Product Overview
The Rexroth VAPRI.08A.20-A (Material No. 04118356200000 / R930008427) is a direct-operated proportional pressure relief valve designed for precise, infinitely variable pressure control in industrial hydraulic systems. As a key component within Rexroth’s proportional valve portfolio, this valve functions as a pilot-operated pressure limiting device where the command signal is proportional to the system pressure set point. It is engineered to provide smooth, stepless pressure adjustment in response to an electrical input signal, making it ideal for applications requiring dynamic pressure regulation, soft-start/stop sequences, and energy-efficient load holding. The VAPRI series is widely recognized for its fast response, low hysteresis, and excellent repeatability, ensuring stable operation even under varying flow and temperature conditions.
