The job of the progressive starter is to feed air into the circuit gradually with

controlled flow. It comes in two versions with solenoid or pneumatic actuation.

Both control signals cause the valve to open, which allows the air controlled

by the flow regulator to flow slowly towards the downstream circuit.

In the APR, when the pressure in the downstream circuit reaches 50%-60%

of the upstream pressure, the valve opens the main inlet duct connecting.

The time elapsing between starting and opening the valve can be adjusted via

the built-in flow regulator. If it is necessary to relieve the downstream circuit

quickly, merely operate the control valve which cuts off air flow in the pipe.

This closes the valve and starts relieving the downstream circuit.

The progressive starter acts both as an actuator positioner, which eliminates

the risk of sudden kickback, and as a valve.

N.B.

With size 400, when the APR is mounted upstream of the regulator,

the pilot regulator must be piloted at a pressure taken upstream of the APR,

otherwise when the system is relieved, most of the air downstream will be

relieved by the regulator and not the APR relief port.

In any position

Filtered, lubricated or unlubricated compressed air. Lubrication, if used, must be continuous.

For the pneumatic version 200 the pilot pressure must range between the inlet P and the inlet P + 2 bar.

For pneumatic version 300, the pilot pressure must be greater or equal to the input pressure.
