The ASCO™ Series 381 Solenoid Valves are designed for high-flow, low-temperature applications in harsh and corrosive environments. With a wide operating temperature range from -60°C to 80°C, they can function in extreme conditions. Available in stainless steel and with multiple voltage options, these valves handle air, inert gas, and natural gas. Certified to endure 100,000 cycles, they offer reliable 3/2 normally closed operation and comply with major standards, including ATEX and CSA.

Key features and benefits of ASCO™ Series 381 Solenoid Valves

Key Features

The ASCO™ Series 381 Solenoid Valves are engineered to operate within a broad temperature range, from -60°C to 80°C, making them suitable for both low and high-temperature applications. This ensures reliable performance in environments with extreme ambient or media temperatures, such as arctic conditions or high-heat industrial processes.

Key Features

With flow rates ranging from 2.2 Cv to 6.2 Cv, the Series 381 offers significant flow capacity for air, inert gas, or natural gas. This high-flow capability makes it a versatile choice for systems requiring efficient fluid control, whether in smaller pipelines or larger industrial operations.

Key Features

Built to endure up to 100,000 cycles, including 10,000 cycles at -60°C and 90,000 at 80°C, the Series 381 is tested for long-term reliability. It also meets rigorous certifications such as ATEX, CSA, and IEC, ensuring it is compliant for use in hazardous, corrosive, and outdoor environments while maintaining safety standards.
