Pneumatic PVC-U ball valve Type 230 DA PN10

  Datasheet.pdf

The Georg Fischer Type 230 DA is an industrially configured, pneumatically actuated PVC-U ball valve engineered for automated on-off fluid control in chemical processing, industrial water treatment, and distribution systems. Designed with a double-acting pneumatic actuator, this unit utilises compressed air to drive both opening and closing cycles, delivering reliable quarter-turn operation without relying on mechanical return springs. Rated for an operating pressure of up to 10 bar (PN10) at 20 degrees Celsius, the valve body is constructed from high-grade unplasticised polyvinyl chloride (PVC-U), providing robust structural rigidity and broad resistance to inorganic acids, bases, and salt solutions.

Actuator sizing is engineered to match valve torque requirements across the dimensional spectrum from d16 up to d110 (DN10 to DN100). The pneumatic actuator assignment scales systematically: PA11 covers DN10 to DN25, PA21 operates DN32 to DN50, PA35 controls DN65, PA40 actuates DN80, and PA45 drives DN100. Across all dimensions, the unit achieves an exceptionally fast cycle speed, executing a complete 90 degrees rotation within 1 to 2 seconds under standard control air pressures. To ensure seamless mechanical integration into piping brackets and plant framing, the valve body features integrated stainless steel threaded mounting inserts, preventing stress concentration in the thermoplastic body during mounting and heavy cycling.

The true union architecture facilitates rapid radial installation and removal from existing pipe networks without displacing adjacent pipe segments or disturbing solvent cement joints. Premium PTFE ball seats ensure low operating friction, consistent sealing torque, and long service longevity in demanding process lines. Available with solvent cement socket union ends across metric diameters from 16 mm to 110 mm, the Type 230 DA ball valve is an ideal automation solution for automated cooling circuits, neutralization plants, and chemical transfer manifolds requiring durable, maintenance-friendly process isolation.
