The ABS Metric 3-Way L-Port Durapipe Pneumatically Actuated Ball Valve is a high-performance automated flow-diverting solution for metric ABS pipework systems. This assembly pairs the Durapipe TKD DualBlock® 3-way ball valve with a Prisma pneumatic actuator, delivering precise, repeatable flow control in demanding industrial environments.

The L-port ball configuration allows flow to be directed from a single inlet to one of two outlets, making the valve ideal for diverting and line-selection applications. With four selectable operating positions, the valve also allows full isolation when required, offering excellent flexibility within complex pipework layouts.

Manufactured from ABS with EPDM seals, the valve provides strong chemical resistance, high impact strength and long service life. The fully unionised DualBlock® design allows the valve body to be removed from the system without cutting the pipe, simplifying inspection, maintenance and seal replacement.

The Prisma pneumatic actuator offers fast quarter-turn operation through a 0–90° rotation and is ATEX and SIL3 approved, making it suitable for hazardous or safety-critical installations. Its robust polyamide body, stainless steel drive interface and NAMUR connection ensure reliable automation and straightforward integration with solenoid valves.

• L-port configuration: Directs flow between two outlets or fully isolates the line
• Four operating positions: Flexible flow selection and control
• Durapipe TKD DualBlock® valve: Proven industrial performance
• Fully unionised construction: Easy valve removal without disturbing pipework
• EPDM seals: Suitable for water and many industrial fluids
• High pressure capability: Up to 16 bar at 20°C
• Prisma pneumatic actuator: ATEX and SIL3 approved for demanding environments
• IP67 protection: Suitable for harsh industrial conditions
