DN15-DN32 Marine Bronze Air Reducing Valve 
DN15-DN32 Marine Bronze Air Reducing Valve
Marine  Air Reducing Valve
The reducing valve is a regulating device which serves to reduce the air pressure supply to the required delivery pressure
This particular design is constructed in two main sections; the upper portion which consists of a combined inlet and exhaust valve assembly and the lower portion which houses a diaphragm, the diaphragm spring and the spring adjuster.

With the valve in the inoperative position the upper (inlet) ball is held off its seat by the effort of the diaphragm control spring upon the lower (exhaust) ball seat, which in turn closes the exhaust valve.When air is applied to the supply connection it flows past the inlet ball valve to the chamber surrounding the valve unit and thence to the delivery line. At the same time supply pressure is felt on top of the diaphragm.

As the pressure increases so the diaphragm moves downwards, allowing the inlet spring to close the inlet ball valve, when balance is achieved between diaphragm spring force and delivery air pressure. Should the supply air pressure increase above that called for by the valve setting, the diaphragm will be forced downwards against the control spring, taking with it the exhaust valve seat. Thus the excess supply pressure is vented to atmosphere through the slot in the control spring casing.

If the delivery line pressure decreases the control spring will overcome the force of the air pressure on top of the diaphragm and the diaphragm plus exhaust seat will move upwards. This results in the inlet ball valve being unseated and further air supply can flow to delivery thus restoring the pressure to the desired value.
