What is the maximum pressure range for the PA4 brake cylinder?

The PA4 brake cylinder is designed with a specific operational pressure range that is crucial for its effective functionality in braking systems. The correct answer indicates that the maximum pressure range for the PA4 brake cylinder is between 0-60 to 62 psi. This range ensures that the brake system can operate safely and effectively under typical conditions while preventing failure due to over-pressure.

Understanding the correct pressure range is essential for maintaining brake performance and safety in various applications. Operating outside this range could lead to inadequate braking ability or potential failure of the brake system, which is critical for vehicle safety and reliability.

The other options provide different pressure ranges that do not align with the specifications of the PA4 brake cylinder design. Knowing the correct specifications allows engineers and technicians to perform accurate maintenance and adjustments, ensuring optimal performance in operations involving this brake cylinder.
