Ball valves

The ball valve is intended for use as a shut-off and (or) shut-off-regulating (discrete) device on pipelines with a temperature of the transported medium no more than plus 110 ° C.

Transported medium: technical water; oil with a volumetric content of CO2 and H2S up to 6%; natural gas containing liquid hydrocarbons, ethylene glycol, methanol (CHZON), turbine oils, water and mechanical entrained solids.

Corrosion-resistant version of valves – К1, К2 in accordance with GOST 13846 -89.

Limiting values ​​of ambient air temperature during operation: from -60 ° С to + 40 ° С.

Type of climatic modification UHL (HL) according to GOST 15150-69.

The level of technical requirements is according to GOST R 51365-99 UTT-2 (RSL-2).

Cranes are manufactured in two types:

“T” -KSH (KSHm) full bore

“T” -KShd – ball valves with integrated in the ball valve fittings (quick-change or non-changeable single (or multi-choke) for step regulation of the medium flow rate.

The valves are not designed for smooth regulation of the medium flow rate.
