Q: What is the primary function of the TL317 check valve?
A: The TL317 is a one-way hydraulic component. It enables hydraulic fluid to move freely in the intended direction while automatically blocking any reverse flow. This is crucial for maintaining pressure and preventing system damage caused by backflow.
Q: How does the "cracking pressure" affect performance?
A: The cracking pressure (7.25 PSI) is the minimum amount of pressure required to open the valve. A low cracking pressure like this is beneficial as it minimizes flow restriction, ensuring your hydraulic system operates with maximum efficiency.
Q: Why is the choice of internal materials important?
A: Because internal check valves endure constant mechanical cycling and high-velocity fluid, we utilize hardened and ground steel for these parts. This prevents internal wear, seat erosion, and valve failure over the long term, even under 5000 PSI service.
Q: Can this replace my existing Parker or Prince check valve?
A: The TL317 is designed as a direct replacement for the Parker C800S-M and the Wolverine/Prince WCV-800. Note: We always recommend verifying your specific application requirements or consulting your equipment dealer to ensure a perfect match.
Q: Is there a guarantee on this product?
A: Yes, we stand by our quality; this item comes with a 100% satisfaction guarantee.
