Bard 5651-242 Thermostatic Expansion Valve 3/8 x 3/8 Inch

The Bard 5651-242 is a thermostatic expansion valve (TXV) designed to regulate refrigerant flow in commercial and residential HVAC systems. This precision-engineered component controls the amount of refrigerant entering the evaporator coil by monitoring superheat conditions, ensuring optimal system performance and energy efficiency.

Key Features:

• 3/8 inch x 3/8 inch connection size for standard refrigerant line integration
• Sensing bulb monitors system conditions and adjusts refrigerant expansion accordingly
• Maintains balanced refrigerant flow for efficient cooling and heating operation
• Prevents overfeeding or underfeeding of refrigerant to protect compressor from liquid floodback
• Durable brass construction for corrosion resistance and long service life
• Compatible with multiple refrigerant types commonly used in HVAC applications

This genuine Bard replacement part is engineered to meet OEM specifications for wall-mounted packaged units, heat pumps, and air conditioning systems. The thermostatic expansion valve plays a critical role in system efficiency by precisely metering refrigerant based on real-time temperature conditions, helping maintain proper superheat levels and extending equipment lifespan.
