Emerson Alco 064682 Solenoid Valve

The Emerson Alco 064682 is a professional-grade 2-way normally closed solenoid valve engineered for precision fluid control in high-demand industrial environments. Operating under Model 204CD1/4B5/32P, this direct-acting unidirectional valve is specifically designed for steam applications featuring a robust brass valve body that stands up to 0-100 PSI steam pressure. With a 1/4" NPT connection and a 0.48 Cv flow coefficient, it ensures reliable shut-off performance for HVACR and industrial process control systems. This industrial solenoid valve utilizes a 5/32" port orifice to manage flow rates effectively, while the stainless steel enclosing tubes provide enhanced component life in high-temperature settings reaching up to 400°F. For contractors and technicians, the Emerson 204CD series represents a standard in durability, offering a Normally Closed (NC) configuration that remains securely shut until energized, preventing accidental flow during power loss or system standby.

• Steam-Rated Performance: Engineered with high-temperature internal components to handle 0-100 PSI steam and environments up to 400°F without degradation.
• Direct-Acting Reliability: The direct-acting design allows for operation even at zero pressure differential, ensuring the valve opens and closes reliably regardless of line pressure.
• Durable Brass Construction: The industrial brass valve body provides maximum corrosion resistance and structural integrity for long-term service in boiler and mechanical rooms.
• Standardized Compatibility: Features the widely utilized 1/4" NPT threaded connection, making it a direct-fit replacement for most industrial steam control manifolds.

Is this valve suitable for water or air as well?
Yes, while highly optimized for steam, the Emerson 204CD1/4B5/32P is also compatible with air and water. However, focus should remain on the 100 PSI limit for steam compared to higher ratings for other media.

What is the flow direction for this solenoid?
This is a unidirectional valve. To ensure proper operation and prevent backflow issues, follow the flow arrow indicated on the brass valve body during installation.

Can I use a different coil with this valve body?
While the 064682 PCN identifies the valve assembly, the 204CD series supports various voltages. Ensure your replacement coil matches the mechanical and electrical specifications of the Emerson solenoid frame to prevent overheating.
