The Sun CAEALHN is a high-performance, pilot-operated, balanced piston relief valve designed for precise pressure limiting in hydraulic circuits. Its balanced piston construction ensures that it is largely insensitive to back-pressure at the outlet port, providing stable and consistent performance. This cartridge valve is engineered for applications requiring a low pressure rise and smooth operation, effectively protecting hydraulic systems from over-pressurization. The CAEALHN fits into a standard T-11A cavity, making it a versatile and reliable choice for a wide range of industrial and mobile hydraulic applications.
