Air pressure valve

Products Mode: NV-5039
Air vent valve
Size: 1/2" 3/4"

An air pressure valve controls the air pressure in whatever the air is flowing through. When the pressure is increased, the diaphragm will roll opposite of the springs. When the air pressure is more than the springs can handle, the diaphragm takes charge over the springs. When pressure is regulated, the valve will open gradually and the springs will push the main shaft down once again.
