Emerson Flow Control (Alco) Refrigeration Solenoid Valve ODF Manual Stem

The Emerson Flow Control (Alco) 200RB series refrigeration solenoid valve with manual stem is a pilot-operated, 2-way normally closed valve. It gives reliable on/off control of refrigerant in commercial refrigeration, air conditioning and HVACR systems. These ODF sweat-connection solenoid valves are used on liquid, suction and discharge gas lines. Technicians may also know them as A/C solenoid valves, refrigerant shut-off valves or solenoid valve bodies.

Key Features:

• Integrated manual stem: lets you open the valve by hand during system evacuation, charging, troubleshooting or a power failure.
• ODF sweat connections: copper extended ends make brazing easier and help keep torch heat away from the valve's internal seals, so you don't need to disassemble the valve.
• Pilot-operated design: opens reliably at low pressure differentials.
• PTFE O-ring: seals the valve externally to help prevent refrigerant leaks.
• Multi-refrigerant compatibility: suited to common refrigerants such as R22, R134a and R404A.
• Single coil family: one coil family fits the 200RB series, which simplifies truck stock and field replacements.
• Serviceable: repair kits are available for the series.

Alco is known for engineering focused on system efficiency and long-term reliability. These valves suit contractors and technicians who maintain commercial refrigeration racks, split-system HVAC equipment and industrial cooling systems. The valve body is sold separately from the coil.
