ASCO 8210G207-24VDC Solenoid Valve

The ASCO 8210G207-24VDC is a pilot-operated 2-way normally closed solenoid valve engineered for high-cycle industrial fluid control. Featuring a rugged brass body and 1/2" NPT connection, this general service valve is optimized for air, inert gas, water, and light oil. The 24V DC solenoid coil is housed in a NEMA 4X enclosure, providing superior corrosion resistance and watertight protection for demanding mechanical rooms or outdoor installations. With a flow coefficient (Cv) of 3.0 and an operating pressure differential (OPD) ranging from 5 to 175 PSI, it ensures consistent shut-off performance. The NBR (Nitrile) seals offer reliable compatibility with standard HVACR fluids. Designed for internal piloting, this valve requires the minimum pressure differential to function, making it an industry standard for automated process systems and commercial plumbing applications where reliability is non-negotiable.

Key Benefits for Contractors

• NEMA 4X Protection: The watertight, corrosion-resistant enclosure allows for installation in harsh environments without internal coil degradation.
• High Flow Efficiency: A 3.0 Cv rating provides high volume throughput with minimal pressure drop across the 1/2 inch orifice.
• Direct 24V DC Integration: Optimized for modern PLC and digital control circuits, minimizing power consumption with a 10.5W rating.
• Resilient Seat Material: NBR elastomers provide excellent sealing properties for water and pneumatic service up to 180°F.

Common Questions

What is the minimum operating pressure for this valve?
The ASCO 8210G207 is a pilot-operated valve and requires a minimum pressure differential of 5 PSI to open and stay open.

Can this valve be mounted in any orientation?
While often mounted with the solenoid vertical and upright, it is recommended to check specific piping clearances; however, upright mounting minimizes the risk of sediment accumulation in the core tube.

Is this valve suitable for steam service?
No, this model uses NBR seals and is rated for air, water, and light oil. Steam applications typically require EPDM or PTFE seals and a specialized coil insulation class.
