Abstract
A line-removable ball valve including a rigid framework or box with opposing, parallel, thick steel end plates. A valve cartridge with all components carried therein is received between the parallel plates and a seal carrier ring, carried on and sealed with an end closure of the cartridge, is biased outward to seal against the inner surface of each of the parallel plates to form a fluid-tight unitary structure. The biasing force acting against the seal carrier is relieved for removal of the valve cartridge from between the steel plates.
