Abstract
A valve which minimizes fluid turbulence. The valve body has inlet and outlet ports at the end of threaded counterbores. Threaded collars mounted on the ends of the conduits are locked in place in the counterbores. A flange such as a snap ring on the conduits is engaged by a transverse wall on the collars to prevent movement of the conduits away from the valve body. A sliding valve element containing a flow opening permits fluid to flow through the valve when in open position. The interior of the valve body, the opening in the sliding valve member, the inlet and outlet ports and the inside diameter of the conduits are the same dimension with no gaps therebetween, creating a smooth bore.
