Valves: KMR (regulating valves), КМО (shut-off valves), КМRО (control and shut-off valves) are intended for controlling the working medium flow/pressure in the pipeline or blanking the flow. They are used for both neutral and chemically aggressive media. The throttling unit is mainly of plunger type and it can have both balanced and unbalanced structure, which is determined by the nominal diameter and the required differential pressure. Valves are produced based on a cast or forged body. They can be equipped with manual, pneumatic or electric drives.
