Sporlan Controls 3552-00 Solenoid Valve

The Sporlan Controls 3552-00 Solenoid Valve is a 7/8" ODF, 2-way, normally closed solenoid valve engineered for precision refrigerant flow control in commercial HVACR systems. This pilot-operated valve body is the primary replacement for 064765 and is designed for liquid, suction, and discharge gas applications. Built with a rugged forged brass body and extended copper connections, the Sporlan 3552-00 allows for brazing without disassembly, saving significant time on the job site. It utilizes synthetic seating materials to ensure a tight, leak-free seal even in low-pressure differential environments. Note that this specific model is a "less coil" assembly, meaning a compatible electrical coil must be matched to your system voltage for operation. Crucially, as per manufacturer guidelines, the 3552-00 is not rated for R410A high-pressure service; verify your system refrigerant—such as R22 or R134a—before installation to ensure safe MOPD performance.

Key Benefits

• Direct Replacement Logic: Serves as the official replacement for 064765, ensuring fitment in existing racks and units.
• Extended Solder Connections: The E-series design features 7/8" ODF copper stubs, allowing technicians to braze the valve into the line without internal component teardown.
• Low Pressure Drop: Being pilot-operated, this valve requires minimal pressure differential for full opening, making it ideal for suction line service.
• Durable Sealing: Equipped with synthetic seating and metal gaskets to prevent external leaks and ensure positive shut-off.
• Mounting Versatility: Can be installed in horizontal, vertical, or side-mounted positions to fit tight mechanical room configurations.

Common Questions

Is the coil included with the Sporlan 3552-00?
No, this is a "less coil" body. You must select a separate MKC-2 solenoid coil that matches your specific control circuit voltage (e.g., 24V, 120V, or 208/240V).

Can I use this 3552-00 valve for R410A systems?
No. Technical data explicitly states this model is not for R410A use. For high-pressure R410A applications, you must use the HP-rated series like the ME25S270-HP.

What is the flow orientation for this valve?
As a 2-way normally closed valve, it must be installed with the flow in the direction of the arrow on the valve body to ensure the pilot-operated disc functions correctly against system pressure.
