Types GAW and GVG
Class 9016 / Refer to Catalog 9012CT9701
Type GAW—Sensitive Control Applications
| |
9016GAW vacuum switches are provided with double throw contacts; normally open and normally closed circuits allow these controls to be used for standard or reverse action applications.
Standard devices can be mounted from the front with the bracket provided. Two mounting screws are required for a firm attachment to any smooth, flat surface. Allowance must be made for flange projection. Controls with Form F modification include two mounting feet with 9/32" mounting holes on 3-3/4" centers. Range and Differential adjustments are internal and exposed by removal of the front cover.
Maximum allowable positive pressure: 100 psig.
Diaphragms
are oil resistant, nitrile butadiene (Buna N) rubber.
