Product: ASCO Series 158 Gas Valve and Series 159 Motorized Actuator

Description: The product offers a close-off pressure of 75 psi and provides an elevated flow rate resulting in a high Btu rating. It has the ability to deal with varying gas inlet pressures without a reduction in burner performance and operation. Installation is simplified with end connectors that eliminate the need for piping unions, plus a ventless compatible monoblock design that does away with the need for additional vent piping but also limits greenhouse gas and vent emissions. The ASCO Series 158 is a gas valve range available in sizes from ¾-inch NPT to 3-inch 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 minus 40°F to 150°F and is offered with an optional watertight National Electrical Manufacturers Association (NEMA)-approved Type 4 enclosure. Both 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.
