Product Overview
The Plasser & Theurer H40FOFM4NAH / EL-T 76.00-MO-191C is a high-performance hydraulic solenoid directional control valve engineered specifically for the demanding hydraulic circuits of Plasser & Theurer track maintenance machinery. This 4-way, 3-position (4/3) directional control valve utilizes a precision-machined spool and a robust AC/DC solenoid actuator to direct hydraulic fluid flow, extend, retract, or hold actuators in position within the machine’s workhead, tamping, and lifting circuits. As a direct OEM-specified component, it ensures exact functional interchangeability with the original valve, maintaining the precise timing, pressure integrity, and leak-free operation required for railway track stabilization and tamping operations.
