摘要： A valve seat includes an annular sealing surface comprising a rubber-lubricant mixture; and a seat body. A valve includes a valve body; a valve element disposed within the valve body; and a valve seat comprising a rubber-lubricant mixture, the valve element configured to seal against the valve seat. A method for forming a valve seat includes mixing a raw rubber with a lubricant to form a rubber-lubricant mixture; placing the rubber-lubricant mixture into a mold configured to form a valve seat; and curing the rubber-lubricant mixture.

摘要： Exemplary embodiments are directed to valves, generally including a body assembly and handle assembly. The body assembly generally includes a body and a stem passing through the body. The handle assembly generally includes a handle body and an insert. The insert provides an interface between the stem and the handle body. The insert includes protrusions extending therefrom configured to distribute stress resulting from a moment load applied to the handle assembly through the handle body to reduce failure of the handle body. Methods of positioning a valve are also provided.

摘要： A butterfly valve for handling materials where the temperature of the materials flowing through the butterfly valve can exceed the breakdown temperature of the sealing member with the butterfly valve inhibiting contact of hot transportable materials with the sealing member to isolate the hot transportable materials from the sealing member. Cooling conduits maintain at least portions of the valve that contacts the sealing member at a temperature below the breakdown temperature of the sealing member to prevent seal failure.

摘要： A butterfly valve with an undulating sealing surface, which has an inflatable annular seal mounted in a housing. A disk is pivotally mounted in the housing and has an edge with an undulating sealing surface and a peripheral sealing edge. The undulating sealing surface of the disk and a sealing face of the annular seal have non-mating profiles when the valve is in an unsealed condition. Pressure in a chamber proximate the annular seal causes the face of the annular seal to expand and deform and the face forms a high-pressure seal between the sealing ridge and the annular seal. Also includes a method for stopping delivery of a conduit transportable material through a butterfly valve.
