Sporlan 168005 QE 3X4 SAE Body

The Sporlan 168005 QE 3X4 SAE Body is a professional-grade thermostatic expansion valve body engineered for high-precision refrigerant metering in commercial refrigeration and air conditioning systems. This externally equalized TXV body features a 3/8" SAE flare inlet and a 1/2" SAE flare outlet, providing a secure, metal-to-metal knife-edge joint that ensures leak-proof performance under high-pressure conditions up to 450 psi. As part of the versatile Sporlan Q series, the 168005 utilizes a replaceable cartridge design, allowing technicians to field-service the valve or swap orifices to match specific system loads without breaking the line. The external equalizer connection, sized at 1/4" SAE, is essential for maintaining accurate superheat control in systems with significant pressure drops across the evaporator. Built with a robust brass body, it is compatible with a wide range of refrigerants including R-22, R-404A, and R-134a, making it a reliable choice for supermarket cases, walk-in coolers, and transport refrigeration units.

• Replaceable Cartridge Design: Facilitates rapid serviceability and capacity adjustments without removing the valve body from the system.
• Externally Equalized Control: Delivers precise superheat management, critical for evaporators with high pressure drop or large distributors.
• Knife-Edge Construction: Features Sporlan's signature metal-to-metal thermostatic element-to-body seal for long-term refrigerant containment.
• High-Pressure Rating: Designed for demanding environments with a maximum working pressure of up to 450 psi.
• Integrated Strainer: Includes a 100-mesh removable inlet strainer to protect the internal orifice from system debris.

Is the cartridge included with the 168005 body?
No, the 168005 is the valve body only. The replaceable cartridge and thermostatic element are sold separately to allow for custom system configuration.

Can this body be used for R-410A systems?
This specific SAE flare body is rated for up to 450 psi. For high-pressure R-410A applications, verify the total system operating pressure against the valve's technical limits; typically, ODF sweat versions are preferred for R-410A high-side pressures.

What is the purpose of the 1/4" SAE connection?
This is the external equalizer port. It must be connected to the suction line near the sensing bulb to allow the TXV to compensate for the evaporator's pressure drop.
