Ball Valves

TU 3763-013-49652808-2007

Ball valve is designed as check or control device to be installed on pipelines with flow media temperature not exceeding +120°C.

Composition of produced fluids: technical water, oil with СО₂ and H₂S up to 6 %; natural gas containing liquid hydrocarbons, ethyleneglycol, methanol (СН₃ОН), turbine oils, water and mechanical particles.

Resistance to the impact of the well media — K1, K2 in accordance with GOST 13846-89.

Operational temperature limits +40°C —60°C. Climatic category of the wellhead equipment — UHL(HL1) in accordance with the national standard GOST 15150-69.

Product specification level UTT-1(PSL-1) in accordance with the national standard GOST R 51365-99.

There are 2 types of the ball valves:

„T”-KSh (KShm) — full bore;
„T”-KShd — ball valves with built-in the gate chokes (quick-change or permanent, single or multi) for step control of the flow.

Ball valves are not intended for slide control of the flow.
