The ABS Metric 3-Way T-Port Durapipe Pneumatically Actuated Ball Valve is a robust automated solution for diverting and mixing flow within metric ABS pipework systems. This assembly combines the Durapipe TKD DualBlock® 3-way ball valve with a Prisma pneumatic actuator, providing dependable performance in industrial and process environments.

The T-port ball design allows fluid to be diverted to two outlets simultaneously or mixed from two inlets into a single outlet, depending on valve position. With four selectable operating positions, the valve offers excellent flexibility for complex flow-routing applications where controlled distribution is required.

Constructed from ABS with EPDM seals, the valve delivers strong chemical resistance and long service life when handling water and many industrial fluids. Its fully unionised design allows the valve body to be removed from the pipeline without cutting the pipe, making inspection and seal replacement straightforward.

The Prisma pneumatic actuator provides fast quarter-turn operation and is ATEX and SIL3 approved, making it suitable for hazardous or safety-critical installations. The IP67-rated polyamide housing, stainless steel drive interface and NAMUR connection allow easy integration into automated control systems.
