Parker Hannifin Corporation C400S-10LL Check Valve

Parker Hannifin C400S-10LL Check Valve is a high‑pressure hydraulic check valve designed to prevent backflow in fluid power systems. It is rated for up to 5,000 psi and supports flows up to 5 GPM, providing unidirectional flow to protect pumps, actuators, and other components from reverse pressure. Manufactured by Parker Hannifin Corporation, the C400S-10LL carries Parker’s reputation for robust, industrial‑grade hydraulic components and is identified by its model number within Parker’s check valve lineup. This valve is suitable for hydraulic circuits where reliable backflow protection is essential to maintain system pressure and component longevity in demanding applications. The combination of a 5,000 psi rating and 5 GPM flow capacity makes the C400S-10LL a practical choice for moderate to high‑pressure hydraulics requiring straightforward, durable backflow control.
