Automation Components Inc (ACI) 133044 Valve

The Automation Components Inc (ACI) 133044 Valve is a high-precision voltage to pneumatic transducer engineered for reliable HVAC control systems and industrial automation. Functioning as a direct cross-reference for the PXP7.3G, this unit facilitates accurate analog to pneumatic conversion, accepting a 0-5 VDC input to modulate a linear 0-15 psi output. This transducer is critical for technicians managing pneumatic actuators, dampers, and valve sequences that require stable pressure regulation from a building automation system (BAS) controller. Its compact design allows for efficient rail or surface mounting in control panels where space is a premium. By utilizing solid-state technology, the ACI 133044 ensures low hysteresis and high repeatability, making it an essential component for maintaining balanced pneumatic control systems and optimizing process control performance in commercial HVAC environments.

Key Benefits for Contractors

• PXP7.3G Compatibility: Designed as a direct drop-in replacement, simplifying field service and inventory management for legacy systems.
• Precision Modulation: Delivers a consistent 0-15# output for smooth operation of pneumatic control valves and actuators.
• Industrial Durability: Robust construction ensures reliable performance in rigorous mechanical room environments and industrial process loops.
• Simplified Integration: The 0-5 VDC input signal allows for seamless communication with modern electronic controllers.

Common Questions

Is the ACI 133044 compatible with a 10 VDC signal?
This specific model is calibrated for 0-5 VDC. Using a higher voltage signal outside the specified input range will result in inaccurate pressure output. Always verify your controller's output range before installation.

What is the primary application for this transducer?
The ACI 133044 is primarily utilized to convert electronic signals from a BAS into pneumatic pressure for HVAC systems, modulating dampers, and controlling pilot-positioners.

Does this unit come as a complete kit?
The 133044 includes the electronic-to-pneumatic conversion board. Ensure your supply air is clean, dry, and regulated according to the technical specifications to prevent orifice clogging.
