Overview
The Bettis DS0200.U2A04K.22K is a precision-engineered pneumatic rack and pinion double-acting actuator from the D-Series lineup. Rated for 120 PSIG maximum operating pressure, this actuator delivers reliable quarter-turn control for ball, butterfly, and plug valves in industrial automation, process control, and HVAC applications. The robust design ensures consistent performance in demanding environments with minimal maintenance requirements.
Key Features
- Double-acting pneumatic operation for smooth, controlled valve positioning
- 120 PSIG maximum operating pressure rating
- Rack and pinion mechanism for precise torque delivery
- Compact design suitable for space-constrained installations
- Visual indication knob for position monitoring
- Designed for dry or lubricated air, inert gases
Technical Specifications
This pneumatic actuator features a standard ISO 5211 mounting interface with UNC bolt holes on the valve mounting side and NAMUR-compatible mounting patterns. The unit operates across a temperature range of -4°F to 176°F (-20°C to 80°C) and accommodates both single and multi-position valve operations. Dual travel stops are included as standard for precise end-of-stroke positioning. The unit is manufactured with Bettis orange color coding and includes a visual position indication knob for easy operator verification of valve status.
