Pressure controllers

Pressure controller RDU-80 (РДУ-80)

Gas pressure controller is used for reducing and automatic keeping of gas pressure in downstream direction at the set point. Pressure controllers are used on main pipelines facilities – gas compressor stations and gas distribution stations.

Pressure controller (air reducer) VM.RV-1 (ВМ.РВ-1)

Pressure controller without gas consumption is used as setting device for gas pressure controllers and automatic keeping of controller’s output pressure. Pressure controllers are used on the pipe lines facilities – gas compressor stations and gas distribution stations, etc. It consists of two controllers that provide two control steps, actuation of each step safety- relief device can be adjust within wide range.
