SUN Hydraulics CNCE-XCN | Pilot-to-Open Check Valve

SUN Hydraulics CNCE-XCN Pilot-to-Open Check Valve

Product Overview:

The SUN CNCE-XCN is a threaded cartridge, pilot-to-open check valve (often referred to as a pilot-operated check valve), designed as a critical component for load holding and safety locking in hydraulic systems. It allows free flow from Port 2 to Port 1 while preventing reverse flow until pressure is applied to the pilot port (Port 3). Fitting into the standard T-11A cavity, the CNCE-XCN is renowned for its ultra-low leakage and high structural integrity, making it a staple for crane outriggers, excavator cylinders, and any machinery requiring long-term pressure retention.

We provide both Original Genuine and High-Quality Factory Supply options to meet your specific performance and budgetary requirements.

Key Technical Advantages:

• Zero-Leakage Load Locking: Features hardened steel spools and seats to ensure zero leakage in the locked position, preventing unintended cylinder drift.

• Reliable Pilot Modulation: A standard 3:1 pilot ratio ensures smooth unlocking performance even under volatile pressure fluctuations.

• Rugged Cartridge Construction: Fits standard SUN T-11A cavities; the threaded design ensures no loosening or seepage in high-vibration environments.

• Flexible Sourcing Options: We guarantee original authenticity alongside cost-effective factory alternatives, all 100% tested for pressure and sealing integrity.
