Emerson Alco 052726 Solenoid Valve

The Emerson Alco 052726, also identified as the 200RB3F3, is a high-performance pilot-operated refrigeration solenoid valve designed for liquid, suction, and hot gas service. This 2-way normally closed valve features 3/8" flare connections, providing a reliable seal for high-pressure refrigeration cycles. Engineered for versatility, it handles an R22 capacity of 4.8 tons and an R134a capacity of 3.6 tons at standard conditions. The valve body's extended copper ends or flare fittings allow for straightforward installation, while the pilot-operated diaphragm ensures stable operation even at low pressure differentials. Built to withstand rugged field conditions, the 200RB series is compatible with common HCFC and HFC refrigerants. This HVAC solenoid valve body requires no disassembly for soldering and utilizes a short-stroke design to minimize wear and extend service life in demanding commercial refrigeration systems.

Key Benefits for Technicians:

• Broad Refrigerant Compatibility: Rated for use with R-22, R-134a, R-404A, and R-507.
• High Flow Efficiency: Optimized internal porting provides maximum BTUH capacity for 3/8" flare solenoid applications.
• Serviceability: Features a snap-on coil design and top-entry internal parts for rapid field maintenance.
• Durable Construction: Stainless steel enclosed magnetic plunger prevents sticking and corrosion.
• High MOPD: Capable of opening against high pressure differentials, crucial for hot gas bypass and liquid line shutoff.

Common Installation and Application Questions:

Does this valve include the solenoid coil?
No, this is a valve body only. You must pair it with a compatible Emerson AMC or ASC2 series coil, ensuring the voltage matches the system control circuit.

Can the 200RB3F3 be mounted in any orientation?
While the valve can be mounted in various positions, it is best practice to install it with the coil upright to prevent debris from settling in the plunger tube.

What is the maximum fluid temperature rating?
The 200RB series is designed to handle fluid temperatures up to 250°F, making it suitable for discharge line applications.
