ASCO Series 158 Gas Valve and Series 159 Motorized Actuator – Emerson
FLORHAM PARK, N.J. — Emerson’s ASCO™ Series 158 Gas Valve and Series 159 Motorized Actuator is designed specifically for burner-boiler applications. The new products give OEMs, distributors, contractors, and end users a new combustion safety shutoff valve option that increases safety and reliability and enhances both flow and control.
The new valve offers a higher close-off pressure of 75 psi (5.2 Bar) ensures a safe shutoff in the event of a fuel train system failure and eliminates the need for additional safety components. The valve offers a flow rate that is twice that of other combustion valves on the market. As a result, it offers a high Btu rating as well as the ability to deal with varying gas inlet pressures without a reduction in burner performance and operation. Installation is also made easier with end connectors that eliminate the need for piping unions and a ventless compatible monoblock design that not only does away with the need for additional vent piping but also limits greenhouse gas and vent emissions.
