Sporlan 168186 EBQE Valve Body

The Sporlan 168186 EBQE Valve Body is a professional-grade, externally equalized expansion valve component engineered for high-pressure R410A refrigeration and air conditioning systems. Designed as part of the versatile BQ series, this brass body features 3/8" x 1/2" ODF extended connections that simplify the brazing process for contractors while ensuring a leak-proof, metal-to-metal knife-edge joint. The balanced port construction is specifically built to handle systems with widely varying operating conditions, providing precise pin and port alignment that prevents liquid pressure fluctuations from affecting valve performance. This bi-directional capable body requires a compatible replaceable cartridge and thermostatic element to complete the assembly, allowing technicians to tailor the superheat control to specific evaporator requirements. With a design working pressure of 700 psi for R410A applications and an integrated 100-mesh insert strainer, this Sporlan EBQE body is the reliable choice for maintaining system stability and preventing compressor slugging in residential and commercial chillers.

• Balanced Port Design: Compensates for changes in head pressure, ensuring consistent superheat control across a wide range of ambient temperatures.
• Interchangeable Components: Allows for field-replaceable cartridges and thermostatic elements, reducing inventory bulk and increasing system flexibility.
• R410A Optimized: Rated for high-pressure operation up to 700 psi, making it compatible with modern high-efficiency HVAC equipment.
• Extended ODF Connections: Provides easier access for torch work and reduces the risk of internal component damage during installation.
• Debris Protection: Includes a 100-mesh insertable strainer to protect the orifice from contaminants in the liquid line.

Does this valve body include the internal cartridge or powerhead?
No, the 168186 is the valve body only. To complete the installation, you must size and install the appropriate Sporlan cartridge and thermostatic element based on your system tonnage and refrigerant type.

Where should the external equalizer line be connected?
It should be connected to the suction line immediately downstream from the thermostatic sensing bulb to ensure the valve receives an accurate pressure signal for precise superheat regulation.

Can this valve be used for heat pump applications?
Yes, the EBQE series features a balanced port design that supports bi-directional flow, making it suitable for use in heat pump systems where refrigerant flow reverses during the heating cycle.
