Our latest developed RFBMA46F KPa level ultra-low pressure diaphragm pilot safety valve is mainly used to protect atmospheric storage tanks, low-pressure storage tanks, and low-pressure pipeline systems. It can release pressure normally and reliably under the set pressure of KPa level, and achieve reliable sealing with zero leakage after reseating and closing. This structural safety valve solves the problem of difficult implementation of commonly used safety valves in the ultra-low pressure range, and will have good application prospects in atmospheric and low-pressure storage tank systems.
Guide valve operation, providing reliable sealing force to the main valve until the set pressure, preventing forward leakage and reducing energy consumption;
Both the main valve and the pilot valve are equipped with highly sensitive diaphragms, which provide sensitive opening, disourphpging, and reseating actions, high precision, and good stability;
The valve seat adopts soft sealing, and the valve seat and diaphragm materials are widely ourphped, suitable for different working conditions and media;
By simple adjustment, it is possible to achieve sudden opening or proportional opening, with obvious effect, large release capacity, and the ability to restore bubble level sealing after release;
Can achieve ultra-low voltage setting: 8KPaG-25KPaG (0.08barG-2.5barG);
