Ranco O16-142 Pressure Control

The Ranco O16-142 Pressure Control is a heavy-duty high-pressure refrigeration control designed for versatile performance in commercial HVACR applications. As a Single Pole Double Throw (SPDT) switch, it provides high-limit protection and operating control for self-contained refrigerators, freezers, and display cases. This model features a robust 100 to 400 PSI range with a factory-set 17 PSI fixed differential, ensuring precise regulation for systems utilizing R-12, R-22, and R-502, as well as being compatible with modern refrigerants like R-134A and R-410A.

Engineered with laser-welded bellows for extended service life, the O16-142 includes a 36-inch capillary with a 1/4-inch SAE flare nut for flexible installation. The NEMA 1 enclosure is fitted with a non-conductive cover and a large, legible scale plate for accurate field adjustments. This unit serves as the direct replacement for P70EA-6, offering a compact design and universal mounting footprint that fits standard M4 or 8-32 UNC hardware, making it a reliable choice for professional contractors seeking to maintain system integrity and discharge-side safety.

• Direct Replacement Compatibility: Specifically designed as an exact match for the Johnson Controls P70EA-6, reducing downtime during field service.
• Enhanced Durability: Features the Super Cap capillary protection system and laser-welded bellows to withstand high-vibration environments.
• Flexible Wiring: The SPDT snap-action switch and raised screw terminals allow for easy field wiring in either pilot duty or direct motor control applications.
• Versatile Refrigerant Support: Suitable for a wide range of high-pressure refrigerants, providing a broad application scope for commercial cooling.

Is the Ranco O16-142 suitable for R-410A systems?
Yes, this pressure control is compatible with high-pressure refrigerants including R-410A, provided the system pressures fall within the 100 to 400 PSI adjustable range.

What is the difference between this and the P70EA-6?
The O16-142 is a cross-referenced equivalent. While the Ranco model utilizes a flare nut connection, it covers the same pressure specifications and functionality as the P70 series.

Can this be mounted in any orientation?
Industrial standards recommend mounting the unit in any position except upside down to prevent debris or oil from accumulating in the sensing element.
