Asco P149A111X1X01F0 Motorized Fuel Oil Actuator

Product Description

The ASCO P149A111X1X01F0 is a Series 149 motorized actuator built for fuel oil burner systems where reliable safety shut-off control is required. It is designed to integrate with ASCO Series 148 valves, forming a complete motorized valve assembly capable of handling high-flow and high-pressure fuel oil service. The on-site adjustable connection accepts either 3/4 inch or 1/2 inch NPT/Rp pipe sizes, and optional adapters and plugs allow the unit to be configured for 3/2 or 2/2 function layouts. Licensed service technicians working on commercial and industrial burner systems will find this actuator suited to demanding, continuous-duty environments.

This actuator is intended for use in fuel oil burner control systems where a motorized safety shut-off valve is required by code or system design. Typical installations include commercial boiler rooms, industrial process heating equipment, and heavy fuel oil handling systems that demand proven, mechanically robust valve actuation. The Series 149 design supports both NPT and Rp thread standards, making it applicable to systems plumbed to either North American or ISO pipe threading conventions.

Key Features

• Designed for direct integration with ASCO Series 148 valves as a matched motorized valve system
• On-site adjustable pipe connection accommodates 3/4 inch or 1/2 inch NPT/Rp sizes
• Configurable for 3/2 or 2/2 function via optional adapters and plugs
• Rated for high-flow and high-pressure fuel oil applications
• Functions as a safety shut-off actuator for critical burner control service

Compatibility

Designed for use with ASCO Series 148 valves in fuel oil burner systems requiring motorized safety shut-off actuation.

Installation Notes

Installation should be performed by a licensed technician familiar with fuel oil burner systems and applicable codes such as NFPA 31 for oil-burning equipment. Shut off the fuel supply and de-energize all control circuits before mounting or wiring the actuator. Verify pipe thread type and size at the connection point before tightening to avoid cross-threading NPT and Rp fittings. Confirm the function configuration with adapters and plugs before placing the system back in service.
