ASCO SC8240S407 Valve

The ASCO SC8240S407 is a high-performance 2-way normally closed solenoid valve specifically engineered for demanding steam and hot water applications. Operating as a pilot-operated unit, this 1/2 inch NPT valve features a robust brass body and a PTFE seat, providing exceptional durability and resistance to high-temperature fluids up to 340°F. Designed for reliable fluid control, it maintains a 0 to 120 PSI differential pressure range, making it ideal for industrial laundry, commercial kitchens, and HVAC boiler systems. Powered by a 120V AC coil, the ASCO 8240 series ensures precise flow management with a 2.93 Cv flow coefficient. This genuine ASCO general service valve utilizes a stainless steel core and plugnut to prevent corrosion in saturated steam environments. Whether you are replacing a worn unit or installing a new heating system, this 120V solenoid valve provides the heavy-duty performance required for consistent pressure regulation and thermal efficiency in extreme mechanical environments. Key Benefits

• High-Temperature Resilience: Equipped with PTFE seals to handle steam and water up to 340°F without degradation.
• Optimized Flow Capacity: Features a 3/8" orifice and 2.93 Cv rating for efficient high-flow fluid control.
• Fail-Safe Operation: The normally closed configuration ensures the valve stays shut during power loss for enhanced safety.
• Industrial-Grade Construction: Corrosion-resistant stainless steel internal components and brass body for long-term reliability.
