ABSTRACT:
A valve has a seat that is replaceable without disassembly of the bonnet from the body or removal of the stem and closure member. The seat is maintained in a fixed position within the body of the valve by a single retainer member that is readily separable from the body. The seat and closure member are formed of hard, wear- and corrosion resistant materials and the valve has internally disposed seal members to prevent leakage around the seat and retainer. The valve is particularly useful for controllably conveying high pressure and high temperature fluids such as steam.
