Disk Gate Valve

TU 3741-001-49652808-2000

Disk gate valves are designed to stop the flow in pipelines with different pressure and nominal bores. Flow media — water, technical oil, oil emulsion. Total service life is not less than 15 years. Time to failure is not less than 600 cycles. Total average life until the first full repair is not less than 5 years. Opening or closing operation is performed by the handle stop-to-stop position (90°).

Climatic category of the wellhead equipment — UHL(HL1) in accordance with the national standard GOST 15150-69.

Operational temperature limits +40°C −60°C. Flow media temperature is not exceeding +120°C.

Direction of the flow — any.

Typical sizes of the disk gate valve flanges are in accordance with GOST 12815.
