Emerson Alco 030620 Valve

This Emerson Alco 030620 Valve is a 2-way normally closed solenoid valve designed for demanding industrial fluid control. Operating as a pilot operated solenoid valve, it utilizes a 1/2" NPT connection and features a 3.6 Cv flow coefficient to ensure high-capacity regulation of water and air systems. This robust solenoid valve body is the direct engineering replacement for the legacy 210CA-1/2-B-5/8 model, specifically optimized for water application environments where reliability is non-negotiable.

Constructed with a durable brass body and stainless steel internal components, the Emerson 030620 handles a 0-150 PSI operating pressure range. The normally closed (NC) configuration ensures the valve remains securely shut when de-energized, preventing unintended flow. This 210CA series component is a staple for contractors maintaining HVACR systems, chillers, and industrial boilers that require a precise 5/8" orifice equivalent performance and long-term operational efficiency.

• Direct Replacement: Seamlessly replaces 210CA-1/2-B-5/8 for field-ready installations in existing water lines.
• High Flow Capacity: A 3.6 Cv rating minimizes pressure drop across the 1/2 inch NPT ports.
• Industrial Durability: Rated for up to 150 PSI, making it suitable for high-pressure air and water applications.
• Reliable Sealing: Features high-grade resilient materials to minimize internal leakage and ensure fail-safe performance.
• Technician-Friendly Design: Pilot-operated mechanism allows for efficient handling of 2-way fluid circuits with standard coil configurations.

Is the 030620 compatible with steam applications?
While the 210CA series has variants for multiple media, the 030620 is specifically designated as the direct replacement for water and air applications. Always verify the elastomer and seal compatibility if using for anything other than neutral fluids.

What is the difference between this and the original 210CA-1/2-B-5/8?
The 030620 is the current Emerson Alco part number for this specific industrial solenoid valve. It maintains identical 1/2" NPT threading and performance specs to ensure full backward compatibility for technicians.

Does this valve require a minimum pressure to operate?
As a pilot operated valve, a minimum differential pressure is typically required for the diaphragm to lift. Check your system's static pressure to ensure it meets the 210CA series requirements before installation.
