Key Features for Industrial Applications
Remote Variable Pressure Control
The standout feature of the EPCG2-03-210-N-11 is its ability to change system pressure on the fly via an electronic controller. This eliminates the need for manual valve adjustments and allows for automated «multi-stage» pressure cycles. This is particularly beneficial in applications where different phases of a machine cycle require different force levels, enhancing both efficiency and part quality.
Superior Linearity and Hysteresis
Tokio Keiki has optimized the 11-series design to ensure a highly linear relationship between the input current and the output pressure. With low hysteresis and excellent repeatability, this valve provides the consistent performance necessary for high-precision manufacturing, ensuring that every cycle performs exactly like the last.
