Sporlan 311671P Coil

The Sporlan 311671P Coil is a professional-grade MKC-2 solenoid coil engineered for heavy-duty refrigeration and air conditioning applications. Optimized for 120/240V dual-voltage operation at 15 Watts, this normally closed solenoid coil provides the necessary linear motion to actuate valve plungers in high-pressure industrial environments. This specific MKC-2 model is designed for compatibility with a broad range of Sporlan valves, including the E9, E10, E14, E19, and E25 series, as well as several pressure-regulating valves like the SHGB-15 and OLDR-15. The 4-wire configuration, housed within an integral junction box, ensures a secure electrical termination and simplified field wiring for service technicians. Built with Class F insulation, the Sporlan 311671P handles the high ambient temperatures common in mechanical rooms and rooftop units, maintaining reliable refrigerant flow control without premature thermal degradation. Whether you are performing a solenoid coil replacement or a new system startup, this genuine Parker Sporlan component delivers the precise magnetic force required to overcome internal pressure differentials in liquid, suction, or hot gas lines.

• Dual-Voltage Versatility: Direct 120/240V compatibility reduces truck stock requirements and ensures local power match for varied HVACR sites.
• Broad Valve Compatibility: Drops directly onto MKC-2 series valve bodies, including larger tonnage B and E series normally closed valves.
• Enhanced Durability: Molded construction with 15-Watt rating provides the robust pull-in power needed for high-pressure 410A and CO2 systems.
• Integrated Junction Box: Includes a factory-installed junction box with grounding provisions, meeting standard electrical code requirements for commercial installs.

Is this coil compatible with normally open (N.O.) valves?
No, the 311671P is specifically engineered for normally closed valves. Utilizing this coil on an OMKC series normally open valve will lead to improper seating and potential coil burnout.

What causes this coil to buzz or hum after installation?
Audible humming typically indicates an undervoltage condition or debris preventing the plunger from fully seating in the core tube. Ensure the supply voltage is within ±10% of the 120/240V rating and that the armature is clear of metal shavings or sludge.

Can I use this to replace an older KC-2 style coil?
Yes, the modern MKC-2 molded series is the direct functional replacement for the legacy metal-housed KC-2 coils. When upgrading, discard the old housing and use the new molded assembly as a complete unit.
