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.
