Where is the zero pressure valve used?
It is suitable for the gas flow control regulator of all combustion systems, and is used together with proportional mixer, internal mixing burner, positive and negative furnace pressure, etc. The patented compensator automatically adjusts the position of the valve to maintain the outlet pressure at any flow rate. The first pressure change measured by zero pressure valve has nothing to do with the flow rate of pipeline gas; Then, the zero pressure valve controls the second measured air pressure by adopting the design of diaphragm type and internal automatic biasing reverse spring. The second measured air pressure can be equal to the ambient air pressure where the equipment is located through the ambient air pressure inlet and pressure regulating valve, and it can also be negative pressure (ambient air pressure is higher than the air pressure in the equipment) or positive pressure (the air pressure in the equipment is higher than the ambient air pressure).
