  • The body of regulator has inlet and outlet port. There are two springs one is light and other is main spring. The main spring can be compressed by spring adjusting screw. The diaphragm is attached to main spring.

  • The high pressure of the compressed air should be regulated to the requirement of the circuit. When main spring is compressed by adjusting the screw upward the diaphragm will move upward. This will lift the valve element upward, creating an opening to allow the air from inlet to outlet.

  • The opening of the valve and pressure flowing through it will be directly proportional to compression of the main spring.

  • When spring pressure is less the amount of opening will be small and there will be slight pressure reduction. If spring compression is more then there will be more pressure reduction hence regulator will work like pressure reducing valve.
