Model DL

Description

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.

Inlet Design Pressure

• Up to 300 psig (20.7 Barg)

Outlet Pressure

• Standard: 2-150 psig (0.14 - 10.3 Barg); in four range springs

Line Sizes

• 1-1/2" (DN40)
• 2" (DN50)

See the Model D for smaller sizes.

End Connections

Features

• Versatile: Five body materials and twenty six trim ma te ri al com bi na tions to se lect from.
• Tight Shutoff: Composition seats of TFE, Buna-N (NBR), FKM 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 overpressurization, diaphragm over-travel is restricted by mechanical stops.
