Emerson enhances ASCO 327C solenoid valve lineup

Emerson has expanded its ASCO Series 327C solenoid valve line with new intrinsically safe and manual reset versions designed for high-demand industrial applications. According to the company, the additions enhance safety, reliability, and response time for facilities operating in power generation, refining, and chemical processing.

The ASCO Series 327C is a direct-acting, high-flow solenoid valve built for harsh environments, with operating temperatures ranging from –60 to 90°C. The valve uses a balanced poppet design to support high-flow efficiency and incorporates a two-layer dynamic seal intended to reduce friction and prevent stiction throughout its service life.

The new intrinsically safe construction eliminates the need for an electronic booster, which Emerson says supports more consistent partial stroke testing and enables faster actuation. The manual reset version offers additional operational control for users managing safety-critical processes.

Anne Sophie Kedad, Director of Marketing for Process and Sustainability at Emerson, said the enhancements address industry demand for durable valves that reduce maintenance and downtime in challenging environments. She noted that the intrinsically safe model simplifies the overall design by removing external electronic components.

Emerson reports that the Series 327C is globally approved, giving industrial users a standardized option that can reduce specification complexity. Additional features, including an electrical test connection, are intended to streamline commissioning and help prevent moisture ingress during storage.
