Copeland 510-7002-54 Solenoid Valve

The Copeland 510-7002-54 is an OEM solenoid valve with a 120 V coil for refrigerant flow control in refrigeration and air conditioning circuits. The photo shows the complete assembly: a cast brass valve body with copper sweat connection stubs on each side, a Copeland coil, type AMC, held on the valve with a spring retaining clip, and a jacketed two-conductor lead with a cable tie. The coil label reads 120 volts, 17/12 watts (inrush and holding), 50/60 Hz, coil assembled in Mexico, and carries the 510-7002-54 number alongside the factory code GS-2214-3.

A solenoid valve is an electrically operated shutoff: current in the coil creates a magnetic field that moves an internal plunger to open or close the valve port, giving the system a clean on/off control of refrigerant flow without a mechanical linkage. It is used where a circuit must be isolated or released on a signal from a thermostat, pressure control or controller, which also helps protect the compressor from flooding and keeps unwanted refrigerant migration out of the evaporator during the off cycle. This 510-7002-54 is the 120 V version; the 208-240 V version in the same Copeland series is 510-7002-31, so verify the control voltage in your circuit before ordering, because a coil on the wrong voltage will either not pull in or will burn out quickly.

The usual failures are an open or shorted coil (no magnetic click when energized, a hot or discolored coil, or a tripped control circuit) and a valve that sticks or leaks by because of debris or wear. First confirm the correct voltage at the coil leads, listen or feel for the plunger action when the circuit is energized, and check the coil with a meter before replacing the whole valve. Never energize a coil that is off the valve body, because it overheats within moments. Replacing the valve is a sealed-system repair: recover the refrigerant per EPA Section 608 practice, remove the coil from the body and protect the valve body from heat while brazing, then pressure test, evacuate and recharge before returning the system to service. Mount the valve in the orientation the original used so the plunger works as designed.

Key Benefits

• Complete Valve and Coil Assembly: Pictured as a factory unit with the Copeland AMC coil, retaining clip, lead wire and sweat stubs already assembled.
• 120 V Control: The 120 volt, 17/12 watt, 50/60 Hz coil is the right fit where the control circuit is line-voltage 120 V.
• Positive On/Off Refrigerant Control: Gives the circuit repeatable isolation and release on command from the system controls.
• Copeland OEM Part: Factory 510-7002-54 labeling and construction, with the -31 (208-240 V) sibling available when your control voltage differs.

Common Questions

• What voltage is the coil? The coil on the Copeland 510-7002-54 is labeled 120 volts, 17/12 watts, 50/60 Hz.
• Is this the same as 510-7002-31? No. 510-7002-31 is the 208-240 V version in the same series; 510-7002-54 is the 120 V version.
• Can I replace just the coil? If the coil is the only failed component and the valve opens and closes properly, a matching Copeland coil may be all you need; if the valve body is stuck or leaking, replace the full valve assembly.
