Sporlan 3273-00 MB6F1 Solenoid Valve

The Sporlan 3273-00 MB6F1 Solenoid Valve is a normally closed refrigerant valve designed for tight seating and dependable flow control in commercial refrigeration and air conditioning systems. This model features 3/8 SAE flare connections and a 3/16-inch port, making it a standard choice for technicians managing liquid or suction lines where high-performance pilot-operated disc construction is required. The MB6F1 solenoid includes an integrated manual lift stem, allowing for manual override during system commissioning or emergency troubleshooting when electrical power is unavailable. It is fully compatible with common refrigerants, including R-22, R-134a, R-404A, and R-507.

Engineered for high-pressure environments, the Sporlan MB6F1 supports a safe working pressure of 500 psi and a maximum operating pressure differential (MOPD) of 300 psi for AC applications. This compact solenoid valve requires a minimum pressure drop of 1 psi to ensure the pilot-operated disc opens completely, preventing short-cycling or restricted flow in low-load scenarios. For full installation, pair this body with a Sporlan MKC-1 coil. The 3273-00 is technically identical to the MB6F1, ensuring seamless drop-in replacement for existing Type B6 solenoid valves in the field.

Key Benefits

• Manual Override Capability: The built-in manual lift stem allows technicians to open the valve manually for system evacuation or testing.
• Field-Proven Reliability: Features synthetic seating materials to ensure a bubble-tight seal and prevent internal refrigerant migration.
• Versatile Mounting: This body can be mounted horizontally, on its side, or in vertical lines to fit tight mechanical room configurations.
• Broad Refrigerant Support: Rated for a wide range of gases, covering R-22 and R-404A systems typically found in supermarket and walk-in applications.

Common Questions

Does this valve include the solenoid coil?
No, the Sporlan MB6F1 3/8 SAE is the valve body only. It requires a Sporlan MKC-1 solenoid coil, which must be selected based on your system's voltage requirements.

Can the MB6F1 be used on a suction line?
Yes, its pilot-operated design is suitable for suction line service, provided there is at least a 1 psi pressure differential to actuate the disc.

Is the 3273-00 different from the MB6F1?
No, the 3273-00 is the manufacturer part number and is identical in every specification to the MB6F1 model valve.
