Control valves VOLGOGRADNEFTEMAS KRD 65235, CRO 65501, etc.

The two-seat control valves of the KRD series are designed for use in systems of automatic regulation and control of technological processes of chemical and other industries for the purpose of continuous regulation of the parameters of the working medium (flow, pressure), manufactured with pneumatic diaphragm spring actuators (MIM) or with electric actuators (EIM). The valves are manufactured in climatic versions U, XL, T according to GOST 15150.

Ambient temperature:

• -for climatic performance in (areas with a temperate climate) from minus 40C to plus 50C;
• -for climatic performance of HL (areas with a cold climate) from minus 60C to plus 45C;
• -for the climatic version of T (areas with a tropical climate) from minus 10C to plus 50C.

Ambient humidity from 30% to 80%.

Nominal diameters: DN 25, DN 40, DN 50, DN 80, DN 100, DN 150, DN 200, DN 250.

Single-seat control valves of the KRO series are designed for use in process control systems at oil and gas facilities, chemical industry and other industries in order to automatically regulate various parameters. Type of climatic design of valves - U and XL, type of atmosphere - II (industrial) according to GOST 15150:

• -for the execution of U1 from minus 400 S to +500 S (steel 20L, 12X18N9TL and 20GML for the manufacture of the housing, lid);
• -for the execution of HL1 from minus 600C to +450C (steel 12X18N9TL and 20GML for the manufacture of the housing, lid).

They are made in the following versions:

• with pneumatic diaphragm actuating mechanism (MIM);
• with manual drive (RP);
• with an electric actuating mechanism (EIM).

Nominal diameters: DN 25, DN 40, DN 50, DN 80, DN 100, DN 150, DN 200, DN 250, DN 300, DN 400.
