Specifications

Available Constructions

Type 133H: High pressure construction for outlet

pressure range of 1-1/2 to 10 psig (0,10 to 0,69 bar).
The Type 133H can also use the 5 mbar to 0,14 bar
(2-inches w.c. to 2 psig) springs of the Type 133L.
The maximum operating inlet pressure is 4,1 bar
(60 psig) with a maximum emergency inlet
pressure of 8,6 bar (125 psig).

Type 133HP: Extra high pressure construction for
outlet pressure range of 0,14 to 4,1 bar (20 to 60
psig). The maximum operating inlet pressure rating
of 10 bar (150 psig) with a maximum emergency
inlet pressure of 10 bar (150 psig).

Type 133L: Low pressure construction for outlet
pressure range of 5 mbar to 0,14 bar (2-inches w.c.
to 2 psig). The maximum operating inlet pressure is
4,1 bar (60 psig) with a maximum emergency let
pressure of 8,6 bar (125 psig).

Type 133Z: Zero gravity governor construction for
outlet pressure range of -2,5 to 10 mbar (-1 to 4­inches w.c.). The maximum operating inlet pressure
is 1,4 bar (20 psig) with a maximum emergency
inlet pressure of 8,6 bar (125 psig).

Installation

Only qualified personnel should install or service
a regulator. Regulators should be installed,
operated, and maintained in accordance with
international and applicable codes and
regulations, and Fisher instructions.

If the regulator vents fluid or a leak develops in
the system, it indicates that service is required.
Failure to take the regulator out of service
immediately may create a hazardous condition.

Personal injury, equipment damage, or leakage due
to escaping fluid or bursting of pressure-containing
parts may result if this regulator is overpressured
or is installed where service conditions could
exceed the limits given in the Specifications section,
or where conditions exceed any ratings of the
adjacent piping or piping connections.

To avoid such injury or damage, provide pressure­relieving or pressure-limiting devices (as required
by the appropriate code, regulation, or standard) to
prevent service conditions from exceeding limits.

Additionally, physical damage to the regulator could
result in personal injury and property damage due
to escaping fluid. To avoid such injury and damage,
install the regulator in a safe location.

Clean out all pipelines before installation of the regulator
and check to be sure the regulator has not been damaged
or has collected foreign material during shipping. For NPT
bodies, apply pipe compound to the male pipe threads. For
flanged bodies, use suitable line gaskets and approved
piping and bolting practices. Install the regulator in any
position desired, unless otherwise specified, but be sure
flow through the body is in the direction indicated by the
arrow on the body.

Note

It is important that the regulator be installed so that
the vent hole in the spring case is unobstructed at all
times. For outdoor installations, the regulator should
be located away from vehicular traffic and positioned
so that water, ice, and other foreign materials cannot

enter the spring case through the vent. Avoid placing
the regulator beneath eaves or downspouts, and be
sure it is above the probable snow level.

Overpressure Protection

The recommended pressure limitations are stamped on
the regulator nameplate. Some type of overpressure
protection is needed if the actual inlet pressure exceeds the
maximum operating outlet pressure rating. Overpressure
protection should also be provided if the regulator inlet
pressure is greater than the safe working pressure of the
downstream equipment.

Regulator operation below the maximum pressure limitations
does not preclude the possibility of damage from external
sources or debris in the line. The regulator should be inspected
for damage after any overpressure condition.

Startup

If the downstream system is already pressured
by another regulator or by a manual bypass, then
extra precautions must be taken when placing
the 133 Series in service. The outlet of the regu­lator must never be subjected to pressures higher
than the inlet pressure, or the balancing dia­phragm may be damaged. Also, the control line
pressure must never exceed the set point dic­tated by the spring setting by more than 0,21 bar
(3 psig), or the valve seat or diaphragm plates
can be damaged.

The regulator is factory set at approximately the midpoint of
the spring range or the pressure requested, so an initial
adjustment may be required to give the desired results. With
proper installation completed and relief valves properly
adjusted, slowly open the upstream and downstream shutoff
valves.

Adjustment

To change the outlet pressure, remove the closing cap or
loosen the locknut and turn the adjusting screw clockwise
to increase outlet pressure or counterclockwise to decrease
pressure. Monitor the outlet pressure with a test gauge
during the adjustment. Replace the closing cap or tighten
the locknut to maintain the desired setting.

Taking Out of Service (Shutdown)

To avoid personal injury resulting from sudden
release of pressure, isolate the regulator from all
pressure before attempting disassembly.
