Basic technical data of cutoff valves with the discharge slide and the guide bush

Application

Cutoff valves type КО are stationary elements of automated control systems for technological processes and they are meant for installation on pipelines with the aim of providing two-position control (open and closed) of the working medium flow.

ü Рабочая среда: liquids and gases, which are not aggressive to the materials of the valve’s parts, which directly touch them.

ü Working medium temperature: from minus 60 °C up to plus 565 °C.

ü Port area: DN15, … , DN500.

ü Conventional pressure: PN6, … , PN250.

Characteristics

Straightway valves with the pneumatic (PM), electrical (EM) or manual (MM) executive mechanism (drive).

Rod seal – gland seal.

Connection to the pipeline – flanged. Connecting dimensions according to GOST 12815-80.

Types of executive mechanisms:

– pneumatic: pneumatic membrane-spring executive mechanism MEM1, pneumatic piston executive mechanism МИП or pneumatic drive PD;

– electrical: electrical forward trace executive mechanism.

Action type of the valves with the pneumatic drive: normally-open (NO) and normally-closed (NC).

The type of gasket in the closure:

– MM (metal on metal) – the leak-proofness in the closure is provided by conical surfaces with the built-up welding with wear-resistant material;

– ME (metal on elastomer) the leak-proofness in the closure is provided by flat surfaces with the application of fluoroplastic -4 as elastomer.

– MC (metal ceramic) – the leak-proofness in the closure is provided by conical surfaces with the built-up welding with metal ceramic materials.

– EE (elastomer on elastomer) – the leak-proofness in the closure is provided by the surfaces with the application of fluoroplastic -4 as elastomer.

– WC (wedge closure) – the leak-proofness in the closure is provided by the metal wedge piece and the seat, located on-the-miter to each other.

Leak-proofness grade: А or В according to GOST 9544-2005.

The sound level, created by the valves, doesn’t exceed 80 dB^·A.

By the customer’s order the valves can be supplied with the cooling (heating) jacket of the cutoff body.

A T T E N T I O N:

THE TYPE OF APPLIED ADDITIONAL UNITS IS AGREED BY ORDER.

The electrical devices (electric limit switches, EM and electro-pneumatic valves), applied in the valves, have explosion-protected performance.

Operating position of the valves – any, preferably vertical (executive mechanism up), the valves with DN200 and DN250 – only vertical (executive mechanism up).
