Installation
!
WARNING
Only qualified personnel should install
or service a valve. Valves should be
installed, operated and maintained
in accordance with international and
applicable codes and regulations, and
Emerson Process Management Regulator
Technologies Inc. instructions.
If the valve vents fluid or a leak develops
in the system, it indicates that service
is required. Failure to take the valve 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 valve 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.
1. The pressure/temperature limits in this Installation Guide, ASCO solenoid documentation and any applicable standard or code limitation should not be exceeded.
2. Pressure and/or the body end connection may decrease these maximum temperatures.
3. Not for use with hot water or Ammonia (NH3).
4. Minimum temperature for cast iron body is -29°C / -20°F.

119 Series
2
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
valve could result in personal injury and
property damage due to escaping fluid.
To avoid such injury and damage, install
the valve in a safe location.
Clean out all pipelines before installation of the valve
and check to be sure the valve has not been damaged
or has collected foreign material during shipping. For
NPT bodies, apply pipe compound to the external pipe
threads. For flanged bodies, use suitable line gaskets
and approved piping and bolting practices. Install
the valve 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 valve be installed
so that the vent hole in the spring case
is unobstructed at all times. For outdoor
installations, the valve 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 valve beneath eaves or downspouts
and be sure it is above the probable
snow level.
Overpressure Protection
The recommended pressure limitations are stamped
on the valve 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 valve inlet pressure is greater than the
safe working pressure of the downstream equipment.
Valve operation below the maximum pressure
limitations does not preclude the possibility of
damage from external sources or debris in the line.
The valve should be inspected for damage after any
overpressure condition.
Startup
The valve 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 control pressure, remove the closing
cap or loosen the locknut and turn the adjusting
screw clockwise to increase control pressure or
counterclockwise to decrease pressure. Monitor
the control 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)
!
WARNING
To avoid personal injury resulting from
sudden release of pressure, isolate
the valve from all pressure before
attempting disassembly.
