Sporlan 311515 MKC-2 Coil

The Sporlan 311515 MKC-2 Coil is a professional-grade 208/240V solenoid coil designed for heavy-duty refrigeration and air conditioning applications. Engineered for use with normally closed solenoid valves, this MKC-2 solenoid coil is an essential component for technicians managing liquid, suction, or discharge line flow. Featuring a built-in junction box, this unit facilitates secure and standardized electrical connections in high-vibration commercial environments. The refrigeration solenoid coil utilizes a high-efficiency copper winding encased in a molded synthetic material, providing superior heat dissipation and moisture resistance for HVACR system maintenance. This specific model is a direct replacement for legacy KC-2 coils, allowing for seamless upgrades to existing valve bodies without extensive re-piping. It operates on 50/60 Hz cycles, delivering 15 watts of power to ensure consistent plunger lift and reliable valve seating under varying pressure differentials.

• Direct Compatibility: Engineered specifically for Sporlan valve series B9, E9, B10, E10, B14, E14, B19, E19, and B25, ensuring precise mechanical fit and operation.
• Integrated Junction Box: Simplifies field wiring and provides a robust housing for electrical terminations, adhering to UL and CSA recommendations for grounding.
• Superior Insulation: Class F insulation ratings allow the coil to handle high ambient temperatures common in industrial refrigeration racks and rooftop units.
• Energy Efficient: Optimized 208/240V dual-voltage performance minimizes inrush current and holding wattage to reduce long-term operational costs.
• Ease of Identification: Features standard red lead wires for rapid voltage identification during multi-circuit service calls.

What is the difference between an MKC-1 and an MKC-2 coil?

The Sporlan solenoid coil service parts are sized by their physical and magnetic capacity. The MKC-1 fits smaller valve bodies like the E3 and S4 series, while the MKC-2 is the larger standard required for higher-capacity valves such as the B19 or E25 series.

Can I use this MKC-2 coil on a normally open valve?

No, this model is designed for normally closed operations. For normally open (NO) valves, the OMKC-2 series must be used to ensure the plunger operates correctly against the spring tension.

Is the junction box required for all installations?

The 311515 model includes an integral junction box for standard commercial wiring. If your application specifically requires a 1/2" conduit boss instead, a different part number from the MKC line would be necessary.
