Beschreibung
Zusammenfassung:	The present invention provides more efficient, cost effective coke drum isolation valve devices and system as well as more efficient, cost effective methods for isolating the flow of matter from location to another in the delayed coker unit operation where the valve comprises a first seat; a second seat aligned with said first seat; a blind; a main body having an orifice dimensioned to align with an orifice in said line; wherein said main body is coupled to said line; an upper and lower bonnet coupled to said main body, wherein said bonnets may be removed in order to replace valve parts without separating the main body from the line; and a plate located inside a bonnet, wherein the plate comprises a planar surface that contacts a surface of the blind.
