding pipework. The integrated Seat Stop ball seat carrier provides fine micro-adjustment and compensation for axial pipe loads, often without the need to drain the system - saving both time and cost during maintenance.
