ASCO 8210D18-24VDC Solenoid Valve

The ASCO 8210D18-24VDC Solenoid Valve is a high-performance, 2-way normally open pilot-operated valve designed for robust flow control in industrial HVACR and process systems. Featuring a durable brass body and high-grade EPDM seals, this 1 1/4" NPT valve is engineered to handle air, water, and light oil with exceptional reliability. With a high flow coefficient of 15 Cv and an operating pressure range of 5-125 PSI, it ensures efficient media management even in demanding environments. Driven by a precise 24Vdc coil and protected by a Nema 1 enclosure, this ASCO 210 series component is a staple for applications requiring a general service solenoid with low internal leakage. Its diaphragm construction provides a long service life, making it an ideal choice for commercial laundry, water control, and air compressor systems.

• Optimized Flow: High 15 Cv flow factor allows for maximum throughput in large-scale piping systems.
• Versatile Media Compatibility: Proven performance with air, water, and light oil (up to 300 SSU).
• Reliable Normally Open Logic: Ensures the valve remains open during power loss, critical for specific safety and process requirements.
• Durable Construction: Rugged brass body and EPDM seals provide superior resistance to wear and chemical degradation.

Common Questions

What is the difference between a normally open and normally closed solenoid valve?
A normally open solenoid valve, like the 8210D18, allows fluid to pass when the coil is de-energized and closes when power is applied. This is often used for venting or systems where flow is the default state.

Can this ASCO valve be used in outdoor environments?
This specific model features a Nema 1 enclosure, which is primarily designed for indoor use to protect against dust and light splashing. For outdoor or watertight requirements, a RedHat II Type 4X enclosure may be needed.

What is the minimum pressure required for this pilot-operated valve?
As a pilot-operated valve, it requires a minimum operating pressure differential of 5 PSI to move the diaphragm and function correctly.
