Sporlan 903031P Pressure Control
The Sporlan 903031P Pressure Control Valve, also identified as the Parker Sporlan LAC-4-100, is a high-performance low ambient head pressure control designed for small-capacity refrigeration and air conditioning systems. This three-way modulating valve maintains stable liquid line pressure by restricting refrigerant flow from the condenser while simultaneously bypassing hot gas directly to the receiver during low outdoor temperatures. By effectively flooding the condenser, the LAC-4-100 ensures that the expansion valve receives sufficient pressure to feed the evaporator, preventing suction pressure drops and coil freeze-ups in demanding conditions. Built with a brass body and 1/2" ODF copper connections, this 100 PSI factory-set control is optimized for R-134a systems and other compatible refrigerants. Its non-adjustable, compact design makes it a reliable choice for contractors looking to maintain system efficiency in walk-in coolers, freezers, and remote condensing units without the need for complex electronic controls.
Key Benefits for HVACR Professionals
- Consistent Head Pressure Management: Automatically modulates to maintain a 100 PSI setpoint, ensuring proper refrigerant flow during low ambient operation.
- Simplified Installation: Features 1/2" ODF solder connections and a compact footprint for quick integration into existing commercial refrigeration circuits.
- Rugged Reliability: Engineered with a sensitive diaphragm and a brass body for durable performance in harsh outdoor environments.
- Optimized for R-134a: The 100 PSI setting is specifically designed to provide the necessary pressure drop for TXV operation in medium and high-temperature applications.
- Eliminates Short Cycling: Prevents low-pressure trip-outs and unstable compressor operation caused by fluctuating ambient temperatures.
Common Questions About the LAC-4-100
What refrigerant is the LAC-4-100 best suited for?
While often utilized with R-134a due to its 100 PSI factory setting, it is also compatible with other refrigerants where a 100 PSI liquid line pressure is appropriate for the system's design.
Is the Sporlan 903031P adjustable in the field?
No, the LAC-4 series is a non-adjustable, factory-set valve. If you require field adjustment, consider the Sporlan ORI/ORD combination valves.
Does this valve require an external power source?
No, the Parker Sporlan LAC-4-100 is a strictly mechanical modulating valve that responds to discharge pressure, requiring no electrical wiring or external controllers.
