The Bosch Rexroth 4WRVE10V85L-2X/G24ETK0/B5WG02M (R901168841) is a sophisticated, pilot-operated high-response directional valve designed for servo applications requiring precise control and responsiveness. This valve features integrated electronics OBE with a position controller for both the pilot and main stage, ensuring highly accurate operation. The main stage of the valve boasts servo quality with position feedback, which contributes to its exceptional performance in dynamic applications. With its advanced design, the 4WRVE10V85L-2X/G24ETK0/B5WG02M offers various flow characteristics such as progressive and fine control edges (M), inflected characteristic curves (P), and a linear flow pattern (L). These characteristics allow for tailored responses to match specific application requirements. The valve is calibrated in the plant, ensuring it meets stringent quality standards right out of the box. This model's size and component series X indicate its compatibility with a range of hydraulic systems. It can withstand a maximum operating pressure of up to several hundred bar while providing maximum flow rates that are suitable for most industrial applications. The nominal flow rate is also specified in liters per minute, which facilitates precise system design and ensures efficient operation within its intended range. Overall, the Bosch Rexroth 4WRVE10V85L-2X/G24ETK0/B5WG02M is engineered to deliver high-performance and reliable control for complex hydraulic systems requiring exacting precision and fast response times.
Valves of type 4WRVE are pilot-operated high-response valves in servo quality.

NG27 is a high-flow version of NG25, the connection bores P, A, B, T in the main stage are designed with Ø32 mm. Deviating from the standard ISO 4401-08-08-0-05, ports P, A, B, T can be bored in the manifold with a maximum of Ø30 mm. So these valves offer higher flow values QA : QB |
