February 3, 2020 – Emerson introduced the ASCO Series 158 Gas Valve and Series 159 Motorized Actuator. Designed specifically for burner-boiler applications, the products give OEMs, distributors, contractors and end-users a combustion safety shutoff valve option.
The valve offers a 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. Installation is also made with end connectors that eliminate the need for piping unions and a ventless compatible monoblock design that does away with the need for additional vent piping and limits greenhouse gas and vent emissions.
The ASCO Series 158 is a gas valve range available in sizes from ¾” NPT to 3” NPT (DN 10 to DN 80) in both single and monoblock constructions. The ASCO Series 159 Motorized Actuator has a rugged construction, can mount in any position and offers a visual indication of opening. This safety shutoff valve is rated for an ambient temperature range of -40°F to 150°F (-40°C to 66°C) and is offered with an optional watertight National Electrical Manufacturers Association (NEMA)-approved Type 4 enclosure.
The Series 158 and Series 159 meet up-to-date National Fire Protection Association (NFPA), UL, Canadian Standards Association (CSA) and FM Global standards and have earned Restriction of Hazardous Substances (RoHs) and European Standards (EN) approvals.
