Abstract

A valve plug assembly adapted for sealing engagement with a seat ring. The valve plug assembly includes a valve plug having a sealing disk adapted to engage a seating surface the seat ring. The seating surface of the seat ring has a primary portion with a primary angle of any one of about 20 degrees to about 45 degrees and a secondary portion extending from the primary portion with a secondary angle of about 10 degrees. A retainer is coupled to the valve plug and includes a body having a first portion, a second portion, and a side extending from the first portion to the second portion at one of an angle of about 30 degrees to about 45 degrees. So configured, the stress acting on the sealing surface is reduced, increasing the service life of the sealing disk.

Abstract

An internal valve includes a valve body, a valve stem, a poppet valve, and a bleed valve. The bleed valve includes a body with a bore. A spring seat fits within the bore and is coupled to the valve stem, and includes a guide sized to receive the valve stem and a flow aperture. The flow aperture defines a connecting bleed path that fluidly connects a bleed flow path and a bleed outlet. The valve stem shifts from a first position where the poppet valve and the bleed valve are closed, to a second position where the bleed valve is open and the poppet valve is closed, and a third position where the poppet valve is open and the bleed valve is closed. A spring disposed in the bore bears against the spring seat and is arranged to close the poppet valve and open the bleed valve.
