Description
The Sporlan Controls 3424-00 is a normally closed (N/C) refrigeration solenoid valve featuring a 5/8″ ODF connection, sold less coil. Designed for use in commercial and industrial HVAC/R applications, this valve remains closed in its de-energized state, providing a fail-safe shutoff of refrigerant flow whenever power is interrupted. The less-coil configuration allows technicians to pair this valve body with a compatible Sporlan coil, offering flexibility when replacing valve bodies or upgrading existing systems without changing the coil assembly.
Key Features
- Normally closed (N/C) operation — valve closes automatically when de-energized for fail-safe refrigerant shutoff
- 5/8″ ODF connection for straightforward copper tubing integration
- Sold less coil — compatible with a range of Sporlan replacement coils for flexible installation
- Engineered for reliable performance in refrigerant liquid, suction, and hot gas line applications
- Durable construction built to Sporlan’s industry-leading quality standards
- Ideal for use in refrigeration systems, air conditioning equipment, and heat pump applications
Application
The Sporlan 3424-00 solenoid valve is well-suited for controlling refrigerant flow in a variety of HVAC/R systems, including commercial refrigeration cases, condensing units, and air conditioning systems. The normally closed design ensures that refrigerant flow is automatically stopped during power outages or system shutdowns, protecting equipment and maintaining system integrity.
Installation Notes
- Valve body only — a compatible Sporlan coil must be ordered separately
- 5/8″ ODF sweat connections for standard copper line set integration
- Always verify coil voltage and amperage ratings match your system requirements before installation
- Install in accordance with all applicable local codes and manufacturer guidelines
