Sporlan 168191 BQ 2X4 SAE Body

The Sporlan 168191 BQ 2X4 SAE Body is a professional-grade thermostatic expansion valve body designed for technicians requiring a reliable, balanced port expansion valve to handle fluctuating head pressures and varying load conditions. This TXV valve body features 1/4" SAE flare inlet and 1/2" SAE flare outlet connections, allowing for a secure, leak-proof metal-to-metal joint using Sporlan's traditional knife-edge construction. As a replaceable cartridge style valve, it offers maximum field flexibility, allowing contractors to customize the capacity and thermostatic charge to match specific refrigeration or air conditioning requirements. The internal equalizer design simplifies installation in systems without significant evaporator pressure drops, making it a staple for light commercial refrigeration, coolers, and heat pump duty. Engineered for durability, this brass metering device supports a maximum operating pressure of 450 psi, ensuring stable superheat control and preventing liquid slugging to protect the compressor in bi-directional or standard applications.

Key Benefits

• Balanced Port Design: Compensates for shifting operating pressures, providing precise refrigerant metering even during low-load conditions.
• Interchangeable Cartridge System: Allows for quick capacity adjustments and simplified inventory management by using one body for multiple tonnages.
• SAE Flare Connections: Facilitates a robust mechanical connection without the need for brazing, ideal for rapid field replacements.
• Internal Equalization: Streamlines the piping process for compact systems, reducing the number of external leak points.
• Charge Migration Resistance: The top-entry liquid flow design warms the thermostatic element to maintain consistent bulb control and prevent migration.

Common Questions

Can I use this body for both air conditioning and low-temp refrigeration?
Yes, the Sporlan 168191 is compatible with various systems; however, the final application is determined by the specific cartridge and thermostatic element you select for the refrigerant and temperature range required.

Does this valve body support bi-directional flow?
The BQ series is engineered for bi-directional applications, making it an excellent choice for heat pump systems that require precise flow control in both heating and cooling modes.

Is the superheat adjustable on this BQ body?
Yes, this body features an adjustable superheat stem. It is recommended to allow the system to stabilize for at least 15 minutes after making manual adjustments to ensure accurate readings.
