Overpressure Protection Options:

Slam-Shut Protection
Secondary Seat™ Protection - Provides a
solution to the most common cause of regulators
failing to shutoff by employing a secondary
seating surface for shutoff if the primary orifi ce
seating surface becomes damaged or blocked.
Internal Relief - Minimizes downstream pressure
buildup by relieving gas through the diaphragm
assembly and out the 1 NPT vent to atmosphere
in the event of an overpressure situation.
High Capacity Relief - Large 2-1/2 NPT vent
provides a signifi cant increase in relieving
capacity and level of overpressure protection to
the downstream system.
Integral True-Monitor™ Protection - Combines
the operation of a conventional two-regulator
wide-open monitor set into one device without
the need for a downstream control line.
Slam-Shut Protection - Provides an integral
slam-shut module that shuts off the fl ow of gas
to the downstream system in an overpressure or
underpressure situation.
