Emerson Alco 009689 Solenoid Valve

The Emerson Alco 200RB 3T3 (009689) is a pilot-operated 2-way normally closed solenoid valve designed for precision refrigerant control in commercial HVACR systems. This bi-flow refrigeration solenoid valve features 3/8" ODF sweat connections and is engineered for high-performance liquid, suction, or hot gas service. Built with a rugged extended copper tail design, it allows for easy brazing without disassembly, maintaining the integrity of the internal components. It provides a nominal R22 capacity of 4.8 tons and an R134a capacity of 4.4 tons at standard conditions. The valve utilizes a PTFE valve seat to ensure tight shut-off and minimize internal leakage across high pressure drops. Compatible with HCFC and HFC refrigerants, this valve body requires a standard ASC2 solenoid coil for operation. Its pilot-operated diaphragm construction ensures reliable opening even under low pressure differential conditions encountered in varying load environments.

• Extended Copper Connections: Allows for quick 3/8" sweat installation without damaging internal seals.
• Bi-Directional Flow Capability: Optimizes system design for heat pump applications or complex piping layouts.
• High Pressure Rating: Rated for a maximum working pressure of 680 psig, supporting modern high-pressure refrigerants.
• Normally Closed Logic: Ensures positive system isolation during power loss or thermostat cycles.
• Field Serviceable: The top-entry design allows for internal component cleaning or replacement if necessary.

What coil is required for the Emerson 009689 solenoid valve?
This valve body is designed to work with the Emerson ASC2 series solenoid coils, available in various voltages including 24V, 120V, and 240V AC.

Can this solenoid valve be installed in any orientation?
For optimal performance and to prevent debris accumulation on the diaphragm, it is recommended to install the valve with the coil in an upright vertical position, though it can be mounted horizontally.

Is the 200RB 3T3 compatible with R-410A?
Yes, the 200RB series is rated for high-pressure refrigerants including R-410A, provided the specific system capacities align with the valve's flow coefficients.
