Sporlan 3666-00 / 4147-00 ME25S270 Solenoid Valve

The Sporlan 3666-00, also identified as the 4147-00 ME25S270, is a high-capacity, normally closed solenoid valve engineered for heavy-duty refrigeration and air conditioning applications. This E25 series valve features a 7/8" ODF sweat connection and is designed as a pilot-operated disc valve, ensuring reliable performance in liquid, suction, or hot gas service lines. As a direct replacement for the ME25S270, the 4147-00 utilizes a high-pressure (HP) construction capable of handling modern high-pressure refrigerants. The synthetic seating material provides tight shut-off, preventing refrigerant migration during the off-cycle. For contractors performing system retrofits or repairs, this Sporlan solenoid valve offers superior durability in demanding environments. Its compatibility with the MKC-2 coil ensures seamless integration with existing electrical control circuits. When installing, ensure proper heat sinking to protect the internal components during the brazing process, maintaining the integrity of the solenoid valve body and long-term system stability.

• Extended Service Life: Constructed with premium grade materials to resist corrosion and mechanical wear in commercial refrigeration solenoid applications.
• Versatile Application: Suitable for discharge gas, liquid line, and suction line service, offering flexibility for multifaceted mechanical projects.
• Field Serviceable: Designed for easy access to internal components, simplifying maintenance and reducing downtime for HVACR contractors.

Common Questions

Is the 4147-00 compatible with older ME25S270 installations?
Yes, the 4147-00 is the designated direct replacement for the ME25S270 solenoid valve, maintaining identical port sizing and 7/8" sweat connection dimensions for a drop-in fit.

What coil should be used with this Sporlan valve body?
This valve body is typically paired with Sporlan MKC-2 series coils. Always verify voltage and frequency requirements of the specific control circuit before selecting the coil.

Can this solenoid valve be installed in any orientation?
For optimal performance and to prevent debris accumulation, it is recommended to install the valve in a horizontal line with the coil housing in the upright vertical position.
