Abstract
A safety valve limits but does not curtail flow of fluid from a source through the body of the safety valve upon release of a handle. A pivotable vane disposed within the body is urged to pivot from a first state not restricting fluid flow to a second state restricting fluid flow in response to the force of the fluid flow. A shaft supporting the vane is connected to the handle. Retaining the handle in a position commensurate with the first state of the vane will permit fluid flow through the safety valve, which fluid flow will become limited upon release of the handle due to a change in state of the vane.
