Gas pressure regulator РЕД-7-1,6
Pressure regulators РЕД-7 are designed to reduce high and medium pressure to high, medium and low pressure.
The pressure regulators have a axial-flow design, which, depending on the version, may include the following devices: built in SSD, regulator-monitor and active silencer.
Available versions:
- Regulator
- Regulator + Monitor
- Regulator + SSD
- Regulator + SSD + Monitor
- All versions + silencer
РЕД-7 can be manufactured in both versions: FC (standard) and FO (custom) version.
