Sun Hydraulics CSAD-XXN Cartridge Valve 20 GPM 5000 PSI 1/4 Inch Threaded Mounting

The Sun Hydraulics CSAD-XXN Cartridge Valve is a 100% new original hydraulic valve designed for high reliability and precision flow control. This 1/4 inch valve delivers up to 20 gpm flow rate with exceptional durability exceeding 5 million cycles.

• High Reliability Design: Floating valve tail reduces sensitivity to installation torque and prevents component sticking
• Optimized Flow Capacity: Thread shoulder flat design disperses stress and reduces eccentricity impact
• Precision Sealing: O-ring guide angle with 63Ra surface finish prevents leakage
• Modular Construction: Saves installation space and allows valve core replacement without pipe disassembly
• Extended Service Life: Heat-treated components with excellent wear resistance (≥5 million cycles)
• Low Maintenance: No additional grease required; only periodic seal checks needed

• Inspect threaded areas for damage before installation
• Align control cover with oil port/pins precisely
• Use high-strength screws (grade 10.9/12.9) and tighten in stages
• Maintain oil cleanliness to NAS 1638 Level 6 standard
• Drain system and inject anti-rust oil before long shutdowns
• Use only original replacement parts for maintenance

• EPDM seals compatible with phosphate ester media only
• Operating temperature range: -60℃ to 120℃
• For extreme temperatures, use fluororubber seals
• Avoid petroleum-based hydraulic oils with EPDM seals
