Methods of Factory Sealing
EFS/EDS Series
Factory sealed EDS and EFS pilot light, pushbutton and selector
switch control stations do not need external sealing. Device contacts
are factory sealed in explosionproof ESWP contact blocks. Small,
compact enclosures have accurately ground wide flanges on both
the body and cover for a flame-tight joint.
EDS Series
EDS factory sealed snap switches or manual motor starting switches
do not need external sealing. The switches are enclosed in a unique
sealing well with double flanges which mate with the cover and the
body. Small, compact enclosures have accurately ground wide
flanges on body, cover and sealing well for flame-tight joints. Wiring
pigtails are factory sealed from under the sealing well. Reliable
pouring of seals at the factory ensures safe sealing.
