ASCO P159A120X1X11F0 Actuator

The ASCO P159A120X1X11F0 Motorized Actuator is a high-performance 120V electrohydraulic linear actuator designed for precise combustion system control. Specifically engineered as the direct replacement for AH2E202A4, this unit provides reliable On/Off or High/Low/Off positioning for industrial burners and boiler systems. With a 26-second actuation time and an integrated damper arm, it ensures smooth, repeatable valve automation. Its self-contained design features a durable aluminum body, making it ideal for HVACR commercial applications where reliability is paramount. Compatible with ASCO Series 158 and V710 valve bodies, the actuator includes dual internal control valves and visual position indicators on both sides. The adjustable low-fire position (15% to 100% of stroke) allows for fine-tuning fuel-to-air ratios, maximizing thermal efficiency and system safety in demanding environments.

• Seamless Integration: Serves as the primary replacement for AH2E202A4, ensuring minimal downtime during system maintenance.
• Enhanced Control: Features a built-in damper arm for synchronized control of air dampers and fuel valves.
• Precision Engineering: The electrohydraulic actuator design provides consistent, drift-free positioning for optimal combustion.
• Versatile Setup: Easy field adjustments for low-fire settings from 15% to 100% of the stroke length.
• Rugged Durability: Constructed with a corrosion-resistant aluminum housing for long-term industrial use.

Is the ASCO P159A120X1X11F0 compatible with my existing valve?
This actuator is specifically designed for use with ASCO Series 158 and Series V710 gas valves. Always verify the stroke and mounting requirements of your valve body before installation.

What is the advantage of a 26-second opening time?
A 26-second opening time provides a controlled, gradual ramp-up in gas flow, which is often preferred in large burner applications to ensure smooth ignition and reduce thermal stress on the system.

Can I adjust the low-fire position?
Yes, the low-fire position is factory-set at the midpoint but can be easily adjusted by the technician to anywhere between 15% and 100% of the total stroke to meet specific firing requirements.
