Product Overview
The VALBIA 82DA0010 is a double-acting pneumatic rotary actuator from the VALBIA 82 Series, engineered for precise quarter-turn (90°) operation of industrial process valves. Utilizing a rack-and-pinion drive mechanism, this actuator converts pneumatic pressure into controlled rotary torque, providing reliable open/close actuation for ball valves, butterfly valves, and plug valves across demanding process environments. The 82DA0010 is a direct-mount, compact solution designed for seamless integration with standard ISO 5211 valve interfaces, making it a preferred choice for automated process control loops in chemical, water treatment, and general industrial fluid handling systems.

Engineering Features & Advantages
- Precision Rack-and-Pinion Drive: Dual-opposed rack-and-pinion mechanism delivers smooth, backlash-free quarter-turn rotation with balanced torque output in both directions, ensuring accurate valve positioning and repeatable actuation cycles.
- Compact & Lightweight Design: The extruded aluminum body minimizes installation footprint and weight, reducing structural load on valve assemblies and simplifying mounting in space-constrained manifolds and skids.
- Direct Valve Mounting: Standard ISO 5211 bottom flange and Namur accessory interface allow direct mounting of solenoid valves, positioners, and limit switch boxes without additional adapters, reducing installation time and cost.
- Industrial Reliability: Hard-anodized aluminum housing and precision-machined internal components are built for continuous operation under severe industrial conditions, including high-cycle automation and corrosive plant environments.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original VALBIA OEM standards, ensuring drop-in replacement without modification to existing manifolds or piping.
