A valve has a housing and a component movable within the housing. The housing has first, second and third ports formed in it. The movable component has a first passageway formed in it. Movement of the movable component within the housing selectively connects the first port through the first passageway to the second port, or the second port through the first passageway to the third port. At least one of the first and second ports includes a first member for contacting the movable valve component and a second member for retaining the first member. The second member may be constructed from a semiconductive material. At least a region of the movable component around a first end of the first passageway may be semiconductive.
A valve having a housing and a component movable within the housing, the housing having first, second and third ports formed in it, the movable component having a first passageway formed in it, movement of the movable component within the housing selectively connecting the first port through the first passageway to the second port, the movable component being selectively movable to disconnect the first port and second port and to connect the second port through the first passageway to the third port, a first end of the first passageway terminating adjacent an outer surface of the movable component within a first relief, and a first member for insertion in the first relief, the first member being constructed at least partly from semiconductive material and including a passageway therethrough providing communication between the first end of the first passageway and the outer surface of the movable component.
