Chemically-resistant fluid control valves |
摘要 |
A chemically-resistant fluid control valve is disclosed generally comprising fluid inlet and outlet passages separated by fluid control means, which control means comprise a flapper plate disposed in the fluid passageway and mounted on a rotatable shaft that passes laterally through the fluid passageway by means of releasable fasteners adapted to engage correspondingly-shaped fastener elements of the flapper plate, which elements are also adapted to receive the shaft in a channel between the fastener elements, wherein at least all wetted surfaces of each of the several components consist essentially of a chemically-resistant material.
