Technical Description
In the series PILOT WA 900 is a simple modular system that permits all practical
service combinations. There are two basic models, one with and one without
internal control. There are two different quick-change adapter plates that are
suitable for both models and can be retooled for recirculation systems.
The guns of WA 900 series can only be used in conjunction with an adapter plate.
You can either use the standard or low-profile adapter plates. To integrate the guns
in a recirculation system the built-in locking pin must be removed (item 37).
The PILOT WA 900-series models operate automatically via a compressed air
control and are controlled via a 3/2-way solenoid valve.
