capacities in a wide variety of distribution, industrial
and commercial applications. A 299H Series regulator

Figure 1. 299H Series Pressure Reducing Regulator
The integral token relief on the Types 299HR and
299HSR regulators is located in the pilot and opens
to relieve minor overpressure.
The Type 299HS provides overpressure or overpressure
and underpressure protection by completely shutting off
the ow of gas to the downstream system. It comes with
a Type VSX-2 slam-shut device which can be congured
for Ovepressure Shutoff (OPSO) or Overpressure and
Underpressure Shutoff (OPSO/UPSO). The slam-shut
device’s actions are independent of the main valve and
of variations to the inlet pressure. The Type VSX-2
slam-shut device has internal or external registration.
External registration requires a downstream sensing line.
