What can be removed from the strainer orifice used on the 50AF-2 pressure relief valve?

The primary jet in the strainer orifice of the 50AF-2 pressure relief valve can be removed to facilitate maintenance and ensure proper functionality. The primary jet serves as the main flow control point within the system, and removing it allows for cleaning or inspection, which is critical for preventing clogs that could impede the valve's performance.

While the secondary jet plays a role in providing additional flow capacity or pressure relief under certain conditions, it typically does not require removal during routine maintenance as its design supports the operation of the primary jet. Hence, focusing on the primary jet for removal aligns with standard maintenance protocols aimed at promoting valve reliability and efficiency. This focused approach helps in keeping the system clean without inadvertently disrupting the secondary components that may not need servicing as frequently.

Considering these factors, the emphasis on the primary jet reflects an understanding of the operational mechanics and maintenance practices associated with the 50AF-2 pressure relief valve.
