Type HSR regulators provide internal relief that limits the
total outlet pressure buildup over setpoint. This internal relief
may be adequate for the application, if not, provide additional
pressure relief or a pressure-limiting device downstream.
Regulators should be inspected for damage after any
overpressure condition.
!
WaRnIng
To avoid personal injury or property damage
due to explosion or damage to regulator or
downstream components during startup,
release downstream pressure to prevent an
overpressure condition on the diaphragm of
the regulator.
In order to avoid an overpressure condition
and possible equipment damage, pressure
gauges should always be used to monitor
pressures during startup.
Startup
With proper installation completed, slowly open the
shutoff valve. Check all connections for leaks. Check the
downstream equipment for proper operations.
adjustment
To increase the outlet pressure setting, turn the adjusting
screw clockwise. To reduce the outlet pressure setting, turn
the adjusting screw counterclockwise. A pressure gauge
should always be used to monitor downstream pressure
while adjustments are being made. Do not adjust the spring
to produce an outlet pressure setting above the limit identified
on the information label. If the required pressure setting is
not within the range of the spring being used, substitute with
the correct spring. When changing the spring, also change
the range identified on the information label to indicate the
actual pressure range of the spring in use. After the spring
adjustment has been completed, replace the closing cap.
