Sporlan 101848 Regulator

The Sporlan 101848 A81OES Evaporator Pressure Regulator is a critical component for technicians requiring precise control over suction pressure in commercial refrigeration systems. This externally equalized EPR valve features a 1-3/8" port and 1-5/8" ODF solder connections, providing high flow capacity while minimizing pressure drop across the valve. Designed to prevent evaporator freeze-ups and maintain tight temperature tolerances across multiple evaporators, the Parker Sporlan 101848 operates efficiently in diverse rack systems and air conditioning applications. As a direct cross-reference for the A81OES-1-3/8X1-5/8, this regulator supports various refrigerants and is built with the rugged durability necessary for industrial-grade performance. By regulating the pressure within the evaporator coil, it ensures stable humidity control and prevents the suction pressure from falling below a predetermined setpoint, protecting both product integrity and compressor health.

Technical Benefits:

• Precision Pressure Management: Utilizing an A8-series pressure regulator design, it maintains a constant evaporator pressure regardless of fluctuations in load or suction header pressure.
• Seamless OEM Integration: This genuine Sporlan replacement part ensures exact dimensional matches for 1-5/8" ODF piping, reducing installation time and labor costs for field technicians.
• Broad Refrigerant Compatibility: Engineered to handle modern high-pressure refrigerants, making it a versatile choice for retrofit or new installation projects.
• Robust Serviceability: The ODF solder connections and accessible adjustment nut allow for straightforward calibration and maintenance in the field.

Common Technical Questions:

What is the primary function of the A81OES regulator in a multi-evaporator system?
The Sporlan 101848 is used to maintain a higher pressure in one evaporator while others in the system operate at lower suction pressures, allowing for different temperature zones on a single compressor rack.

Does this model require an external equalizer line?
Yes, the A81OES model is an externally equalized regulator, which allows it to sense pressure downstream of the valve for more accurate control, especially in systems with significant pipe runs.

Can this valve be used as a discharge bypass valve?
While primarily designed as an evaporator pressure regulator, certain Sporlan A8 valves can be configured for other pressure control functions; however, it is recommended to verify specific port sizing and spring ranges for hot gas bypass applications.
