The line blind valve consists of body 100, bonnet 139 and blind plate 368 which shuts
off fluid flow in body 100. The seating faces of body 100 and blind plate 368 are
hard-faced. Blind plate 368 rests against plate 198 in the body seat via fully threaded
stud 563 and nut 920.2.
The line blind valve is equipped with a pressure seal cover. The pressure inside the
