ABSTRACT:
A control valve that minimizes sticking of the plug assembly by particles such as welding byproducts in the associated heating system. The valve port having a continuous decrease of diameter from the port opening toward the valve seat and an additional stepped decrease in diameter adjacent to the valve seat, which enables particles wedged in the clearance between the plug and port to be released and guided away from the port.
