RZME-A, CART RZME-A
The Atos RZME-A and CART RZME-A are high-precision, direct-acting proportional pressure relief valves designed to control hydraulic pressure in direct proportion to an input electrical signal. They operate as open-loop components, meaning they rely on a steady electrical current from an external driver rather than built-in electronic feedback to manage system pressure.
- Operating Pressure : High Performance Range
- Application : Industrial & Mobile Systems
About this item
The Atos RZME-A and Atos CART RZME-A are poppet-type, direct-acting proportional pressure relief valves designed for open-loop pressure control systems. Manufactured by the Atos Group, these components do not include an integrated transducer (“-A” designation) and must operate alongside an off-board electronic driver. The driver provides the precise electrical current required to balance hydraulic pressure against the input reference signal.
