Internal pilot-operated pressure reducing valve
The PJXN pressure reducing valve primarily controls the main valve pressure by adjusting the gas pressure of the pilot valve. It is an internally-piloted pressure reducing valve, where a small pressure reducing valve controls a larger one. Compared to direct-acting pressure reducing valves, it requires less effort to adjust and exhibits smaller fluctuations in output pressure. Consequently, it is widely used in control systems that handle large flow rates and high pressures.
