Overview and Main Features<\/h3>\n

The AMI secondary valves<\/strong> constitute a complete line of accessories for hydraulic directional control valves, designed to ensure safety and pressure control in hydraulic circuits. These components are essential to protect the systems from overloads, shocks, and cavitation phenomena, ensuring the efficiency of the actuators connected to the ports. The range is divided into various specific configurations for ports A and B, offering versatile solutions for multiple application needs.<\/p>\n

Pressure Relief and Anti-shock Valves<\/h3>\n

Pressure peak control is managed through various valve variants, designed to operate on specific lines or in combination. The Z6 and Z7 models operate as pressure relief and anti-shock valves on port A (Z6) and port B (Z7) respectively. Similarly, the Z48 and Z49 variants offer the same dedicated protective function, with Z48 on port A and Z49 on port B. For applications requiring simultaneous protection, the Z50 valve acts as a maximum pressure relief valve on both ports A and B. Furthermore, the Z13 configuration provides a maximum pressure function on ports A – B integrated with cross-over relief.<\/p>\n

Anti-Cavitation Valves<\/h3>\n

To prevent damage caused by fluid depression and the formation of air bubbles, the series includes specific anti-cavitation valves. The Z12 model acts as a general anti-cavitation valve for the entire circuit. For targeted control, the Z8 and Z9 variants ensure the anti-cavitation function independently, operating on port A (Z8) and port B (Z9) respectively.<\/p>\n

Pilot-Operated Check Valves<\/h3>\n

Load holding and flow blocking are ensured by the flanged valves of the series. The Z16 model is a pilot-operated check valve that acts simultaneously on both ports (A and B). For asymmetrical configurations, it is possible to install the Z15, which acts as a pilot-operated check valve exclusively on port A, or the Z24, operating on port B. It is essential to note that for the installation of the check valves (such as the Z16), the directional control valve body must be pre-arranged.<\/p>\n

Construction Features and Connections<\/h3>\n

All components are designed for direct mounting on the series’ directional control valves. The threaded connections for the pressure relief and anti-shock valves include various dimensional options to fit the different bodies, with threads available in M16x1.5, M18x1.5, and M22x1.5 sizes, ensuring optimal mechanical and hydraulic sealing under high-pressure conditions.<\/p>\n
