Product Overview
The Rexroth VESP-08A-12A-00-2T32-N7 (Material No. R934004903 / OD1532181DS20C) is a high-performance solenoid-actuated directional spool valve engineered for precise control of start, stop, and direction of hydraulic fluid flow in industrial systems. Featuring a robust 4-way, 3-position (4/3) spool configuration with spring-centered return and dual wet-pin AC/DC solenoids, this valve provides reliable, fast switching and leak-free load holding. Its high-strength cast iron housing and hardened, precision-ground spool ensure minimal internal leakage, excellent hysteresis characteristics, and long service life even under continuous duty cycles. Designed as a direct fit replacement for original Rexroth components, the VESP-08A series is ideal for demanding applications requiring accurate directional control, smooth deceleration, and high cycle rates.
