Refrigeration Solenoid Valve Series
Click a series below to understand its operating design and typical application.
200RE Series – Pilot-Operated Refrigeration Solenoid Valve
The 200RE Series is a pilot-operated, two-way, normally closed electrically operated solenoid valve designed for refrigeration applications.
Suitable service:
- Liquid refrigerant
- Discharge gas
- Suction gas
A versatile option for commercial refrigeration systems requiring electrical ON/OFF refrigerant control.
50RB Series – Compact Direct-Acting Solenoid Valve
The 50RB Series is a direct-acting, two-way, normally closed refrigeration solenoid valve.
Typical service:
- Liquid refrigerant
- Discharge gas
Its direct-acting construction makes it suitable for smaller refrigeration flow-control applications.
100RB Series – Direct-Acting Refrigeration Solenoid Valve
The 100RB Series is another direct-acting, two-way normally closed refrigerant solenoid valve family.
Typical service:
- Liquid refrigerant
- Discharge gas
A proven Copeland / ALCO solution for refrigeration systems requiring dependable electrical refrigerant shut-off.
200RB Series – Pilot-Operated Multipurpose Refrigeration Valve
The 200RB Series is a pilot-operated, two-way normally closed solenoid valve and is one of the most versatile Copeland refrigeration solenoid families.
Suitable service:
- Liquid refrigerant
- Discharge gas
- Suction gas
240RA Series – Normally Closed Diaphragm Solenoid Valve
The 240RA Series is a two-way normally closed diaphragm-type refrigeration solenoid valve.
The family is designed for larger refrigeration flow-control requirements and is used in applications including liquid, suction and hot-gas service depending on model and operating conditions.
500RB Series – Normally Open Refrigeration Solenoid Valve
The 500RB Series provides a normally open solenoid-valve solution for applications where the valve is required to remain open when the coil is not energized.
This operating logic is different from the normally closed 50RB, 100RB, 200RB and 240RA families.
540RA Series – Normally Open Diaphragm Solenoid Valve
The 540RA Series is designed for normally open refrigerant flow-control applications.
Suitable service includes:
- Liquid refrigerant
- Suction gas
- Hot gas

Copeland Solenoid Coil Series
Copeland also provides multiple coil families for its solenoid-valve range. Click below to view the main coil categories.
AMG / AHG Solenoid Coils
AMG / AHG are Copeland coil families designed for compatible solenoid valves. Select the exact coil according to valve series, supply voltage, frequency and electrical connection.
AMC / AHC Solenoid Coils
AMC / AHC coils provide additional electrical configurations for compatible Copeland / ALCO solenoid valves.
AMS / F Solenoid Coils
The AMS / F family forms another part of Copeland's solenoid coil range and should be matched according to the applicable valve and electrical specification.
ASC Solenoid Coils
ASC Series coils feature Copeland's compact coil design and are available in electrical configurations for compatible solenoid valves.
Copeland highlights features including an easy-to-use coil clip, shock and vibration protection and weather-protection options.
MMG Solenoid Coils
MMG is another Copeland solenoid coil family. Always match the coil to the exact valve family, voltage and frequency rather than selecting only by physical appearance.
