Product Overview
The DANFOSS PVBS 157B7102 is a precision-engineered proportional valve spool designed for use within Danfoss PVBS series proportional directional control valves. As a critical metering component, this spool governs the direction and magnitude of hydraulic fluid flow in direct proportion to an electrical input signal, enabling smooth, infinitely variable control of actuator speed and position. Manufactured by Danfoss, a global leader in mobile and industrial hydraulics, the 157B7102 spool is machined to exacting tolerances to deliver precise flow metering, minimal hysteresis, and consistent performance across the full operating envelope. It serves as a direct replacement component for PVBS proportional valve platforms used in demanding motion-control systems.
