MODEL DL
PRESSURE REDUCING REGULATOR
BODY SIZES 1-1/2" & 2"(DN40 & 50)
Model DL is a redesignation of the former Model D
product, limited to 1-1/2" & 2" (DN40 & 50) body sizes.
The Model DL is a basic, general service, self-contained regulator. Unit handles inlet pressure of up to 300
psig (20.7 Barg) and outlet pressures from 2-150 psig
(.14-10.3 Barg) in multiple spring ranges. Model DL is the
Cashco reducing regulator product utilized for the majority
of industrial applications. A time-proven product with 80+
years of experience.
FEATURES
MODEL DL
APPLICATIONS
Used in all types of fluids, including sour gas, industrial
gases, chemicals, as well as the common industrial fluids
- water, oil, steam and compressed air.
Versatile:
Five body materials and twenty trim
material combinations to select from.
Tight Shutoff:
Composition seats of TFE, Buna-N
(NBR) or EPDM available.
Capacity:
Handles mid-range flow rates on a
line size basis.
Pressure Drop:
Handles mid-range pressure drops
while maintaining good stability.
Flow-to-Close
Plug:
Incorporates the typical reducing
regulator internal design.
Incorporated
Cylinder:
Plug is guided through its travel by the
cylinder, which also serves to block
harmful debris from entry to the seating surfaces.
Overpressure
Travel Stop:
In the event of downstream over-pressurization, diaphragm over-travel is
restricted by mechanical stops.

NOTE 1: Trim Designation Nos. in "boldface" are the most commonly used. Cashco, or its representatives may
make recommendations or suggestions as to the suitability of certain trims for specific services. These
are trims that have been used successfully in the past in similar applications. However, the user has final
responsibility for materials selected.
NOTE 2: Cashco, Inc. does not recommend metal seated trim on any service where the flow will be dead ended
down stream of the pressure reducing regulator.
In accordance with ASME B31.3 “process piping”, do not use Cast Iron Body for hydrocarbon or flammable fluid
service with inlet pressures greater than150 psig (10.3 Barg) or temperatures greater than 300° F (149° C).
* NACE Trims for use w/ LCC Body Material Temperature Range -50 to +250°F (-46 to +121°C).
