🗸 TL317 1/2" NPT HYDRAULIC IN-LINE CHECK VALVE – A high-performance, unidirectional flow control solution engineered for heavy-duty hydraulic systems. Rated for 5000 PSI, this valve ensures precise flow regulation and system protection.

🗸 PRECISION DIRECTIONAL CONTROL: Designed to allow free, unrestricted flow in one direction while providing an immediate, reliable seal against reverse flow, protecting your pumps and system components from pressure backflow.

🗸 INDUSTRIAL-GRADE CONSTRUCTION: Built with a robust zinc-plated steel body and precision-machined, hardened and ground steel internal components to ensure longevity and high-cycle performance in demanding industrial environments.

🗸 OPTIMIZED FOR EFFICIENCY: Features a low cracking pressure of 7.25 PSI, ensuring the valve opens effortlessly to allow flow while maintaining an efficient maximum flow capacity of 13 GPM.

🗸 DIRECT COMPATIBILITY: An ideal replacement for industry-standard valves, including the Parker C800S-M and Prince/Wolverine WCV-800 series.

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.
