The ASCO™ Series 047 Manual Reset Solenoid Valves offer reliable control with a latching solenoid actuation, suitable for various media, including air, inert gas, light oil, steam, and water. Available in brass and stainless steel, these 3/2 universal function valves feature a 1/2" NPTF port with flow rates from 0.1 Cv to 0.5 Cv. Designed for corrosive and hazardous indoor environments, they meet CSA, Type 3, 7, and 9 standards and support voltages from 6 DC to 480 AC, making them ideal for critical refining and chemical production applications.

Key features and benefits of the ASCO™ Series 047 Manual Reset Solenoid Valves

Key Features

These valves incorporate a manual reset mechanism, ensuring that once tripped, they can only be returned to automatic operation through manual intervention. This feature enhances safety by preventing unintended valve activation.

Key Features

The valves are available in three configurations: electrically tripped (activates when energized), no-voltage release (activates when de-energized), and free-handle constructions. This versatility allows for tailored control strategies to meet specific application requirements.

Key Features

Models ranging from 1/2-inch to 1-inch NPT feature poppet construction, providing high flow rates alongside tight shutoff capabilities. This design ensures efficient fluid control and reliable sealing, making them suitable for demanding industrial applications.
