Bard 800-0255 TXV
The Bard 800-0255 Thermostatic Expansion Valve (TXV) is a critical metered flow component designed for high-efficiency refrigerant management in specific Bard HVAC systems. This 3/8 x 3/8 ODF valve utilizes a balanced port design to maintain a constant superheat across varying evaporator loads, ensuring the compressor is protected from liquid slugging while maximizing coil heat transfer efficiency. Constructed for R-410A refrigerant systems, it features a stainless steel power element and a copper capillary tube to resist corrosion and vibration fatigue common in wall-mount heat pumps and air conditioners. For contractors performing a field replacement, the 1/2-inch hex nut and internal check valve allow for precise flow control during both cooling and heating cycles. This OEM-spec expansion valve is the direct replacement part for maintaining the factory-rated SEER and EER performance of Bard equipment, providing the modulation necessary for stable suction pressure during low-ambient operation.
Key Benefits for Technicians:- Optimized Superheat Control: Maintains precise refrigerant flow to prevent evaporator freeze-ups and ensure motor cooling.
- Balanced Port Construction: Compensates for changes in head pressure, providing stable operation across a wide range of ambient temperatures.
- Internal Check Valve: Specifically engineered for heat pump applications to allow reverse flow without bypass piping.
- Durable Hermetic Design: Laser-welded stainless steel diaphragm ensures long-term reliability and leak prevention in high-pressure R-410A circuits.
- Direct OEM Fitment: Eliminates the need for field modifications or line-set adjustments during HVAC valve replacement.
What are the connection sizes for the Bard 800-0255?
This TXV features 3/8" ODF (Solder) connections for both the inlet and outlet, facilitating a standard brazed installation into the liquid line and evaporator distributor.
Is this valve compatible with R-22 systems?
No, the Bard 800-0255 is calibrated specifically for the pressure-temperature curves of R-410A. Utilizing this valve with R-22 will result in incorrect superheat levels and potential compressor damage.
Does this TXV include the sensing bulb insulation?
Standard field practice requires reusing or replacing the bulb insulation tape; while the bulb is attached via the capillary tube, proper insulation against the suction line is required for accurate temperature sensing.
