PEECO Explosion-Proof
Flow Switches
|
| For Hazardous Locations with Maximum Allowable Pressure to 600 PSI |
|
 Flow Actuated Electrical Switches are unique in the field of flow controls. Our switches are not a standard shelf item, but are specifically produced to accommodate your application. The flow switches are maintenance free in lines from 1/16" to 12' or larger.
All explosion proof models are rugged, heavy duty units exceeding all UL Code requirements. Each of the four basic styles are adaptable to many other fittings and configurations. Utilizing 1/4" thick Heat treated aluminum cover (shown at right) with 5 fully engaged threads, these units are designed to encapsulate any internal explosion. All explosion proof models meet Class 1, Group D requirements for use in hazardous locations; all NEMA classifications available. The housing & cover are both made of heat treated aluminum T-356 and are epoxy coated (for extra protection). Other classes and groups are available. Conduit outlet: 1/2" NPT on all models; 3/4" and metric sizing available. |
