A valve assembly includes a valve body. The valve body includes a valve seat. The valve seat defines a bore therethrough. The valve body also includes a pair of end members connected to the valve body at opposing sides of the valve body. Each of the pair of end members includes a trunnion. The valve assembly further includes a valve shaft received in the trunnion of each of the pair of end members. The valve assembly includes a valve plate connected to the valve shaft. The valve plate is rotatable between a first position and a second position. The valve plate is adjacent to the valve seat when the valve assembly is in the first position.

Valve assembly

An injector for injecting a reagent includes an axially translatable valve member positioned within a housing. A flux sleeve is surrounded by a coil of an electromagnet. A pole piece defines a return passageway for reagent to flow. A filter surrounds the pole piece and includes a cage and a mesh fixed to the cage. The cage includes a deformable first seal biasedly engaging an outer surface of the pole piece. The cage includes a second seal biasedly engaging the housing. The first and second seals define a closed volume such that all of the reagent flowing through the injector passes through the mesh.

An injector for injecting a reagent includes a first injector body and a second injector body. The first injector body includes an outlet opening. The second injector body includes a reagent tube. The second injector body is movable relative to the first injector body. The injector further includes a valve assembly at least partly enclosed by the first injector body. The valve assembly is configured to selectively dispense the reagent through the outlet opening of the first injector body. The injector further includes a spring member positioned between the first injector body and the second injector body. The spring member is pre-loaded to bias the second injector body towards the first injector body. The spring member is further configured to limit a maximum movement of the second injector body relative to the first injector body in response to expansion of the reagent during freezing.
