API Valves are used for bottom loading and unloading of petroleum tankers. Valve nose shape and opening comply with American Petroleum Institute standard (API RP-1004) enabling Dixon's API valves to interchange with competitor items made to the same specification. Two styles are available: a load model without handle and, a load/unload model with a handle to allow manual opening.
Fixed handle without sight glass, ALH nose ring and Teflon® seals
