Emerson Alco 030624 Solenoid Valve

The Emerson Alco 030624 is a professional-grade 2-way normally closed solenoid valve specifically engineered for high-demand industrial fluid control. This pilot-operated solenoid valve features a 3/4" NPT connection and a 5.5 Cv flow coefficient, making it an ideal choice for contractors managing hot water and low-pressure steam systems. Designed for reliability under thermal stress, the Emerson 210CA3/4B348P body handles hot water up to 210°F at 0-100 PSI and saturated steam at 0-15 PSI. Its pilot piston design ensures consistent actuation and tight shut-off, which is critical for maintaining system pressure and preventing energy loss in commercial boilers or process heating loops. This industrial solenoid valve body is built for longevity in harsh environments, allowing technicians to swap or service coils without breaking the line. Compatible with standard Emerson Alco coils, the 030624 offers the durability needed for 24/7 HVACR and industrial operations.

• High Thermal Capacity: Optimized for hot water systems and steam applications with a maximum temperature rating of 210°F.
• Precision Flow Control: A 5.5 Cv rating provides efficient throughput for 3/4 inch pipe sizes while maintaining a normally closed safety fail-state.
• Pressure Versatility: Operates effectively from 0 PSI up to 100 PSI (water) or 15 PSI (steam), accommodating varied system pressures.
• Rugged Construction: Built as a pilot-operated valve to provide reliable opening and closing cycles even in high-viscosity or high-temperature media.

• What causes a solenoid valve to hum or buzz? This is often due to low voltage to the coil or debris trapped in the pilot orifice. Ensure the electrical supply matches the coil rating and install a strainer upstream to protect the valve body.
• Can this valve be mounted in any orientation? For the Emerson 210 series, mounting the valve upright with the coil on top is recommended to prevent sediment from accumulating in the enclosing tube, though it is functional in other positions.
• Why is the valve failing to close? Check for a ruptured diaphragm or a manual override that may be engaged. In steam applications, excessive scale buildup can also prevent the pilot piston from seating correctly.
