Copeland Comfort Control (Alco) 047504 Solenoid Valve

The Copeland Comfort Control (Alco) 047504 Solenoid Valve is a direct-acting, 2-way normally closed component engineered for rigorous refrigeration service. Designed specifically for liquid line or discharge gas applications, this 100RB2S3 model features a 3/8" ODF sweat connection with extended ends, allowing contractors to braze the valve into the system without the need for disassembly. With a nominal capacity of 1.27 tons for R22 and 1.2 tons for R134a, this valve provides reliable refrigerant shut-off in a compact 1/8" port configuration. The PTFE O-ring ensures a superior external seal against refrigerant leaks, while the rugged construction supports a maximum operating pressure differential (MOPD) of 300 psig and a maximum working pressure of 500 psig. This high-side and low-side compatible valve is a staple for technicians requiring OEM replacement parts that maintain system efficiency and prevent short cycling or slugging in commercial and residential HVACR units.

Key Benefits:

• Universal Coil Compatibility: Uses the standard Alco solenoid coil family (ASC2, AMG), allowing one coil size to fit the entire 100RB valve series.
• Technician-Friendly Installation: Features 3/8" sweat connections with extended ends to protect internal seals during high-heat brazing.
• Broad Refrigerant Support: Highly versatile for use with R22, R134a, R404A, R407C, and R507 systems.
• Direct-Acting Precision: Does not require a minimum pressure differential to operate, making it ideal for low-pressure suction line applications.
• Serviceable Design: Compatible with KS30112 valve repair kits and X11981-1 spanner wrenches for field maintenance.

Common Questions:

Does this valve include the solenoid coil?
No, this is a VLC (Valve Less Coil) model. You must pair it with a compatible Alco ASC2 or AMG coil in the required voltage (24V, 120V, or 208/240V).

Can I install this valve in any orientation?
It is recommended to mount the valve with the enclosing tube in a vertical upright position. Mounting more than 90 degrees off the vertical is not recommended to avoid debris accumulation and plunger sticking.

Is this valve suitable for R410A systems?
While the 100RB series is durable, always verify the MOPD and maximum working pressure (500 psig) against your specific R410A system requirements, as high-pressure systems may exceed these ratings.
