A valve has removable internal components including a disc, an orifice plate, and guides for engaging and guiding the disc. The internal components are removably secured to a valve seat plate by tee bolts. The seat plate is drilled, bored, or machined to include a plurality of cavities. Each cavity has a cantilevered projection extending over avoid in the cavity, and a slot is formed in each projection to form a tee slot for receiving the tee bolt. Each tee bolt has a head which is slipped into the void in the cavity so that the head engages the cantilevered projection while a shank of the tee bolt extends outward through the slot. The orifice plate has bolt holes for receiving the tee bolts, and an opening in the orifice plate is aligned with a passageway through the valve. A nut is tightened onto the shank of each tee bolt. After extended service, the tee bolts are still easily removable and replaceable, and the tee bolts can be aligned with bolt holes in a replacement orifice plate.
