ASCO™ Series 158 and 159
Motorized Gas Safety Shut-off Valve and Actuator
Series 158 Valves
The ASCO Series 158 Single and Monoblock valve bodies are a 2-way normally closed gas safety shut-off valve designed for use with the ASCO Series 159 Motorized Actuator. When coupled with the Series 159 actuator, this system meets global approvals with certifications from UL, FM, CSA, and EN161. Designed explicitly for burner applications, these new products give OEMs, distributors, contractors, and end-users a new combustion safety shut-off valve option that increases safety and reliability and enhances heat output.
Series 158 Features:
Optimized high flow design (15.4 to 145.8 CV, 13.3 to 126.1 Kv) and broad operating pressure differential (0 to 20 psi - 0 to 1.4 bar) covers a wide range of applications.
Monoblock construction allows for easy installation and reduces footprint
Broad ambient temperature range suitable for hot (150° F/66° C) or frigid (-40° F/-40° C) environments
3/4'' to 3'' NPT / 20mm- 80mm ISO
Pipe adapters are available to simplify installation and service
Flexible multi-poise field mounting allows installation in any orientation, UL Listed, FM Approved, CSA Certified, and EN161 Class A certified and in compliance with RoHS directives
Series 159 Actuators
The ASCO Series 159 Motorized Actuator is offered in On/Off and High/Low/Off construction. The motorized actuator is a self-contained, electrohydraulic linear actuator featuring dual internal control valves for repeatable positioning. When the actuator is mounted to a Series 158 valve, position indicators on both sides of the actuator show the open or closed position of the valve. The Series 159 Motorized Actuator and Series 158 gas valve combination provide a globally approved safety shut-off solution for a wide range of applications, including boilers, furnaces, ovens, dryers, incinerators, thermal oxidizers, and other heating systems.
