A flow control valve includes a valve body having a first section and a second section attached to the first section. A flow control member is positioned within the valve body and a shaft extends through the valve body and is connected to the flow control member to move the flow control member between an open position and a closed position. A sealing gasket is positioned within the valve body and engages the valve body to prevent the flow of fluid between the first section and the second section. The sealing gasket has an annular metallic body having an inner surface and an opposing outer surface, the outer surface defining a primary sealing surface, a groove formed in the outer surface, and an insert positioned within the groove, the insert defining a secondary sealing surface.

Purge apparatus for use with fluid valves are disclosed. An apparatus includes a stem for a fluid valve. The stem has a first channel extending therethrough to receive a fluid. The apparatus also includes an aperture in fluid communication with the first channel and disposed on an outer surface of the stem or a fluid flow control member coupled to the stem. The aperture is to exhaust the fluid from the first channel toward one or more components of the fluid valve to remove residue.

Purge apparatus for use with fluid valves

A rotary valve is provided for use in highly corrosive and abrasive applications. The valve includes a valve body and an adapter coupled to one end of the valve body, thereby defining an inlet, an outlet, and a valve interior in fluid communication with the inlet and the outlet. The valve also includes a floating ball element pivotably mounted in the valve interior via a valve stem to control fluid flow through the valve, a first valve seat movably disposed in the valve interior, and a second valve seat removably disposed in the valve interior. The first valve seat is biased toward the ball element to sealingly engage a first portion of the ball element. The second valve seat is configured to sealingly engage a second portion of the ball element and is clamped between a surface of the valve body and a surface of the adapter.

A valve apparatus may include a control valve including valve body having an inlet, an outlet, and a flow path. A rotational valve stem may extend along a longitudinal axis, the valve stem having a top portion and a bottom portion, the valve stem operatively coupled to a control element movably disposed in the flow path. A yoke may be attached to the valve body and arranged to operatively couple the valve body to an actuator, the yoke including a first bracket having an aperture and a second bracket having an aperture. A bushing may be arranged to align an actuator shaft of the actuator to the longitudinal axis of the valve stem, the bushing having a first portion and a second portion, the first portion engaging within the aperture of the first bracket and the second portion engaging the aperture of the second bracket.
