Principle of Operation

(Refer to Figure 1)

When the downstream pressure is greater than the set point of

the pilot, the pilot is closed, resulting in equal pressure above and

below the main diaphragm. With a balancing plug area slightly

larger than the seat area, the resulting closing force, along with

the force of the main spring, forces the plug against the seat.
With an increase in demand, the outlet pressure will begin to

drop and decrease the pressure above the main diaphragm. A

drop of outlet pressure below the pilot set point will cause the

pilot to open.
As the pilot opens, pressure increases underneath the main

diaphragm faster than pressure can bleed through the restrictor.

The imbalance in pressure on the main diaphragm overcomes

the spring force and the additional closing force from the

balanced plug, causing the plug to rise off the seat and satisfy

the flow demand.
Once the flow demand is satisfied and the downstream pressure

begins to increase, the pressure above the main diaphragm and

in the pilot sense cavity rises. This causes the pilot to close. The

pressure below the main diaphragm bleeds through the restrictor

until pressure equalizes above and below the main diaphragm.

The forces of the main spring and the balanced plug then close

the plug on the seat.
