Schneider Electric (Barber Colman) AL-190 Valve

The Schneider Electric AL-190 is a specialized 24Vac solenoid air valve engineered for pilot-duty applications within pneumatic control systems. This unit functions as a high-reliability interface, converting electrical signals into precise pneumatic actions. Rated at .59 scfm, the AL-190 features a durable plastic body construction and comes equipped with a dedicated mounting bracket and fittings compatible with 1/4" O.D. plastic tubing. For technicians managing legacy systems, the AL-190 serves as the direct replacement for AL-99 and AL-100 models, ensuring seamless integration without the need for extensive field modifications. Its low power consumption and high cycle life make it a standard choice for pneumatic solenoid valve replacements in commercial HVAC environments. When installing this Barber Colman valve, ensure the supply air is clean and dry to maintain the integrity of the internal components and prevent premature failure in demanding environments.

• Legacy Compatibility: Engineered as a drop-in replacement for obsolete AL-99 and AL-100 series valves, reducing downtime during retrofits.
• Installation Ready: Includes a factory-supplied mounting bracket and specialized fittings for standard 1/4 inch tubing, simplifying field labor.
• Electrical Efficiency: Optimized 24Vac coil design minimizes current draw on the control transformer while maintaining consistent actuation.
• Compact Footprint: The consolidated plastic housing allows for mounting in tight control cabinets where space is at a premium.

Is the AL-190 compatible with 1/8" NPT fittings?
The unit is primarily designed for use with 1/4" O.D. plastic tubing via the included compression fittings; however, standard adapters can be used if your specific pneumatic logic layout requires different connection types.

Can this valve be used for direct actuator control?
With a flow rate of .59 scfm, this valve is best utilized as a pilot signal device or for controlling small-volume actuators and pneumatic relays.

Does the AL-190 support continuous duty cycles?
Yes, the 24Vac solenoid is designed for continuous energization, making it suitable for binary control sequences in sequence-of-operations logic.
