Asco P159A111X1X11F0 Series 159 Motorized Actuator 120V Fast-Opening On/Off

The Asco P159A111X1X11F0 is a heavy-duty Series 159 motorized actuator designed for reliable gas shut-off control in industrial heating applications. This self-contained electrohydraulic linear actuator features dual internal control valves for precise and repeatable positioning throughout its operational cycle.

Key Features:

• 120V AC operation (120/60, 110/50 Hz) with On/Off control configuration
• Fast-opening actuation for rapid response in emergency shut-off situations
• Watertight enclosure (IP65/Type 4) suitable for harsh environments
• Damper shaft with arm mounting option for auxiliary damper control
• Aluminum body construction for durability and corrosion resistance
• Built-in position indicators on both sides display open/closed valve status
• Broad ambient temperature range: -40°F to 150°F (-40°C to 66°C)
• 1/2 inch NPT electric connection fitting
• Maximum closing time of 1 second for quick safety shutdowns

When mounted to an ASCO Series 158 or V710 gas valve body, this actuator creates a globally certified safety shut-off solution ideal for boilers, furnaces, ovens, dryers, incinerators, thermal oxidizers, and other industrial heating systems. The actuator can be mounted in any position and provides consistent performance across extreme temperature environments. This model does not include auxiliary switches or proof-of-closure switches.
