Description
The ATOS Pressure relief valves type ARE are direct-operated, in-line mounted devices designed to limit maximum pressure in hydraulic systems and protect components from overpressure. Available in models ARE-06 and ARE-15, these valves offer different pressure ranges and options like leak-free execution, lead-sealed regulation, and manual override. They are suitable for various hydraulic fluids and operating conditions, making them versatile for different applications. The datasheet provides comprehensive information on dimensions, materials, performance characteristics, and hydraulic symbols, enabling users to select the appropriate valve for their specific needs.
