Emerson Alco 064267 Solenoid Valve
The Emerson Alco 064267 (Model 200RB7T5M) is a heavy-duty, pilot-operated refrigeration solenoid valve designed for high-capacity flow control in commercial HVACR systems. Built as a 2-way normally closed valve, this component is frequently utilized in liquid, discharge, or suction gas services. It features 5/8" ODF sweat connections with extended copper ends, facilitating a clean brazing process without requiring valve teardown. This specific model includes a manual stem, an essential feature for technicians needing to manually override the valve during system evacuation, charging, or troubleshooting. With a robust R22 capacity of 17 tons and an R134a capacity of 12.7 tons, the 200RB series is a staple for contractors maintaining large-scale refrigeration racks and air conditioning units. The valve utilizes a PTFE O-ring for superior external sealing and is compatible with a single coil family that fits all 200RB sizes, simplifying truck stock and field replacements.
Key Benefits- Manual Override Capability: The integrated manual stem allows for physical valve actuation during power loss or system commissioning.
- High-Flow Performance: Optimized for high-tonnage applications, supporting up to 17 tons of cooling capacity with R22.
- Durability in Extreme Conditions: Rated for a maximum fluid temperature of 250°F and a maximum working pressure (MWP) of 500 psig.
- Field Serviceable: Designed for longevity with available valve repair kits and a pilot-operated design that ensures reliable opening even at low pressure differentials.
- Versatile Refrigerant Compatibility: Suitable for use with R22, R134a, R404A, R507, and other common HCFC/HFC blends.
Does this valve include the solenoid coil?
No, this is a Valve Less Coil (VLC) body. You must pair it with a compatible Emerson AMG or ASC solenoid coil based on your specific voltage requirements (e.g., 24V, 120V, or 240V).
Can this valve be used for bi-directional flow?
Standard 200RB models are uni-directional. While some 200RB valves can be converted with a kit, the 200RB7 and 200RB9 sizes generally do not support bi-flow conversion; always verify the internal configuration for heat pump applications.
What is the purpose of the manual stem on the 200RB7T5M?
The manual lift stem is used by technicians to mechanically open the valve regardless of the coil status, which is vital for pulling a vacuum or bypassing the control system during emergency repairs.
