Sporlan 101910 Regulator

The Parker Sporlan 101910 A81OE is a high-capacity outlet pressure regulating valve designed to maintain a constant downstream pressure regardless of fluctuations in the inlet pressure or load. As a critical component in commercial and industrial refrigeration, this externally equalized regulator features a 1-3/8" ODF connection and a 1-3/8" port, providing precise modulation for evaporator pressure control. Built for high-pressure applications, it supports a range from 10 in-Hg up to 400 psig, effectively preventing compressor overload during pull-down or after defrost cycles.

This Sporlan A81OE regulator is engineered for technicians who require OEM-grade refrigeration valves that offer stable performance in demanding HVACR environments. The external equalization feature allows the valve to react to the actual pressure at the evaporator outlet, ensuring accurate temperature management and system efficiency. Whether used for hot gas bypass or head pressure control, the 101910 ensures consistent refrigerant flow and protects the suction line from excessive pressure spikes.

Key Benefits for the Contractor:

• Precision Pressure Modulation: Maintains consistent outlet pressure to protect downstream components and improve system stability.
• High Reynolds Number Flow: The 1-3/8" port size handles significant refrigerant volumes with minimal pressure drop across the seat.
• Robust OEM Construction: Genuine Parker Sporlan metallurgy ensures compatibility with modern refrigerants and oils in heavy-duty cycles.
• Simplified Field Calibration: Accessible adjustment screw allows for fine-tuning the pressure setting within the 0 to 400 psig range.
• Reliable Externally Equalized Design: Compensates for pressure drops through the evaporator, ensuring the most accurate set-point response.

Common Questions:

What is the primary application for the Sporlan A81OE?
It is primarily used as a crankcase pressure regulator (CPR) or an evaporator pressure regulator (EPR) to limit the pressure to the compressor suction or maintain a minimum evaporator pressure.

Does this valve require an external sensing line?
Yes, as an externally equalized regulator, it requires a 1/4" ODF connection to the suction line downstream of the valve to accurately sense and regulate pressure.

Is the 101910 compatible with high-pressure refrigerants?
Yes, the A81 series is rated for a maximum rated pressure of 450 psig, making it suitable for most R-404A, R-407C, and R-507 applications.
