Compact Proportional Pressure Regulator (0-7bar)

QKL-B1N

Compact Proportional Pressure Regulator (0-7bar)

QKL-B1N inherits the high performance and stability of the QKL-B1T proportional valve series, but has been greatly improved in structural design. The body size of this series has been reduced to half of the original, making it lighter, easier to integrate into equipment, and significantly enhancing installation flexibility. It is especially suitable for applications with limited space, high-density layout requirements, or modular equipment configurations. While retaining the closed-loop control architecture and dual-solenoid regulation mechanism, QKL-B1N continues to provide precise, fast, and stable pressure control. Both input signals and monitor signals offer options of 0–10VDC (voltage), 4–20mA (current), and RS485 ModBus.
