Product Description

Delayed Coking Ball Valve product description

Delayed Coking Ball valves(Generally flanged connection, but Butt-welding optional) are suitable for using on various kinds of pipeline from Class150 To Class1500, PN16 To PN100 to cut off or connect the flowing of medium. By using different material, the valves could be suitable for medium such as water, steam, oil, nitric acid, acetic acid, oxidizing substance, carbamide and etc. Manual/worm gear/pneumatic or electric actuators could be chosen by needs. 

Flanged Delayed Coking Ball Valve

At present, high temperature ball valve is widely used for domestic delayed coking device, both for the tower botten's residual oil pipe or tower top's oil gas pipe.  The high temperature ball valve used in big oil refineries in our country at this moment are imported, and needed to be overhauled after many years' working.  During the maintenance and overhaul of these valves, the high temperatures used for delay coking device has a not very complex structure and quite reasonable material using and manufacturing  technique.

With integrally casted ball & stem, Delayed Coking Ball valve realizes its controlling of cutting off or connecting the flowing of medium by the rotation function of actuator.  As the medium is residue oil or coking oil gas, steam is used to blow the internal surface of delayed coking ball valve to avoid the phenomenon of coking in valve. And the pressure of blowing steam is about 0.8~1.0MPa with temperature of 250~280ºC.
