It is used for the regulation and automatic keeping of the set working pressure of carbon dioxide as a constant one during foodstuff saturation.
|
|
Since the beginning of 2014 pressure regulators URP-DM have been produced with modernized reducing and safety valves.
URP-4-2DM (8) * (with a valve)
SKU 030.000.03
|
|
|
The pressure regulator with new reducing and safety valves differs:
- less increasing of pressure while gas feeding termination (exact control)
- less changing of working pressure while inlet pressure decreasing
- stability of the safety valve operation.

Donmet regulators have improved reducing valve
|
Since the beginning of the 2014 carbon dioxide and argon regulators: АR-40/U-30-2DМ, АR-40/U-30-4DМ, АR-40-4DМ and UR-6-4DМ are produced with improved reducing unit.
|
|
| АR-40/У-30-4DM |
АR-40-4DM |
UR-6-4DM |
АR-40/U30-2DM (with flowmeter) |
|
Regulators with new improved reducing unit have the following characteristics:
• increased resistance and reliability (probability of failure is less than 0,01%)
• increased accuracy of keeping set pressure or consumption (welding without defects)
• low pressure increase while stopping gas feeding (saving 10-20% of protective gas), while welding with discontinuous seam
• durability (always ready to work)
|
| Reducing unit of large-size carbon dioxide and argon regulators has been produced since 2014. |
