Asco P149A121X1X01F0 On/Off Motorized Actuator 120V/60Hz 1/2" Series 149

The Asco P149A121X1X01F0 is a Series 149 ON/OFF motorized actuator designed for use with Asco Series 148 safety shutoff valves in fuel oil burner and combustion system applications. Operating at 120V/60Hz, this actuator provides reliable, repeatable open/close valve positioning for critical fuel control and recirculation systems.

Part of the Asco HOV 148/149 system, this actuator pairs with compact 2-way and 3-way Series 148 valve bodies fitted with a 1/2" NPT/Rp port connection. The system is engineered for rapid fail-safe closure — returning to the closed position in less than one second when de-energized — making it a key safety component in industrial and commercial fuel oil burner installations.

Key Features:

• ON/OFF control for straightforward open/close valve operation
• 120V/60Hz power supply compatible with standard North American electrical systems
• 1/2" NPT/Rp port connection size
• Durable aluminum actuator body for long service life
• Fail-safe spring-return closes valve when actuator is de-energized or removed
• Visual open/closed position indication
• Versatile multi-position mounting capability
• Wide ambient temperature range: -40°F to +150°F (-40°C to +66°C)
• Compatible with fuel oils including up to 100% Biodiesel (B100)
• UL Listed, FM Approved, and CSA Certified for combustion compliance

Important: This actuator must be installed by a qualified and licensed contractor using properly calibrated combustion test equipment. It is designed exclusively for use with Asco Series 148 valve bodies — use of non-Asco actuators may create a safety hazard.
