Product Description

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. Specifically designed 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.
