Sporlan 3394-00 ME9S240 Valve

The Sporlan 3394-00 ME9S240 is a heavy-duty, normally closed (N/C) solenoid valve engineered for precision refrigerant flow control in high-pressure commercial HVACR systems. Built with a 1/2" ODF sweat connection, this E9 series valve features a brass body and extended copper tails to simplify brazing without risk of internal component damage. As the direct replacement for the Sporlan 3396-00, it maintains a compact footprint while offering a high MOPD (Maximum Operating Pressure Differential) suitable for liquid, suction, or hot gas service. The ME9S240 is compatible with all major CFC, HCFC, and HFC refrigerants, including R-22, R-134a, and R-404A. This pilot-operated valve ensures tight shut-off and reliable opening under full load conditions, making it a critical component for maintaining system efficiency and protecting compressors from liquid migration during off-cycles. Its rugged construction is designed to withstand the vibration and thermal cycling common in supermarket refrigeration and large-scale rooftop units.

Key Performance Benefits

• Direct Replacement: Specifically engineered to replace the obsolete Sporlan 3396-00 with identical porting and capacity.
• Versatile Application: Qualified for liquid line, suction line, and hot gas defrost applications across multiple refrigerant types.
• Reliable Seating: Synthetic seating material ensures a positive seal, preventing bypass and improving system superheat control.
• Contractor Friendly: The 1/2" sweat connection eliminates the need for extra fittings, reducing potential leak paths in the refrigeration circuit.
• Pilot-Operated Efficiency: High-pressure capability allows for consistent operation even in systems with fluctuating head pressures.

Common Technical Questions

Does this valve include the solenoid coil?
The ME9S240 is the valve body only. You must pair it with a standard Sporlan MKC-1 or OMKC-1 coil depending on your voltage requirements.

Can the ME9S240 be mounted in any orientation?
For optimal performance, the valve should be mounted in a horizontal line with the coil in an upright position. Mounting it upside down can lead to debris accumulation in the pilot assembly.

Is this valve compatible with R-410A systems?
Yes, the ME9S240 is rated for the high-pressure demands of R-410A, provided the system's operating pressure does not exceed the valve's maximum rated pressure.
