Panel Mount Option Captured Vent Option (1/8" NPT)
option DeFinition
Captured Vent
The captured vent design is for maximum safety for the user when handling toxic or hazardous media. It features a
1/8" FNPT port located on the spring housing. The user can easily tube this vent to a safe location. This option can be
incorporated into a self-relieving regulator that provides an additional port to permit the safe expulsion of hazardous
media.
Panel Mount
The panel mount feature requires a panel cut out of 1-1/2", complete with a threaded spring housing, and a panel
mount ring to secure the regulator.
*Self Relieving
The self relieving option is used for internal venting of downstream pressure. From a practical stand-
point, it allows for immediate reduction in pressure setpoints and automatically alleviates regulator lock up.
