Abstract of the Disclosure A top entry flow control valve having a body with an inlet port, an outlet port and an access opening. The body has a cavity connected with the access opening and communicating with the inlet port and outlet port to allow fluid flow through the valve body. A pair of discs with orifices are positioned within the cavity to control flow into the outlet port by rotating one of the discs to change the degree of alignment between the disc orifices. A sleeve, a wear sleeve and a rotatable cylinder are located within the cavity to control flow from the inlet port. The sleeve and the cylinder both have side walls with a set orifices. One disc is secured within the open end of the rotatable cylinder and the other disc is secured to the wear sleeve. By rotating the cylinder, the alignments of the sleeve orifices with the cylinder orifices and of the orifices of the two discs are changed to control flow through the valve. A cover is removably attached over the access opening and secures the sleeve, the cylinder, the wear sleeve and the discs in the cavity. The cylinder and wear sleeve have sets of flanges or threads which cooperate to allow the cylinder and wear sleeve to be installed into and removed from the valve body separately or together. The valve may also be constructed without the sleeve.
