Description
The Sporlan Controls 168191 Thermostatic Expansion Valve BQ-Body-2X4SAE is a replaceable cartridge valve body used in refrigeration and air conditioning systems to regulate refrigerant flow into the evaporator in HVAC systems. It is placed in display cases, walk-in coolers, freezers, and heat pump systems where precise superheat control is required for stable cooling performance. It operates as the metering section of the assembly, working with a thermostatic element to adjust flow based on load conditions. It helps to maintain consistent operation under varying pressures, supporting efficient evaporator and compressor control in applications of the systems.
