Instruction Manual DSV1000 Valve June 2022 D104727X012 WARNING When lifting the ball, ensure the bearing plates (key 11) are secure on the ball trunnions to prevent parts from falling which may cause personal injury or property damage. Note Refer to figure 6 and note the NPS6 CL150 construction is different than the balance of the DSV1000 product line in that it lacks bearing plates and the ball design does not have male trunnions. - Page 11 Instruction Manual DSV1000 Valve D104727X012 June 2022 5. Lubricate and install the O‐rings (key 13) in both tailpieces. a. For NPS 6 through NPS 12 constructions, one O-ring per tailpiece is required. b.
