Ball Valves       

     "A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it." The ball valve is used in the pipeline to cut, distribute and change the flow direction of the medium.

Ball valves have the advantages of small torque value, smooth channel, good sealing performance and easy operation. It is easy to realize automatic control and remote control. DONAU ball valve can adapt to different actuators, including pneumatic actuator, hydraulic actuator and electric actuator.

Ball valves could be divided into forged steel ball valve, cast steel ball valve, including fully welded ball valve, metal seated ball valve, cryogenic ball valve, three-way ball valve, multi way ball valve, top entry ball valve, trunnion mounted ball valve, floating ball valve, etc.

According to different requirements, DONAU ball valves size ranks from 1/2" to 60", DONAU ball valves pressure ranks from CLASS 150 to CLASS 2500,

They are all implemented according to the design standards of the API6D and API608.

Donau ball valves can be used in various working conditions such as urban gas, central heating, heat exchanger, steel plant, hydropower station, metallurgy, offshore platform, food and medicine, water and sewage treatment, petrochemical industry, gas, natural gas, liquefied petroleum gas, cryogenic condition, etc.
